出国留学GPA究竟有多重要？作为体现学生在校成绩和学习能力的主要指标，GPA无论是在本科还是研究生申请中，都是招生官重点关注的对象。出国留学GPA如果太低，往往会影响招生官对申请者的第一印象，但有没有补救方法？今天求真老师将为大家分享补救低GPA的一些方法。

什么是GPA？

GPA全称Grade Point Average，即成绩平均绩点，是大多数美国大学及高等教育院校所采用的一种评估学生成绩的制度。美国的GPA满分是4分，即A=4，B=3，C=2， D=1。GPA的精确度往往达到小数点后1到2位，如：3.0，3.25。GPA的计算一般是将每门课程的学分乘以学时，加起来以后除以总的学时，得出平均分。

该怎么拯救低水平的GPA？

下定了赴美求学的决心，奈何GPA没有竞争优势，那么还会有别的补救办法吗？答案是肯定的。

1.提高标准化成绩分数：出国留学GPA能直观体现学生的专业能力，但GMAT、GRE、托福、雅思等标准化成绩同样可以体现学生的学习能力。在GPA不足的情况下，出众的标准化考试成绩能弥补在校成绩方面的劣势。

2.突显课外活动/科研经历/实习经历中的闪光点：成绩并非美国大学招生的唯一标准。招生官青睐的往往是在课堂上、社交上、实践中都表现优秀的综合型人才。因此，求真老师建议同学们尽早确定自己感兴趣的专业方向，并在此基础上有针对性地参加深层次的课外活动。对于申请研究生的同学而言，与申请专业相关的实习经历以及个中收获尤显重要。

3.一份出众的文书材料：文书是招生官最能了解到申请者的材料。一份好的文书材料能让你最大程度展现你对所选领域的热情以及个人素质，帮助你在低GPA的情况下仍能以出色的综合能力打动各大招生官。求真教育拥有一支美籍文书专家顾问团队，能在与你头脑风暴中充分挖掘你以往经历中的闪光点，助你获得招生官青睐，为你插上通往梦校的翅膀。

4.对低GPA作出合理解释：求真老师建议同学们在申请美国大学时，充分利用网申系统所提供的“Additional Information（附加信息）”一栏，对低GPA作出解释。无论是出于主观原因，还是由于专注自己感兴趣的领域而耽误专业学习，又或是受身体原因影响，同学们都应该客观地解释清楚GPA低的原因。美国大学尊重客观事实，如果申请者低GPA的情况情有可原，并且在其他能力上体现出巨大潜力，这样被录取的机会依然很大。

求真寄语

出国留学GPA非常重要，但GPA没有竞争优势的同学们也不要气馁。寻求专业的留学机构帮助，合理规划留学方案，在课外活动和文书上展现自己的闪光点，你也一样可以得到招生官的赏识，斩获梦校录取。求真教育坐落于美国洛杉矶，自2007年成立以来，已经助力上千名学子收获美国名校录取。出国留学GPA太低不要怕，求真教育拥有一支专业、富有经验的专家顾问团队，会为你量身定制留学方案，助你飞跃名校！

纽约大学转学近年来已经深受大家的欢迎。纽约大学作为全美前30顶尖名校，由于其位于美国东部金融、经济大都市纽约，每年毕业生都拥有非常好的就业方向和职业发展方向。另外，由于排名靠前、筛选严格，每年直接申请竞争激烈。很多同学会通过先申请社区大学或者排名稍低的学校，再通过纽约大学转学这一捷径成功圆梦。求真老师今天就和大家聊聊纽大转学过程中那些需要注意的细节，让同学们有更加清晰的了解。

名校底蕴深厚，顶尖人才辈出

纽约大学成立于1831年，主要的校区位于曼哈顿格林威治村，因其顶尖的研究水平以及优异的就业质量和校友网络。另外，由于纽约是美国经济中心，很多世界五百强、跨国公司以及全球知名集团都将办公室设立于此。另外，纽约也是世界文化的中心，著名的百老汇、大大小小的艺术展览室和博物馆，让人们能够亲身接触高雅艺术，近距离和顶尖艺术家对话。纽约大学还培养出了许多知名校友，例如著名导演李安、美国流行天后Lady Gaga、著名女演员安妮海瑟薇等。

转学纽大，你需要提前规划

纽约大学转学需要同学们提前做好准备。不论是在社区大学或者其他四年制大学中学习前两年的通识教育课程，同学们需要在数学、英语、社会科学、人文科学、自然科学等科目中选择足够的学分。我们建议学生可以提前和学校的指导老师和高年级的师兄师姐沟通，合理安排好自己的课程，避免踩雷。好的选课在转学纽大过程中十分重要，因为如果没有拿到各个专业要求的课程学分，同学们就只能与纽大失之交臂。求真教育老师们建议同学们提前做好功课，确定好各个专业所需要或者推荐的课程有哪些，并且对课程大纲、历年开设情况、学生对教授评价等多维度来安排自己的课程表。

https://cdn.indeededu.com/uploads/2020/01/NY-80x80.png 80w, https://cdn.indeededu.com/uploads/2020/01/NY-36x36.png 36w, https://cdn.indeededu.com/uploads/2020/01/NY-180x180.png 180w, https://cdn.indeededu.com/uploads/2020/01/NY-120x120.png 120w, https://cdn.indeededu.com/uploads/2020/01/NY-450x452.png 450w, https://cdn.indeededu.com/uploads/2020/01/NY.png 555w" data-sizes="(max-width: 300px) 100vw, 300px" sizes="(max-width: 300px) 100vw, 300px" srcset="https://cdn.indeededu.com/uploads/2020/01/NY-300x300.png 300w, https://cdn.indeededu.com/uploads/2020/01/NY-80x80.png 80w, https://cdn.indeededu.com/uploads/2020/01/NY-36x36.png 36w, https://cdn.indeededu.com/uploads/2020/01/NY-180x180.png 180w, https://cdn.indeededu.com/uploads/2020/01/NY-120x120.png 120w, https://cdn.indeededu.com/uploads/2020/01/NY-450x452.png 450w, https://cdn.indeededu.com/uploads/2020/01/NY.png 555w" /> 图源：freepik

选课是大一大二通识教育十分关键的一个环节。求真老师不建议新生选太多课程，毕竟我们需要把有限的时间放在紧张繁忙的学业当中。而且除了课程学习之外，同学们还需要多注重自己的背景提升。社团活动、志愿者经历、体育赛事、科研项目等等都会是不错的选择。纽约大学转学时还注重申请者的领导力和创造力等个人品质。在递交网申时，同学们需要先静下心来，思考下学校录取我的理由有哪些以及我为什么选择纽约大学作为申请学校。如果你对这两个问题有清晰、通顺的答案，并且能从自己的活动经历中提炼出自己对于领导力、创造力等品质的理解，你离纽约大学又将会更进一步。

纽大转学专业如何选择

众所周知，纽约大学许多专业如经济、工程、计算机科学、统计学等每年竞争都十分激烈，那如何选择专业成为让许多留学生头疼的一个难题。在做决定之前，我们应该综合考虑我们前两年对各门课程的学习感受、成绩、自身兴趣以及就业趋势。专业选择的过程中一定要有自己独立的思考和判断，切忌人云亦云，导致之后无法顺利完成自己美国大学学业。美国大学实行宽进严出的制度，且本科GPA不能低于2.0。因此，在纽约大学转学专业这个问题上，我们建议同学们找到你身边专业的求真团队老师，一起探讨最适合自身的专业方向，并且结合目前就业趋势规划好之后两年的学习计划，做到有的放矢。

求真寄语

纽约大学转学对于同学们而言是一次重要的转身机会。希望同学们能提前做好规划，并且和求真转学团队老师积极沟通，积极拔高自己的硬件和软件实力，争取在完成两年的学业后，凭借优异的成绩成功转学纽约大学。

美国紧急转学

美国紧急转学对刚来到美国留学的同学来说可能比较陌生，是发生了什么事情，才会需要进行美国紧急转学呢？美国的教育体系的宽进严出可不是开玩笑的。毕业有多难，在美留学生深有体会。考试作弊、作业未能按时交、成绩不达标、出勤率不够等等远远都可能带来警告、停学甚至开除的处分。

P同学案例

P同学在美国一所排名靠前的学校就读计算机科学专业。计算机科学专业的课业难度十分大，P同学进入学校后学习就一直处于中下的水平。等到了大三开始进修大量的专业课后，P同学更是倍感吃力，很难跟上课堂进度，成绩严重下滑。最终由于GPA连续两学期没有达到最低2.0标准，收到了学校的开除处分。

求真助力

P同学收到开除处分后，并没有很吃惊。因为深知美国的宽进严出政策，这个结果也算预料之中。P同学立刻在网上寻找解决办法，在求真教育官网看到与自己相似的案例后马上联系了求真客服老师。客服老师第一时间安排了张老师与P同学沟通。

在沟通过程中，张老师了解到P同学还是一个爱学习的孩子，基础也是比较扎实的。GPA一直不达标是因为没有掌握科学的学习方法。但是目前保住P同学在美国的合法身份才是首要任务。

由于P同学已经连续两个学期GPA不达标，所以申诉成功的机率不大。但是张老师还是建议P同学进行申诉，因为申诉的同时可以为自己争取更多的时间去寻找合适的学校。张老师这边紧锣密鼓地开始为P同学寻找合适的学校，最终顺利帮住P同学转到了新的大学，保住了I20。

到了新学校，并不意味着事情就结束了。P同学继续选择求真教育为其提供学术辅导。求真教育专业的辅导老师根据P同学的情况帮住他梳理了专业课的内容，对知识点进行了查缺补漏。经过一学期的努力后，P同学在新学校取得了不错的GPA成绩。最终在求真教育的帮住下，P同学又顺利申请转回了原校。

求真寄语

在美留学中如果发生了像P同学这样的事情，一定要保持冷静，第一时间联系专业的机构帮住解决。你的美国留学之路，求真来守护。更多资讯，尽在求真。文章来源：https://indeededu.com

美国留学转学对很多没有进入理想的美国大学学习的留学党来说，是冲击理想学校、实现自身梦想的第二次机会。要知道，申请美国留学转学也要提前做好规划。求真教育小编跟各位留学党聊聊，应该怎么准备美国留学转学！

大学转学基本流程

2020年2月-4月：递交美国留学转学申请，务必在学校的截止日前完成网申，需要邮寄的材料也要提前寄出，确保在Deadline前寄到，申请费也别忘了付哦！全部寄出材料后还需常常查收邮件，看看是否学校有新的材料要补充填写和提交，有什么不明白的要及时和学校邮件或电话沟通。

2020年4月-6月：等待Offer。申请多个学校的同学可以等所有offer都收到后，根据学校的学费、奖学金等情况进行选择，并且在学校给出的deadline之前回复是否接受offer。

2020年5月-7月：收到Offer后就可以着手办理学校手续了。学生需要和原校的国际学生办公室说明，把自己的SEVIS号码以及档案转到新学校。

2020年7月-8月：根据个人情况，回国办理新的学生签证。准备开学事宜。

2020年9月：开学！

提前规划

决定转学前，要先了解清楚目标学校的标准跟要求，不要盲目，特别要注意学校对转入学分和课程的要求。

首先要先选好学校，建议选择适合自己的学校。之后确定好自己的时间规划，不同的学校申请开放、截止的时间都不同。所以要先选择好学校和专业，可以有针对性地安排时间，比如给学校发信询问具体什么时间开始招生，申请截止时间是什么时候等。

另外，学分总数和课程要求要有所了解。学分总数的要求、多少分可以转学、多少学分免考SAT。不同的专业可以转的学分不相同，尤其是跨专业转学的学生，学分即使满了30分也有可能要考SAT，而且不同课程的比例越多，审核的周期也越长。这些要求在各个学校的申请要求中都会列出来。

因此定校之后，一定要确认学校官网上的课程学分和录取要求。这样做可以让你腾出更多时间准备托福考试，让不满足的条件的学生可以提早准备SAT。

美国留学转学申请资料

转学材料需要在截止日期的前4个月开始准备。如果是申请加州大学系统，那学生在暑假期间就应该开始准备材料了。这些材料主要包括：大学GPA成绩单、推荐信、个人陈述、个人简历和标准化考试成绩等，再根据不同学校不同专业的具体要求提供相关材料。

GPA非常重要！美国大学非常在意申请者在目前学校的GPA和排名。好一些的大学将3.0以上的GPA当作门槛，3.5以上的GPA对于转学到前30名的学校更有保障，一些竞争热度高的专业，例如计算机科学、电子工程、土木工程等，需要更高的GPA。建议现在还不知道自己GPA多少分的同学进入WES官网注册一个账号，算一下成绩单上的平均分转化成美国GPA是多少，做到心中有数。

标化考试中托福和SAT这两项是大一转学生要准备的，一般TOP50的大学对于托福的要求都不一样。很多学生单纯地复习但是没有进度和变化，原因出在策略和方法上，量够了但是分提不上去，这时候不能坐以待毙，要尽快找专业机构像求真教育咨询问题所在。尽快掌握正确高效的复习方法，在12月之前考出有效的标化成绩。

申请文书方面也需要下比较大的功夫。简历一般涵盖学术表现、工作经历、社会活动、社区服务、技能等五个部分，高质量地填充这几项内容能提高录取几率。同样，优秀的短文和个人陈述在美国留学转学的录取中起着举足轻重的作用，学校需要从你的文章中看到你的激情和你的梦想，对你进一步的了解，所以短文和个人陈述的技巧是极高的。在写作时，一定要仔细省题，换个角度想想为何招生官想知道这些信息，进而巧妙地回答。如果感觉到困难，不妨咨询留学专家求真教育，专业地道的文书团队能为你提供很大的帮助。

求真寄语

转学需要注意的事情非常多，很多人会在查找资料阶段就有放弃的念头，但又不甘于现状。只有行动起来，梦想才有成真的可能。如果你认为你自己无法同时专注于在校GPA、标准化成绩考试、充实简历等等多方面事情，留学专家求真教育可以为你提供最专业、最贴心的服务。求真教育拥有多年美国留学转学、学术规划辅导经验，助你轻松踏入美国名校。

美本申请

学生：S同学

高中：国内普通高中

GPA：90+/100

TOEFL：80+

ACT：25

录取学校：加州大学欧文分校等

S同学是国内某普通高中的学生，在10月中旬找到了求真教育想要进行美本申请。当时他的托福只有60多分，并且没有什么大型学术奖项和课外活动。申请老师立刻在脑子里构思了对S同学的申请规划，什么时候应该考出标化成绩，什么时候应该开始美本申请等等。通过和他的沟通，申请老师发现虽然他暂时还没有什么特别突出的长处，但是S同学是个很认真努力的人，所以心里暗暗地对他抱有一定的期望。

求真助力

经过和S同学的深入接触，求真教育的老师发现他在国内高中表现十分不错，且课外活动中有持续性较较久的项目。于是文书老师从这一点入手，将文字材料做的非常细致，把学生的信息高度提炼并梳理成一个完整的故事，文书的立意也和普通学生不尽相同，将“生与死”这个高中生不太涉及主题融入了主文书，凸显了学生的与众不同。

与此同时，S同学在一心准备标化成绩，终于在11月份，托福考出了80+分，ACT考出了25的成绩，相较于之前的硬性条件有了很大的提升。但由于学生和老师都寄希望于加州系统的申请，这样的综合条件并没有给我们树立太大的信心，于是老师们更加专注于课外活动的构思和文书的润色上。在除加州大学外的学校选择上，申请老师也经过层层筛选，选择出了最符合S同学条件的学校名单。

最终，S同学在来年三月份收到来自宾州州立大学帕克主校区的录取。学生非常的激动，微信上连连说“爆炸了”，并且专门打电话给申请老师问是不是真的录取了，当得到肯定的答案后，学生和家长都频频感谢老师的辛勤付出。后来我们又陆续收到加州大学欧文分校，俄亥俄州立大学等其他大学的录取，这样的结果所有人都非常满意。

求真寄语

很多学生找到求真教育想做美本申请的时候，都还没有合适的标化成绩和清晰的申请思路。我们凭借多年的申请经验和丰富的学生案例，对每一位学生都能快速和精准地定位，找到最适合他们的申请之路，并且在各方面给予最专业的帮助。在这里，求真教育也想要祝S同学的留学之旅一切顺利！

美国留学申请

美国留学申请 怎么做，你有详细的时间规划吗？虽说留学申请季明年9月份才正式开始，但准备工作必须得提前开展。收下这份详细合理的美国留学申请时间规划表，各位准留学党就能不慌不忙把名校offer揽入怀中。

美国留学申请 规划早，入读名校阻碍少

1月-3月

1. 选择学校：选校需谨慎，我们要考虑很多因素，比如地点、学费、声誉、规模、多样性等。最重要的，当然还有学校和专业排名，这方面同学们可以参考U.S. News和QS发布的美国大学排行，如果你拿不定主意，可以来咨询留学专家求真教育。

2. 标准化考试：美国留学申请的必备条件之一就是标化成绩，一般包括雅思（现在大多数美国大学都认可雅思成绩）/托福、SAT、SATII；申请研究生则需要提交托福、GRE（对申请理工科学生而言）或者GMAT成绩（对申请商科学生而言），具体要根据申请的学校和专业来定。取得理想的标化成绩是取得名校offer的重要一步。求真小编在此温馨提示：一定要提早规划，提前报名。

4月-6月

3. 自我提高：准备美国留学申请时，GPA成绩也是一个比较重要的环节，所以在校期间同学们要尽可能提高自己的GPA成绩。如果自己的标化考试成绩不理想，也可以在这段时间刷分。

另外，想要后期文书内容丰富，增强个人软性实力也十分关键。个人软实力的增强则依靠活动的规划。活动类型包括社团类、科研类、竞赛类、实习等等，能持续性、层次性地锻炼个人的综合能力。求真小编提醒：背景活动要注重质量和深度，而不是一味追求数量。

7月-8月

4.证明材料准备：对于申请美国本科生的同学来说，一般需要提供高中的成绩单。而申请研究生的同学则需要提交本科四年的成绩单。需要注意的是，部分院校的研究生项目还会要求申请者提供相应实习证明。材料准备是一个繁杂的过程，这个过程中肯定会遇到这样那样的问题。求真团队可以协助同学们进行资料准备，保证资料的完整和及时。

5.文书创作：需要准备的文书主要包括个人简历、个人陈述、小论文和推荐信。个人简历要有很强的针对性，需要能体现申请人的需要和申请目的。根据不同的美国大学要求，申请者需要提供1-5篇不等的个人陈述，推荐信则一般需要2-3封。

小编建议：最好5月份就开始文书构思，7月份前就沟通确认好至少2个学校推荐人，为7、8月专心写个人陈述和小论文留出足够时间。文书是同学们向招生官展示个人软实力的重要途径。优秀的申请文书能给招生官留下深刻的印象，增加录取成功率。求真专业团队可以提供全程一对一指导，拒绝流水线文书创作，为同学们打造最完美的文书。

9月-第二年2月

6.正式开始申请：9月正式进入美国留学申请季。要注意的是，不同学校的申请截止日期都有所不同，即使是同一所学校不同专业的也会不一样。同学们应密切关注目标院校的截止日期，切勿错过了申请时机。

另外，有一些网申小贴士要告诉大家：有固定统一截止日期的美国院校一般都是在截止日期之后才进行材料审核，即是说，无论提交早晚，都不会影响录取几率的。但一些院校的截止日期是分轮次的，比如哈佛的MBA截止日期就分3轮：第一轮9月9号，第二轮1月6号，第三轮4月4号。通常，第一轮的录取率最高。因此，建议同学们第一轮就提交申请。

第二年3月-5月

7.后续工作：提交网申后，同学们可能会收到部分学校的面试通知，因此一定要时常跟进申请状态，避免错失面试机会。小编在这里提醒申请者要尽早进行模拟面试练习，提高自己的通过率。另外，可以及时向学校更新自己的标化成绩。如果一直没有收到院校的通知消息，同学们要及时发邮件询问院校自己的录取结果。

8.获得录取通知：如果同时收到多所院校的录取通知，同学们应该多方衡量后选择最适合自己的院校。

第二年6月-7月

9.签证申请：赴美留学需要先获得F-1签证。签证流程包括准备签证材料、预约签证。美国教育机构会给每位收到offer的F-1签证申请人提供申请签证所需的批准文件I-20。一定要核对文件上的信息是否正确，如果有误就要及时联系学校进行修改。

10.入学待办事项：录取院校的学生后台一般会给出一份新生入学的待办事项清单，同学们及时查阅学生邮箱，获取清单。要认真阅读清单，在截止日期前完成上面的内容。一般来说，入学待办事项会包括寄送原校成绩单、完成疫苗要求、提交经济保单证明等等。

一切就绪，同学们只要收拾好自己的行囊和心情就可以漂洋过海，开始自己的留学生活！

ASTM A53 can be formed and welded. Specify the correct pipe size using the nominal pipe size (NPS). This is the nominal pipe diameter for specified wall thickness (i.e., 4 inch Schedule 40 pipe). ASTM A53 grade b erw pipe is determined according to the nominal pipe size (NPS) system. It is usually available with national pipe thread ends or with plain cut ends. It can be used for the transportation of steam, water, and air. It is also weldable and can be used in structural applications, although A53b steel pipe tub, which is available in the same NPS sizes, is sometimes can be the first choice.

Executive standard: ASTM A53 welded steel pipe for low-pressure fluid transportation ASTM A53 straight seam electric welded steel pipe" Q/HBTC 001-2016 "welded steel pipe"   

Scope of application: conveying low-pressure fluids such as water, air, heating steam and gas; structural use such as machinery and construction.

Most homebuyers consider dozens of houses before finding the perfect one, but that’s not the case when it comes to picking a real estate agent. Seven out of every ten homebuyers don’t interview their agent before deciding to work with them.¹ That’s pretty scary considering not all agents are created are equal — as the industry saying goes, 20 percent of the agents do 80 percent of the business. If your real estate agent could make the difference between landing your dream home in a few weeks or losing bids, why wouldn’t you shop around?

Finding an agent who is both good at their job and easy to work with isn’t always simple. That’s why we suggest interviewing at least a couple of real estate agents before picking “the one”. Here are some guidelines for how to decide which agent is a good fit for you.

1. Experience

With markets getting more and more competitive, you want a real estate agent with a proven track record of putting people in their dream homes. Read online reviews, talk to past clients, and most importantly, ask if the agent has recently closed on properties similar to what you’re looking for. Pay special attention to their history with homes in the location and price range you are considering.

2. Expertise

Working with someone who is familiar with your desired area helps to ensure that you’ll only spend time and energy on houses that fit your criteria. First, decide on the factors you want to prioritize in your neighborhood search (schools, walkability, nightlife, etc.), and then, go through them with your prospective agent to get a feel for their local knowledge.

3. Empathy

Ultimately, you want to make sure your agent is someone you are comfortable working with. The house hunt can sometimes take months, especially in competitive markets. Working with an agent who shares your communication style can help make the journey enjoyable rather than stressful. Spend some time thinking about the type of person who you’ll be able to work well with. Do you want someone who is patient and will guide you through the process? Or do you want someone who works fast and is straight to the point? (Your answer will probably be different depending on whether or not you’re a first-time homebuyer or familiar with the area.)

Need help finding the right real estate agent? While there is no obligation to use our suggested agents, we can help you save time and energy by introducing you to one who has been vetted by our team. Every agent we suggest has a strong track record of success. Schedule a free consultation to learn more.

Tamper evident bags have become a common security measure in many food and beverage products to prevent contamination and spillage and maintain the integrity of the finished product. Tamper-resistant seals, rings and pouches ensure the quality and freshness of the product, and provide manufacturers with a degree of security. The complete tampering technology in the tamper evident bag conveys the safety and reliability of the finished product, but production errors may occur during the final sealing stage of the primary packaging, affecting the safety seal. The normal wear and tear of production machines makes it almost impossible to make 100% defect-free products, so quality control and inspection processes are essential to prevent these products from leaving the production line and entering the market.

After checking the product's fill level and placement of the lid, the vision system checks the seal to verify the integrity of the seal, and specifically verifies that tamper resistant bags and security seals are used. For bottles with safety rings, the vision system verifies that the rings have not been lifted and have been properly twisted.

A vision inspection system with pattern matching technology quickly locates and verifies the integrity of tamper-resistant seals for accurate and repeatable inspections. Detect edges of security seals and measure their height, width, relative position, and gap size, and compare them with set limits. Tamper-resistant seal dimensions that do not meet the programmed limits will be rejected.

As one of the tamper evident tape suppliers, our company has shown its worth in this very competitive sector due to theefforts and rigorous inputs from the professionals who have contributed immensely to its growth. These people have a very vast knowledge of the market trends and scenario allowing them gets reliable link-ups with vendors for us. Also, we have some of the best-qualified quality and packaging experts, who have taken responsibility to ensure we make zero-defect products as well as safe and on-timedelivery of the packaging materials.

The liner hanger assembly is a special cementing tool for tieback operation.

Tieback equipment allows existing liners with a receptacle to be extended to the surface or farther up hole, and provides a high-pressure seal at the top of a cemented or uncemented liner. TIW offers variety of tieback seal nipples and tieback packers to accommodate liner top extension and remedial operations.

Tieback Procedures of Hydraulic Liner Hanger Tie-Back Assembly

1. Preparation before casing

Measure and drift the casings carefully and clean all the threads.

Calculate the kelly-up of the casing (the particular part of the last casing which is above the rotary table) and arrange the casing string.

Prepare several casings, which are approximately 0.5m shorter than the others and convenient for kelly-up calibration. (The actual kelly-up is not equal to the calculated value due to measurement error and the remaining threads of the casings.)

1. Polishing the polished bore receptacle

Connect the milling shoe and trip in. Polish the inner surface of the polished bore receptacle, make sure there is no debris.

Note the depth of the milling shoe when it reaches the top of the seal assembly (judge from the changes on pressure and WOB). Then lift the drill string for 1m.

Use a drilling rate of 40～50rpm and a normal flow rate. Slowly lower the drill string. Polish the inner surface of the polished bore receptacle twice or three times. Each time polish 3～4min. During the last polishing, apply an additional load of 2～3t when the torque suddenly increases (the milling shoe reaches the top of the seal assembly) during the last polishing. Polish for another 2~3min and note the depth of the milling shoe, which is an important clue for the casing setting depth.

Circulate with high flow rate for 5min.

Trip out and check the milling shoe. If there is a circle of polished trace and the diameter is equal to the I.D. of the left thread on the seal assembly, then the milling shoe have reached the bottom of the polished bore receptacle.

Features of Hydraulic Liner Hanger Tie-Back Assembly

With the guide shoe and circulate bore, it can stab into polished bore receptacle before cementing, more convenient than conventional cementing which pumps down cement before stabbing.

With its streamline shape, the guide shoe can stab into polished bore receptacle easily.

The Tieback Seal Assembly with three stacks of molyglass seal is designed for high-pressure and high-temperature liner tieback completions. Available in seal length is 1.2m.

ASTM A500 Steel Pipe

ASTM A500 is the standard specification for circular, square, and rectangular tubes of cold-formed welded and seamless carbon steel structures. ASTM A500 is the most common specification for Hollow Structural Sections in North America. The correct way to specify the circular HSS section is to represent the outer diameter in decimal inches to three decimal places (i.e., 5.563 x 0.250) according to the nominal wall thickness.

Why A500 Steel Pipe?

Since ASTM A500 is a structural specification, circular high-speed steel produced according to this specification is suitable for structural applications and general construction purposes. ASTM A53 is a pipe specification for mechanical and pressure applications.

The specified yield strength of  A500 Grade b Pipe(the most commonly available grade) is 46 ksi.  The specified yield strength of A53 Grade B is 35 ksi.  Yield strength increased by more than 30%.  Therefore, the strength to weight ratio of A500 circular HSS is greater than that of A53 pipe. So, if you do the job with round HSS, you need less steel, by weight, to do the job—the lighter it is, the lower the cost.

The tolerances of A500 are tighter than those of A53, so the HSS of the A500 circle has higher quality and less variability.

Round HSS has a superior surface finish and is not as lacquered as normal A53 tubes.  Since this lacquer coating needs to be removed from the A53 pipe to accommodate welding and painting, so this can save money and time.

A53 pipe is available in standard pipe sizes only.  Round HSS is available in various sizes and wall thicknesses. Just look at the 14th edition of the AISC Steel Construction Manual and see how many pages there are of circular HSS with A53 tubes.

Last but not the least, the ASTM A53 Specification requires testing (i.e., pressure testing) for structural applications. This additional testing adds unnecessary additional costs.

Astm A500 Grade C Pipe Applications

All steel structures have their pros and cons including tructural supports, building columns, highway signs, oil field services and communication towers, to name a few. But ultimately ASTM A500 is a better choice when you need a round profile.

We encourage architects, fabricators, structural engineers and contractors to read up on ASTM A500 and visit The Steel Tube Institute's website because it offers a wide variety of technical publications, load tables and design aids.

In its fight against counterfeit and inferior medicines, the EU responded with the anti-counterfeiting directive 2011/62 / EU. As of February 9, 2019, with few exceptions, prescription drugs can only be marketed with a security label and serial number. For pharmaceutical companies, implementing the EU Directive is a difficult task. According to the estimates of pharmaceutical manufacturers, the cost of implementing each EU pharmaceutical production line is hundreds of thousands of Euros.

Tamper Evident Label on Tamper Evident Bag

In order to be able to continue using the existing tamper evident bag, the use of tamper-resistant labels is an interesting option from a cost-effective point of view. Dedicated tamper-resistant labels have reliable packaging integrity, quality and safety guarantees. In addition to monitoring measures, this tamper-resistant label also means protection for consumers when buying medicines. At present, the materials used for tamper evident labels on tamper evident bags are usually some special materials, such as the so-called "fragile labels". The materials used for fragile labels are almost completely broken in every attempt to open. Or the so-called "Void Unmask" tag leaves irreversible handwriting when trying to unpack it. And these special materials have their own different shortcomings and shortcomings in the high-speed pharmaceutical production line, which means that a large amount of additional financial expenditure is required.

Label glue is the decisive factor

From an economic and technical point of view, the most reasonable labels are conventional rectangular or circular labels. What plays a decisive role in these labels is their pressure-sensitive adhesive. The heat-sensitive adhesive must have good water resistance and good resistance to hot air and various thinners. Only by possessing these properties can we guarantee that the label will not be easily peeled off from the colorful folding box without damaging the label itself or leaving visible signs of disassembly on the pill box. There is a pressure-sensitive adhesive R & D department dedicated to meeting various challenges. The pressure-sensitive adhesive developed and produced by this department can be used on various tamper evident bag surfaces. ZHANJIANG FENGQI PLASTIC PRODUCT CO., LTD not only develops and produces sealed labels, but also provides labeling machines for integration into packaging production lines.

It seems that most modern people do not go to physical stores to buy goods. They choose online shopping. Because more information about product types can be found only by searching in the Internet and more options in terms of price can be chosen, it has promoted the prevalence of online shopping. Because of this, the courier has a lot of boxes to deal with every day. Sometimes some goods will inevitably be squeezed. If you want to solve this troublesome thing, the security bag must be used.

What is a security bag?

In fact, after the security bag has been improved by various production techniques, its equipment operation speed and production efficiency have been greatly improved. In addition, it can be found that the production of security bags has also added some automated procedures in colleges and universities, which has avoided some errors caused by human operations. At this time, it can bring more high-quality products to merchants, so we need to understand some of its uses.

Basic uses and advantages of security bags

1. Anti-counterfeiting function

The most important function item of the security bag is its anti-counterfeiting effect. For a long time, all kinds of sealed bags have been in a basically suitable process. It is basically impossible to achieve related control and real-time tracking. Assuming that the product is repackaged or theft occurs during transportation, the interests of merchants and consumers will be directly damaged in the end. At this time, if the security bag can be used, then there is no need to worry about such problems.

2. Multiple protection

The development of security bags to this stage has basically used PE waterproof materials. This material has many advantages after a series of special treatments and steps. For example, it can easily be waterproof and impervious. In the process of transportation, if it is because of various unexpected external factors that affect the goods, it will definitely harm the interests of consumers and the express delivery company. However, the multiple protection of the safety deposit bag can enable the items to be protected with high quality during transportation.

3. Good sealing

Because of the material of this bag, it is definitely not easy to be damaged during transportation. After all, the bags are made together with a variety of chemical materials, so basically no damage will occur during the transfer process. The outside of the bag will be fixed with tape after being affixed, so it will not drop during transportation. In addition, the airtightness of the bag will be many times better than those of the previous express without using the bag, which can better protect the items purchased by the customer.

In fact, in addition to the above functions and uses, the security bag also has features, of course, it also has other advantages. For example, the sealing performance of the multilayer structure is particularly good. In addition, it also has an oil film protective layer, so it can achieve the purpose of waterproofing. In addition, its anti-counterfeiting characteristics are also unique, so its security performance is good. Its technology is powerful, and it has a unique feature that cannot be copied, so many businesses are willing to adopt it.

As one of the tamper proof bags manufacturers, our company has shown its worth in this very competitive sector due to theefforts and rigorous inputs from the professionals who have contributed immensely to its growth. These people have a very vast knowledge of the market trends and scenario allowing them gets reliable link-ups with vendors for us. Also, we have some of the best-qualified quality and packaging experts, who have taken responsibility to ensure we make zero-defect products as well as safe and on-timedelivery of the packaging materials.

With the development of technology, teachers have gradually discovered that the possibility of paper sealed bags being copied is too great. Therefore, the anti-counterfeit sealed security bag has become a test paper sealed bag favored by the school. A security bag, as the name suggests, is a bag with protection features. From this we can probably guess that the security bag of the test paper has the function of protecting the contents of the package from being exchanged and maintaining its uniqueness!

Its secret protection of objects is mainly reflected in the use of anti-counterfeiting technology.

The main anti-counterfeiting has the following types:

1. Self-adhesive sealing——Remove the reserved words

It uses a self-adhesive anti-counterfeiting seal, which has strong adhesion. Glue can withstand high and low temperatures, and it is not easy to be opened illegally. Once the security anti-counterfeiting tape is opened and the reserved words are opened, the anti-counterfeiting characters, characters and patterns will appear.

2. Temperature-changeable ink——Multiple anti-counterfeiting

The temperature-changeable ink anti-counterfeiting part will turn red when it encounters external high temperature up to 65 ° C, and cannot be recovered. In addition, when the ink encounters water, the ink will be dissolved by the water.

3. Unique barcode——Easy query

Each bag can be printed with a unique serial number and barcode. The unique bar code is easy to tear, used to track products and stubs, and can track goods by ticket number.

In addition to the application of anti-counterfeiting technology, items can be protected from being exchanged before being opened. In addition, the bag has the functions of anti-breakage and strong adhesion to protect the internal items from being damaged.

Anti-breakage: High-mild material can prevent tearing and scratching, easy to fill, and seal quickly.

Strong tackiness: The self-adhesive anti-counterfeiting seal has strong tackiness, the glue can withstand high and low temperature, and it is not easy to be opened illegally.

Waterproof / liquid-resistant: It uses high-grade PE / PO material, and the surface layer effectively prevents water droplets and liquid penetration.
