Bright Annealed Tubes Description

Bright annealed stainless steel tube is a kind of high precision steel tube material after finishing or cold rolling. Due to the advantages of no oxide layer both inside and outside wall, no leakage under high pressure, high precision, high finish degree, no deformation and flaring, no cracks flattening, precision bright annealed tube is mainly used to produce pneumatic or hydraulic components, such as air cylinder or gas cylinder. It can be seamless tube, and also welded pipe. The chemical components of precision bright annealed tube are C, Si, Mn, S, P, Cr.

bright annealed tube can be used for industries like automobile, and mechanical parts which have higher requirements for steel pipe precision and surface finish. Bright annealed stainless steel tubes are not only for higher precision and finish requirements, its tolerance can be maintained in 0.02-0.08mm, so many mechanical processing users gradually replace seamless steel tube or round steel with precision bright annealed tube in order to save labor, material, and time.

The traditional bright annealing furnace for stainless steel tubes is performed in a so referred to as open furnace, where the atmospheric oxygen reasons scaling of the heat treated materials, which makes the surface rough. HUASHANG STEEL has developed a one of a kind bright annealing process, the heat treatment is carried out in a so-called closed furnace. The warmth handled materials is covered by means of an inter-fuel atmosphere, which ensures the oxygen cant enter the furnace or come in to contact with the substances and react to shape scale on or tarnish the materials. The surface end is clean, bright and precision, which is a top-notch beginning point for a similar system, like electro-polishing and mechanical polishing.

Especially for the tube with size greater than 12 meters, the ordinary pickling tube is very hard to clean the internal surface, however, with the bright annealing of stainless steel method, our tubing is much cleaner, smoother on both inner and outer surface. We use bright annealing method, the temperature of the furnace can reach greater than 1350℃, and the tolerance for the putting and real temperature can be controlled Within ±2℃, which is not possible for the regular annealing.

To ensure the quality, all tubes are done 100% PMI, 100% Hydraulic test, 100% inner cleaned by sponge,100% dimension test, and 100% surface test. What is more, our quality of precision drawn tubing is same to precision rolling but has more advantage on price?  We are using the advanced cold drawn technology from Japan and Korean, making the close dimension controls. Huashang steel tubing used for instrument tubing, chromatography tubing, hydraulic tubing, high-pressure tubing, cleaned tubing, multi-core tubing.

FACTORS AFFECTING BRIGHT ANNEALING OF STAINLESS STEEL TUBES

Stainless steel tube is now widely used in the market, it has a very important role in many industries. To reduce hardness and improve plasticity; to refine the grain and eliminate the internal stress, annealing must be carried out. Stainless steel tube annealing is generally carried out by continuous bright annealing furnace with ammonia decomposition protection gas for annealing of intermediate state and finished products. It can protect the bright outer surface of the stainless steel tube very well. The finished tube after annealing is also bright. This kind of tube does not need pickling.

There are many influence factors of bright annealed stainless steel tubing, this article lists five important factors for your reference.

1. Whether the annealing temperature reaches the specified temperature

The heat treatment of stainless steel is usually solid solution heat treatment, that is what people usually called annealing, the temperature range of 1040~1120 (Japanese standard).  You can also look through the observation hole of the annealing furnace, the stainless steel tube in the annealing surface should be in incandescent state, but no softening droop appears.

2. Annealing atmosphere

Pure hydrogen is regarded as anneal atmosphere commonly, atmosphere purity had better be 99.99% above, if another part in atmosphere is inert gas, purity also can a bit lower, but it  absolutely cannot contain excessive oxygen water vapor.

3. Bright annealing furnace should be closed and isolated from the outside air; using hydrogen as a shielding gas, only one vent is vented (used to ignite the exhausted hydrogen). It can be checked by wiping in the annealing furnace with soap water in the joint gap to see whether the air run, one of the most likely places for gas to escape is where the annealing furnace enters the pipe and where the pipe comes out. The sealing ring in this place is particularly prone to wear and tear, so it should be checked and changed frequently.

4. Protect gas pressure

In order to prevent micro-leakage, the protective gas in the furnace should maintain a certain positive pressure, if it is hydrogen protective gas, the general requirements of more than 20kBar.

5. On the one hand, check whether the furnace material is dry, furnace material must be dried for the first furnace charging, Secondly, whether the stainless steel tube into the furnace remains too much water, especially if there are holes in the pipe, do not leak into it, or it will destroy the atmosphere of the stove.

That's basically what you need to pay attention to. Usually, after the furnace should be back about 20 meters of stainless steel tube will start to shine. Huashang Steel has stock for bright annealed stainless steel tube, welcome to inquiry and order.

THE TECHNOLOGY EXPLAINATION OF BRIGHT ANNEALED STAINLESS STEEL TUBING

Bright annealing equipment is a special equipment which is used to heat the stainless steel tube online to 1050 and then to cool it below 100 rapidly under the protection of hydrogen. The induction heating coil and cooling system are built into the sealed tube. The main feature of the system is the use of non-reusing hydrogen, with a very small flow rate, and only a few liters of pure hydrogen per minute. The gas used is pure hydrogen, which is not dangerous because of its small amount in the gas pipeline. At the same time, the exhaust gas discharged is burned, which can prevent the hydrogen from diffusing into the surrounding air and thus avoid the accumulation of dangerous concentration in the surrounding space. The heated stainless steel tube is cooled by heat conduction in a special closed cooling tunnel. These characteristics are the reasons why this system only needs a small amount of gas for bright annealing compared with other systems. Gas control system and equipment protection are automatically controlled by PLC. So ensure the high reliability and safety of equipment if power supply using the latest IGBT inverter power supply, its output frequency can be applied to all pipe diameters. This is how bright annealed stainless steel tubing works.

Stainless Steel Tubing Materials

FUTURE AND PROMOTION OF STAINLESS STEEL TUBE

Stainless steel is recognized as a kind of health material that can be implanted into human body. It has been used successfully for many years in developed countries to produce water pipes. It has become the world trend and development direction. Stainless steel pipes are called "the real green pipes of the 21st century".

Thin-walled stainless steel pipes, which began to be produced and used in China in the late 1990s, are a new generation emerging in the field of pipe materials, and have been widely used in building water supply and direct drinking water pipelines.

The durability of thin-walled stainless steel pipes has been recognized by engineering circles, and related parties are starting from reducing wall thickness and price in order to facilitate further promotion. Especially, the small bore stainless steel tube is not high, so the matching connection method, the reliability and price of pipe fittings are the main factors determining its development. Developers have independently developed connection technology and pipe fittings all over the country, which is a promising pipe material. The Ministry of Construction and relevant departments also attach great importance to this new type of pipe. The popularization and application of thin-walled stainless steel pipe technology and products are of great significance for improving the grade of modern Chinese architecture and ensuring the quality of water supply.

Stainless steel pipe will not cause environmental pollution. It is environmentally friendly. It is conducive to sustainable development. And stainless steel scrap also has great economic value. Stainless steel materials are safe, non-toxic, non-corrosive and exudates, no odor or turbidity problems, and will not cause secondary pollution to water quality, maintain the purity and hygiene of water quality, and ensure the safety of health. It is helpful to improve the grade of urban buildings. It can be used either in open or in concealment, or in burial.

APPLICATION PROSPECT OF STAINLESS STEEL TUBING

Stainless steel pipes are safe, reliable, hygienic, environmentally friendly, economical and applicable. The successful development of thin-walled pipes and new reliable, simple and convenient connection methods makes them have more irreplaceable advantages than other pipes. Its application in engineering will be more and more extensive, and its application will be more and more popular, and its prospect is promising.

With the implementation of China's reform and opening-up policy, the national economy has been growing rapidly, and a large number of urban residential buildings, public buildings and tourist facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. Especially the problem of water quality, people pay more and more attention to it, and the requirements are constantly improved. Stainless steel tubing manufacturers have seized this requirement and made stainless steel to solve the problem of improving water quality.

Galvanized steel pipe, a common pipe material, will gradually withdraw from the historical stage under the influence of relevant national policies because of its corrosion resistance. Plastic pipes, composite pipes and copper pipes are commonly used in pipeline systems. But in many cases, stainless steel pipes have more advantages, especially thin-walled stainless steel pipes whose wall thickness is only 0.6-1.2 mm. In high-quality drinking water system, hot water system and water supply system, safety and hygiene are the first priority.

Affected by China's economic slowdown, there is  low demand for hexagon steel tube commodities. Clarkson Plc, the world's largest shipping consultancy, had forecast China's steel imports would rise 6% in 2016, down from 8.7% in 2015. The BDI decline partly reflects the risk of deflation in China, while industries such as shipping and steel will be hit hard. Learned from the Hangzhou market today, although the upstream raw materials in recent days rose a lot, factory price has also been raised, but the market volume is insufficient, the downstream has been insensitive to the price, and the majority of wait-and-see, traders are not optimistic about the market trend, there is no plan to adjust prices.

Market interpretation: perhaps the current BDI slump is just a prelude to the commodities, including the entire economic recession will bring iron ore into the abyss once again, Don't think that $40 or more is bad enough right now, with the giants doggedly ramping up production, Fu MaoGe drunkenly said don't worry that the hard days for hexagon steel tube market is still ahead .

In order to ensure the corrosion resistance of the stainless steel capillary, it is necessary to select a steel containing more than 12% chromium when selecting the steel.

The capillary tube is applied to many industries such as chemical, petroleum, electronics, medical, aerospace, air conditioning, medical equipment, pharmaceutical, boiler, and other fields. Also, there are a lot of products like injection needle tube, puncture needle tube, beauty needle tube, temperature sensor tube, thermometer tube, thermostat tube, etc.

Bright Annealed Tubes Description

The traditional annealing approach is performed in a so referred to as open furnace, where the atmospheric oxygen reasons scaling of the heat treated materials, which makes the surface rough. HUASHANG STEEL has developed a one of a kind bright annealing process, the heat treatment is carried out in a so-called clsoed furnace. The warmth handled materials is covered by means of an inter-fuel atmosphere, which ensures the oxygen cant enter the furance or come in to contact with the substances and react to shape scale on or tarnish the materials. The surfaceend is clean, bright and precision, which is a top-notch beginning point for similarly system, like electro-polishing and mechanical polishing.

Especially for the tube with size greater than 12 meters, the ordinary pickling tube is very hard to clean the internal surface, however, with the bright annealing method,  our tubing is much cleaner, smoother on both inner and outer surface. We use bright annealing method, the temperature of furnace can reach greater than 1350℃, and the tolerance for the putting and real temperature can be controlled Within ±2℃, which is not possible for the regular annealing To ensure the quality, all tubes are done 100% PMI, 100% Hydraulic test, 100% inner cleaned by sponge, 100% dimension test, and 100% surface test.

What is more, our quality of precision drawn tubing is same to precision rolling but has more advantage on price?  We are using the advanced cold drawn technology from Japan and Korean, making the close dimension controls Huashang steel tubing used for instrument tubing, chromatography tubing, hydraulic tubing, high-pressure tubing, cleaned tubing, multi-core tubing. Type of tubes is welded tubing and seamless tubing.

HUASHANG uses the most advanced technology-the floating plug drawing technology, and the most environmentally friendly process-Bright annealed Process to make quality tubing.

Stainless Steel Tubing Materials

For different applications, we offer sevsral materials such as austenitic stainless steel, duplex & super duplex steel, nickel alloly steel etc. And these tubes consist of seamless tubing & welded tubing. Welded stainless steel tube steel can be bent and cut to required shape and length. It is telescopic with adjacent sizes, and ideal for use in day-to-day pipe work, as well as for bushings, spacers, guide tubes, standoffs, and bearings.

304 Stainless Steel Is the most versatile and extensively used of stainless metal grades, due to its combination of corrosion resistance, formability, and ductility. 316 Stainless Steel provides the first-class resistance to pitting and corrosion of any of the austenitic (300 series) stainless steels. It is extremely ductile, with remarkable electricity at improved temperatures. Seamless tubing can be produced with heavier wall thicknesses for mechanical applications. It is best for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments.
