Product description
The connection form of stainless steel 180 degree steel pipe elbow is butt welding elbow and steel pipe directly. According to its curvature radius, butt welding 180 degree elbow can be divided into long radius and short radius. Pressure grade is divided into about 17 types, which are the same as American pipe standard. The most commonly used are STD , SCH10, and SCH40. According to material, they are carbon steel, alloy steel and stainless steel.

HOW TO CALCULATE RADIUS OF STAINLESS STEEL ELBOW?
I have my own unique views on the calculation formula of stainless steel elbow size. I hope you can learn more from the following experience.
- 1.5 times the elbow center height = diameter *1.524, which is actually the diameter * multiple. Round the number after the decimal point of the result to an integer. For example, the diameter of 219 is 200, the center height is 200*1.524=304.8, and take 305. The diameter of 114 is 100, the height of the center is 100*1.524=152.4, take 152.
The algorithm applicable to DN100 and above elbow radius of curvature is convenient and fast to calculate.
- Stamp height = center height + elbow radius, such as 1.5 times the diameter of 219 elbow stamp height =305+219/2=305+109.5=414.5
- Outer arc length =(center height + radius)*3.14*2/360* degree, i.e. (stamp height)*3.14*2/360* degree, from which it can be calculated that the outer arc length of 90-degree elbow = stamp height *3.14/2.
- Internal arc length =(center height - radius)*3.14*2/360* degrees.
- Elbow length = elbow center height *3.14/2* elbow outer diameter/pipe diameter +(pipe wall thickness *3)+ machining allowance, such as using 180*8 pipe cutting, push system 273 elbow, with the above formula can be calculated, blanking length =381*1.57*273/180+24=931.22mm+ machining allowance.
