90 Degree Elbow, buy ANSI B16.9 Long Radius 90 Degree Butt Welding Elbow on China Suppliers Mobile

Product Details

Welding elbow pipe technical requirements are the following: geometric dimensions, including diameter, diameter, wall thickness. It is also required to control the radius of curvature. Such as a radius of 1.5D, then the radius of curvature must be within the required tolerance. As most of these pipes for welding, in order to improve the quality of welding, the end of the car into a groove, leaving a certain angle, with a certain side, this requirement is also more stringent, more thick side, the angle of the number and deviation range Have provisions, geometric size than the tube more than a lot of items. Surface quality and mechanical properties of the basic and the tube is the same. In order to facilitate the welding, and connected to the steel pipe is the same.

High-quality products

Seamless Carbon Steel Elbow is to change the direction of the pipe in the piping system. 45 °elbow and 90 °elbow 180 °elbow three kind most commonly used, according to project needs, also include 60 °bend and other non-normal angles.Two 45-degree elbows can not be welded into a 90-degree bend to use, because the stress concentration area is the elbow pipe, expansion and most of the stress deformation during cooling are released at the elbow. Also weld itself to be the weak link, fatigue deformation will soon cause cracking damage, which planted a lot of hidden dangers, so do not at immediate convenience, eventually leading to huge losses.
