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.
