A403 WP304 90 Degree Pipe Fittings Seamless Elbow

Stainless steel 90 degree elbow and is one type of steel pipe fittings which is produced by steel rod and pipes, the manufacturing standard are ASME B16.9 and ASME B16.11. They are mostly used for pressure piping applications. Our stainless steel pipe fittings limit types of localized

corrosion and are indispensable to applicatons requiring compact but flexible seals. Restraining deformities and cracks under high temperatures.

Type of Stainless Steel Bends Elbows

Stainless steel butt welding elbows can be into seamless and ERW pipe fittings, seamless elbow fittings are made from seamless steel pipes, ERW elbow fittings are made by ERW steel pipes while welded large diameter fittings are produced by steel plates.Both of them are manufactured according to ASME B16.9.
Forged stainless steel elbow can be divided into socket weld elbow and threaded pipe elbow, both types are forged by steel rod which according to ASME B16.11

Seamless elbows are used to change the direction of pipes in a piping system.

45° elbows and 90° elbows and 180° elbows are the most commonly used. According to engineering needs, they also include 60° elbows and other illegal angles. Two 45-degree elbows cannot be welded into a 90-degree elbow. Because the stress concentration area is the elbow, the expansion and most of the stress and deformation during the cooling process will be released at the elbow. In addition, the weld itself is a weak link. Fatigue deformation will quickly cause cracking and damage, which will bury many hidden dangers. Therefore, if it is not used immediately, it will eventually lead to huge losses.
