ASME B16.9 mainly specifies the dimensions, tolerances, test methods of welded pipe fittings.Butt welded elbows are the most widely used type of butt welded pipe fittings.This article will introduce the stainless steel butt welded elbows.
The type of the stainless steel welded elbows by ASME B16.9.
According to the bending radius:Long radius elbows(1.5D);short radius elbows(1D);3D elbows
According to the bending angle:45degree elbows;90degree elbows;180degree elbows.
According to production methods:seamless and welded.
Long radius elbow dimension
Short radius elbow dimension
Material grade of stainless steel butt welded elbows
The material standard for ASME B16.9 standard stainless steel butt welded elbows is ASTM A403. This material standard includes various austenitic stainless steel materials such as 304/304L, 316/316L, 321, 347, and 904L. Customers can choose suitable materials basing on different pipeline usage environments.
Chemical composition
Tolerance
The ASME B16.9 standard also specifies the dimensional tolerances for stainless steel butt welded elbows, including length, wall thickness, inner diameter, outer diameter, and other aspects. The dimensional deviation must be within the tolerance range specified in the standard.
Application Scope
Stainless steel butt welded elbows are a very important component in pipeline systems. They can not only connect pipelines, but also change the flow direction of pipelines, reduce fluid resistance, and regulate flow rates. Therefore, they are widely used in industries such as chemical, food, petroleum, natural gas, and biopharmaceuticals.
