What are ASTM A269 Stainless Steel Pressure Vessel Pipes?
ASTM A269 is a general standard developed by the American Society for Testing and Materials (ASTM) that covers seamless and welded stainless steel tubes. It specifies the chemical composition, mechanical properties, manufacturing processes, and testing requirements for stainless steel pipes. When pipes manufactured under this standard are used in pressure vessel systems, they are referred to as ASTM A269 stainless steel pressure vessel pipes.
These pipes are made from corrosion-resistant stainless steel grades such as 304, 304L, 316, and 316L, and are primarily used for fluid transport applications that require withstanding internal or external pressure while meeting higher safety and reliability standards-such as gas and liquid pipelines.
