ASTM A269 seamless tubing for instrument lines & fluid systems.
ASTM A269 seamless tubing for instrument lines & fluid systems.
Description
ASTM A269 is a widely used standard for seamless and welded austenitic stainless steel tubing. It sets clear requirements for tubing used in general industrial applications, especially where corrosion resistance and good performance at different temperatures are needed. This standard covers popular stainless steel grades such as 304, 316, 321, and 347. It specifies rules for chemical composition, mechanical properties, dimensional tolerances, heat treatment, and various quality tests like hydrostatic, flaring, and hardness testing. The tubing covered by ASTM A269 is commonly used in instrument lines, fluid systems, heat exchangers, and general process piping.
