ASTM A312 TP317L,Stainless Steel Welded Tube,Boiler,Superheater,Heat Exchanger
Overview
The ASTM A312 TP317L is a specification for welded stainless steel tubes specifically made from the alloy TP317L. This alloy is a low-carbon version of TP317, which contains higher levels of chromium, nickel, and molybdenum for enhanced corrosion resistance in high-temperature and acidic environments.The standard outlines the requirements for dimensions, mechanical properties, chemical composition, testing, and certification of the welded tubes. It ensures that the tubes meet certain quality standards and are suitable for various industrial applications, such as chemical processing, pharmaceuticals, pulp and paper, and food processing.
