Stainless Steel Welded Pipe ASTM A312 TP317L Chemical Equipment Heat resistance
What is ASTM A312 TP317L Welded Pipe?
The main components of ASTM A312 TP317L welded pipe are chromium， nickel， molybdenum and titanium. The chromium content is 18-20%， nickel content is 11-15%， molybdenum content is 3-4% and titanium content is 0.10-0.25%. In addition， it also contains small amounts of niobium and vanadium and other elements.
They have good corrosion resistance， especially for sulfuric acid， acidic solution and chloride medium with excellent corrosion resistance. It can be widely used in chemical， petroleum， pharmaceutical， food processing and other fields.
It has good welding properties and can be joined by conventional welding methods. Common welding methods include TIG (TIG welding)， MIG (gas shielded welding)， etc.
