What is ASME SA312 TP316L material pipe?

What is ASME SA312 TP316L material pipe?

ASME SA312:

This is a standard specification from the American Society of Mechanical Engineers (ASME) that covers seamless, welded, and heavily cold-worked austenitic stainless steel pipes.

TP316L:

This refers to the specific grade of stainless steel. It is a low-carbon version of the 316 grade, which contains molybdenum, enhancing its resistance to pitting and crevice corrosion in chloride-containing environments like saltwater.

Seamless and Welded:

ASME SA312 TP316L pipes can be produced in both seamless and welded forms. Seamless pipes are manufactured by piercing a solid steel billet, while welded pipes are made by rolling and welding strips or sheets of steel.
