ASME B36.19 specifications cover the dimensions of seamless and welded steel pipes for high and low-temperature service, providing combinations of pipe outside and inside diameter (OD, ID), pipe thickness (WT, designated in “schedule”) and pipes theoretical weights (in pounds per foot and kilogram per meter). ASME B36.19 applies to stainless steel, duplex, and nickel alloy pipes (like A312, A790, A928, B161, etc).
