What is the difference between B36.10 and B36.19?
As outlined, B36.10 relates to the standards of wrought steel and carbon steel piping system components, and B36.19 relates to Stainless steel piping system components. At certain sizes, B36.19 differs in wall thickness and weight from B36.10 and hence it matters if you specify Pipe and piping system components to B36.10 or B36.19.
