In selection of bolting material for heat exchanger in service environment. We generally use SA193-B7M&SA194-2HM instead of SA193-B7&SA194-2H.
I would like to know why SA193-B7M&SA194-2HM is preferred.
Thank you.
I can see many times following sentence in project spec.
"Pipe used for pressure containing components shall be seamless"
Can I regard "pressure containing components" as " pressure part"? Please advise.
Thank you.
