ASME B36.19M

Generally speaking, ASME B36.19M prescribed the weights & dimensions of welded and seamless wrought stainless steel pipe for high or low temperatures and pressures. It covers pipes sized from NPS 1/8(DN 6) through NPS 30(DN 750) with four basic wall-thickness designations: SCH 5S, SCH 10S, SCH 40S, SCH 80S. The suffix “S” in the schedule number is used to differentiate B36.19M pipe from B36.10M pipe. The pipe may be either manufactured to ISO metric unit or US Customary unit. The pipe may be furnished with threaded ends, plain ends, or beveled ends.

Materials

The ASME B36.19M seamless or welded pipe shall be be made from (but not limited to) various stainless steel materials covering ferritic stainless steel, austenitic stainless steel, martensitic stainless steel, precipitation-hardening stainless steel, and duplex stainless steel. Moreover, the material range can be extended to titanium & titanium alloy, zirconium & zirconium alloy, nickel & nickel alloy, copper & copper alloy, aluminum & aluminum alloy, etc.

Weight Calculation

The nominal weight of the pipe can be calculated using the following formula:

  • US Customary Unit: Wa = 10.69(D – t)t; Metric Unit: Wb = 0.0246615(D – t)t.
  • Wa: lb/ft, Wb: kg/m; D: O.D of pipe(inch or mm); t: wall thickness(inch or mm).
  • This formula is based on stainless steels. It is not applicable for other materials with variable density.
