ASME SA 178 welded carbon steel tubes

SA-178/SA-178M ASME BPVC.II/a-2015

Specification for electric-resistance-welded carbon steel and carbon-manganese steel boiler and super heater tubes

This specification covers minimum-wall-thickness electric-resistance-welded tubes made of carbon steel and cabon-manganese steel intended for use as boiler tubes, boiler flues, super heater flues, and safe ends.

Ordering Information:
1.Orders for material under this specification should include the following, as required, to describe the desired material adequately: Quantity, name of material( electric-resistance-welded tubes). Grade (A, C, or D). Size, Length, Optional requirements (product analysis, crush test, hydrostatic or nondestructive electric test.) Test report required ( Certification section of specification A450/A450M), specification, and designation, individual supplementary requirements, if required and special requirements.
