Pronto DSTM A420 pipe

Pronto DSTM A420 pipe is a standard specification for seamless carbon steel tubes for use at high temperatures. The most common use in refineries and plants when gases or fluids transported at high temperatures and pressures. Jna traders supply Pronto DSTM A420 pipe and supplies a full range of classes B / C in the amount of anger NPS 1/8 “to NPS 48”, with a nominal (average) thickness of the wall. Having clauses OTHER dimensions Pipe may the BE furnished Provided such pipe Complies with all OTHER ‘requirements of the this specification. Pipe ordered within this specification shall be suitable for bending for flanging, welding and similar operations forming. Full spectrum Pronto DSTM A420 pipe storage available in the lists 10 through 160, STD, XS, XXS. Unscheduled available wall thickness up to 4 inches.

Testing requirements for seamless A106 carbon steel pipe
hydrostatic test: pressure inspection test produces tension in the tube wall equivalent to 60% of a specified minimum yield strength (SMYS) at space. The maximum pressure does not exceed the 2,500 pounds per square inch for NPS 3 and under, and 2,800 pounds per square inch for larger sizes. The pressure is maintained for at least 5 seconds.
Mechanical testing:
tensile test: Either transverse or longitudinal approach to NPS 8 or
Tensile less size than NPS 8: Longitudinal testing only
the reduction of the Test: NPS 2 and a
bending test (cold): NPS 2 and under
