This guide covers standard specification for straight seam or spinal seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. The sizes covered shall include NPS 14 to 30 with extra light (Schedule 5S) and light (Schedule 10S) wall thickness. Several grades of alloy steel shall be covered and shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, titanium, columbium, cerium, and other elements. The chemical composition of the welding filler metal shall also conform to the requirements of the applicable AWS specification for the corresponding grade. Tensile properties of the plate or sheet used in making the pipe shall conform to the prescribed values of tensile strength and yield strength. Mechanical tests such as tension test and transverse guided-bend weld test shall be conducted. Pressure or nondestructive electric test shall also be performed.

Область применения

1.1 This specification covers straight seam or spiral seam electric-fusion-welded, light-wall, austenitic chromium-nickel alloy steel pipe for corrosive or high-temperature service. The sizes covered are NPS 14 to 30 with extra light (Schedule 5S) and light (Schedule 10S) wall thicknesses. Table shows the wall thickness of Schedule 5S and 10S pipe. Pipe having other dimensions may be furnished provided such pipe complies with all other requirements of this specification.

1.2 Several grades of alloy steel are covered as indicated in Table 1.

1.3 Optional supplementary requirements are provided. These call for additional tests to be made, and when desired shall be stated in the order, together with the number of such tests required.

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

Note 1—The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as nominal diameter, size, and nominal size.
