(Specification)Specification for Electric-Resistance-Welded Carbon Steel Boiler Superheater Tubes for High-Pressure Service (Withdrawn 1997)
Specification for Electric-Resistance-Welded Carbon Steel Boiler Superheater Tubes for High-Pressure Service (Withdrawn 1997)
SCOPE
1.1 This specification covers minimum-wall-thickness, electric-resistance-welded, carbon steel, boiler and superheater tubes for high-pressure service.
1.2 The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.085 to 0.360 in. [2.2 to 9.1 mm] inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.
1.4 When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of Specification A520 shall supplement and supersede the requirements of this specification.
1.5 An optional supplementary requirement is provided and, when desired, shall be so stated in the order.
1.6 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 are not exact equivalents; therefore, each system must 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.
