(Specification)Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures
Standard Specification for Electric-Fusion-Welded Steel Pipe for Atmospheric and Lower Temperatures
SCOPE
1.1 This specification covers electric-fusion-welded steel pipe with filler metal added, fabricated from pressure vessel quality plate of several analyses and strength levels and suitable for high-pressure service at atmospheric and lower temperatures. Heat treatment may or may not be required to attain the desired properties or to comply with applicable code requirements. Supplementary requirements are provided for use when additional testing or examination is desired.
1.2 The specification nominally covers pipe 16 in. (405 mm) in outside diameter or larger and of 1/ 4 in. (6.4 mm) wall thickness or greater. Pipe having other dimensions may be furnished provided it complies with all other requirements of this specification.
1.3 Several grades and classes of pipe are provided.
1.3.1 Grade designates the type of plate used as listed in 5.1.
1.3.2 Class designates the type of heat treatment performed during manufacture of the pipe, whether the weld is radiographically examined, and whether the pipe has been pressure tested as listed in 1.3.3.
1.3.3 Class designations are as follows (Note 1):ClassHeat Treatment on Pipe Radiography, see SectionPressure Test, see:10none nonenone11none9none12none98.313none none8.320stress relieved, see 5.3.1nonenone21stress relieved, see 5.3.19none22stress relieved, see 5.3.198.323stress relieved, see 5.3.1none8.330normalized, see 5.3.2nonenone31normalized, see 5.3.29none32normalized, see 5.3.298.333normalized, see 5.3.2none8.340normalized and tempered, see 5.3.3 none none 41normalized and tempered, see 5.3.39none42normalized and tempered, see 5.3.398.343normalized and tempered, see 5.3.3 none 8.350quenched and tempered, see 5.3.4 none none51quenched and tempered, see 5.3.4 9none52quenched and tempered, see 5.3.498.353quenched and tempered, see 5.3.4none 8.360normalized and precipitation heat treatednonenone 61normalized and precipitation heat treated9 none 62normalized and precipitation heat treated9 8.3 63normalized and precipitation heat treatednone8.370 quenched and precipitation heat treatednone none 71 quenched and precipitation heat treated9 none 72quenched and precipitation heat treated98.3 73 quenched and precipitation heat treatednone 8.3Note 1—Selection of materials should be made with attention to temperature of service.
