(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
ABSTRACT
This specification covers standard requirements for electric-fusion-welded steel pipe with filler metal added, for atmospheric and lower temperatures. The steel pipe shall be fabricated from a pressure vessel quality plate of various analysis and strength levels. Several grades and classes of pipe shall be provided. Grade shall designate the type of plate used while class shall designate the type of heat treatment performed during pipe manufacture. Class shall be designated as to whether the weld is radiographically examined, and as to whether the pipe is pressure tested. Steel samples shall undergo tension and transverse guided weld bend tests and conform to the specified mechanical requirements..
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. [400 mm] in outside diameter or larger and of 1/4 in. [6 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 PipeRadiography, see SectionPressure Test, see: 10nonenonenone 11none9none 12none98.3 13nonenone8.3 20stress relieved, see 5.3.1nonenone 21stress relieved, see 5.3.19none 22stress relieved, see 5.3.198.3 23stress relieved, see 5.3.1none8.3 30normalized, see 5.3.2nonenone 31normalized, see 5.3.29none 32normalized, see 5.3.298.3 33normalized, see 5.3.2none8.3 40normalized and tempered, see 5.3.3 nonenone 41normalized and tempered, see 5.3.39 none 42normalized and tempered, see 5.3.3 9 8.3 43normalized and tempered, see 5.3.3 none 8.3 50quenched and tempered, see 5.3.4 none none 51quenched and tempered, see 5.3.4 9none 52quenched and tempered, see 5.3.49 8.3 53quenched and tempered, see 5.3.4none 8.3 60normalized and precipitation heat treated nonenone 61normalized and precipitation heat treated 9 none 62normalized and precipitation heat treated 9 8.3 63normalized and precipitation heat treated none8.3 70 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 8.3
Note 1—Selection of materials should be made with attention to temperature of service. For such guidance, Specification A20/A20M may be consulted.
1.4 The values stated in either SI units or inch-pound 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 non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
