(Specification)Standard Specification for Steel Line Pipe, Black, Plain-End, Electric-Resistance-Welded (Withdrawn 2014)
Standard Specification for Steel Line Pipe, Black, Plain-End, Electric-Resistance-Welded (Withdrawn 2014)
ABSTRACT
This specification covers electric-resistance-welded, black, plain-end, steel pipe for use in the conveyance of fluids under pressure. It is intended that the pipe be capable of being circumferentially welded in the field when welding procedures in accordance with the requirements of the applicable pipeline construction code are used. The required chemical compositions for the steel material are presented. Different mechanical test requirements are presented which includes, tension test, and flattening test. Also, each length of pipe shall be subjected to the hydrostatic test without leakage through the weld seam or the pipe body. Finally, the weld seam of each length of pipe shall be inspected using a non-destructive electric test method.
SCOPE
1.1 This specification covers electric-resistance-welded, black, plain-end, steel pipe for use in the conveyance of fluids under pressure. Pipe in sizes NPS 1 to 26, inclusive, with nominal wall thickness 0.750 in. [19.1 mm] or less, as given in ASME B36.10M is included. Pipe having other dimensions, in this size range, may be furnished provided such pipe complies with all other requirements of this specification.
1.2 It is intended that the pipe be capable of being circumferentially welded in the field when welding procedures in accordance with the requirements of the applicable pipeline construction code are used.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.
WITHDRAWN RATIONALE
This specification covered electric-resistance-welded, black, plain-end, steel pipe for use in the conveyance of fluids under pressure. Pipe in sizes NPS 1 to 26, inclusive, with nominal wall thickness 0.750 in. [19.1 mm] or less, as given in ASME B36.10M were included. Pipe having other dimensions, in this size range, may have been furnished provided such pipe complied with all other requirements of this specification.
Formerly under the jurisdiction of Committee A01 on Steel, Stainless Steel and Related Alloys, this specification was withdrawn in March 2014. This standard is being withdrawn without replacement due to its limited use by industry.
