Standard Specification for Steel Line Pipe, Black, Plain End, Laser Beam Welded (Withdrawn 2014)

ABSTRACT
This specification covers the standard requirements for laser beam welded, black plain end steel pipe for use in the conveyance of fluids under pressure. Dimensions and weight [mass] per unit length of pipes with designated NPS sizes and specified nominal wall thickness shall be given. Heat and product analysis shall be performed wherein steel shall conform to the required chemical composition for carbon, sulfur, and phosphorus. The steel shall conform to the required tensile properties such as minimum and maximum yield strength. The following tests shall be conducted, namely: Charpy V-notch test; weld ductility test; and hydrostatic test.
SCOPE
1.1 This specification covers laser beam 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 Table 1, 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 inch-pound units or in SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values in each system are not exact equivalents: therefore, each system is to be used independently of the other, without combining values in any way.
1.4 The following precautionary statement pertains to the test method portion, Section 14, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This specification covered laser beam 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 were included. Pipe having other dimensions, in this size range, may have been furnished provided such pipe complied with all other requirements of the specification.
Formerly under the jurisdiction of Committee A01 on Steel, Stainless Steel and Related Alloys, this specification was withdrawn in October 2014. This standard is being withdrawn without replacement due to its limited use by industry.
