ASTM A1006/A1006M-00
(Specification)Standard Specification for Steel Line Pipe, Black, Plain End, Laser Beam Welded
Standard Specification for Steel Line Pipe, Black, Plain End, Laser Beam Welded
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 , 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.
The following precautionary statement pertains to the test method portion, Section , 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.
