2、f revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers laser beam welded, black,plain end steel pipe for use in the convey

3、ance of fluids underpressure. Pipe in sizes NPS 1 to 26, inclusive, with nominalwall 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 otherrequirements of this specification.1.

4、2 It is intended that the pipe be capable of being circum-ferentially welded in the field when welding procedures inaccordance with the requirements of the applicable pipelineconstruction code are used.1.3 The values stated in either inch-pound units or in SIunits are to be regarded separately as st

5、andard. Within the text,the SI units are shown in brackets. The values in each systemare not exact equivalents: therefore, each system is to be usedindependently of the other, without combining values in anyway.1.4 The following precautionary statement pertains to thetest method portion, Section 14,

6、 of this specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to us
