2、he year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()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 conveyance of fluids under
3、pressure.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.1.2 It is intended that the p
4、ipe 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 standard.Within the text,the
5、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,of this specification.Thisstandar
