1.1 This specification covers double submerged-arc welded, black, plain end steel pipe for use in the conveyance of fluids under pressure. Pipe in sizes NPS 16 and larger, as given in ASME B36.10, are included; pipe having other dimensions, in this size range, are permitted, provided such pipe complies with all other requirements of this specification.

1.2 It is intended that pipe be capable of being 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. 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 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.
