This specification covers double submerged-arc welded, black, plain end steel pipes for use in the conveyance of fluids under pressure. The pipes shall be capable of being welded in the field. Skelp widths for helical seam pipe shall be neither less than 0.8 nor more than 3.0 times the pipe's specified outside diameter. Skelp end welds shall not be permitted in finished pipe, except for helical seam pipe having its skelp end welds manufactured by double submerged-arc welding. For such pipes, skelp ends shall have been properly prepared for welding. The specimens shall undergo the following tests: tension test, guided bend test, Charpy V-notch test, and hydrostatic test. After hydrostatic test, nondestructive examinations by ultrasonic inspection shall be done.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

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.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
