Covers metal-arc-welded steel pipe for use with high pressure transmission systems. The pipe is intended for fabrication of fittings and accessories for compressor or pump -station piping. The required chemical composition for carbon steel, and the tensile properties of finished pipes are presented. Mechanical testing requirements namely transverse body tension test and transverse weld tension test shall be performed on each length of pipe from each lot of lengths, and transverse guided- bend weld test cut from a length of pipe from each lot of 50 length, also hydrostatic test from each length of pipes shall be performed.

Historical Version s - view previous versions of standard. More A This specification covers metal-arc-welded steel pipe for use with high pressure transmission systems. The pipe is intended for fabrication of fittings and accessories for compressor or pump-station piping.
The required chemical compositions for carbon steel, and the tensile properties of finished pipes are presented. Mechanical testing requirements namely transverse body tension test and transverse weld tension test shall be performed on each length of pipe from each lot of lengths, and transverse guided-bend weld test cut from a length of pipe from each lot of 50 length, also hydrostatic test from each length of pipes shall be performed.
A radiographic examination shall also be performed to ensure that the welding equipment is consistently producing the required quality. 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. Pipe ordered to this specification shall be suitable for bending, flanging, corrugating, and similar operations.
For some sizes of the pipe covered by this specification, it becomes expedient to use manual welding, in which case the provisions of Note 3 shall be followed. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Combining values from the two systems may result in nonconformance with the standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
