This standard covers the gas and arc welding of butt@ fillet@ and socket welds in carbon and low-alloy steel piping used in the compression@ pumping@ and transmission of crude petroleum@ petroleum products@ fuel gases@ carbon dioxide@ nitrogen and@ where applicable@ covers welding on distribution systems. It applies to both new construction and in-service welding. The welding may be done by a shielded metal-arc welding@ submerged arc welding@ gas tungsten-arc welding@ gas metal-arc welding@ flux-cored arc welding@ plasma arc welding@ oxyacetylene welding@ or flash butt welding process or by a combination of these processes using a manual@ semiautomatic@ mechanized@ or automatic welding technique or a combination of these techniques. The welds may be produced by position or roll welding or by a combination of position and roll welding. This standard also covers the procedures for radiographic@ magnetic particle@ liquid penetrant@ and ultrasonic testing@ as well as the acceptance standards to be applied to production welds tested to destruction or inspected by radiographic@ magnetic particle@ liquid penetrant@ ultrasonic@ and visual testing methods. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Each system is to be used independently of the other@ without combining values in any way. Processes other than those described above will be considered for inclusion in this standard. Persons who wish to have other processes included shall submit@ as a minimum@ the following information for the committee's consideration: a. A description of the welding process. b. A proposal on the essential variables. c. A welding procedure specification. d. Weld inspection methods. e. Types of weld imperfections and their proposed acceptance limits. f. Repair procedures. It is intended that all work performed in accordance with this standard shall meet or exceed the requirements of this standard.
