Covers recommended maintenance welding practices that may be used when repairing or installing appurtenances on pipeline systems that are or have been in service in the compression , pumping, and transmission of crude petroleum, petroleum products, and fuel gases. It is also intended to apply, where applicable, when making repairs to the distribution piping systems for these products. The welding may be done by shielded metal-arc welding, gas tungsten- arc welding, gas metal- arc welding,flux-cored arc welding, or oxyacetylene welding using a manual or semiautomatic welding technique or a combination of the techniques.
