API Issues New Pipeline Welding Standard

The American Petroleum Institute has issued the 20th edition of API Standard 1104, Welding of Pipelines and Related Facilities. The standard covers the 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, and nitrogen. Where applicable, it also covers welding on gas distribution piping. The standard applies to both new construction and in-service welding. The Department of Transportation expects to incorporate API’s revised standard into regulation by reference into the Federal Register within the next 6-12 months.
