Corrosion-resistant alloy compound elbow for oil and gas industry

1 Scope

This standard stipulates that the oil and gas industry pipeline transportation system uses the nominal diameter DN150~DN800 and the bending radius R≥5D to resist corrosion. Design, geometry, materials, manufacturing processes, technical requirements and inspection methods, NDT, surface quality and defect repair of etched alloy composite elbows, Basic requirements for signs, transportation and protection. This standard applies to the transportation pipelines in the oil and gas industry and the process pipelines to transport oil and natural gas containing corrosive media. Corrosion-resistant alloy composite elbows for single-phase or multi-phase fluids such as water, and other fields can also be used.
