ActiveCorrosion resistant alloy clad or lined steel pipe for petroleum and natural gas industries
石油天然气工业用内覆或衬里耐腐蚀合金复合钢管
Application Summary AI generated
This standard specifies the technical requirements, dimensions, testing methods, and acceptance criteria for corrosion resistant alloy clad or lined steel pipes used in the petroleum and natural gas industries. It is applied in the construction of pipelines for transporting corrosive media such as sour gas, crude oil, or produced water, where the inner alloy layer provides protection against corrosion while the outer carbon steel ensures structural strength. The standard is primarily used by pipeline manufacturers, engineering contractors, and operators for procurement, quality control, and installation in upstream oil and gas fields or midstream transportation systems.
