从China供应商批发进口13cr Casing Pipe 7 Inch 9.19mm Thickness — FOB条款

This 13CR casing pipe from Tianjin Grand Victory Petroleum Equipment is a 7-inch (177.8mm nominal) oil country tubular good with a 9.19mm wall thickness, manufactured from martensitic stainless steel to API 5CT Grade L80 13CR specification. The 13% chromium alloy composition provides inherent resistance to carbon dioxide and hydrogen sulfide corrosion, a critical property for wells with sour gas content. It is designed as a structural conduit for high-pressure petroleum and natural gas extraction, forming the primary wellbore lining after drilling.

The pipe's L80 grade designation indicates a minimum yield strength of 80,000 psi (552 MPa), typical for intermediate-depth wells. Its martensitic microstructure, achieved through heat treatment, balances strength with the corrosion resistance needed for mildly sour service environments where chloride levels are not extreme. Standard industry lengths for such casing are typically range joints of 9.6m to 11.6m, with ends prepared for threaded and coupled connections per API 5B.

Primary buyers include drilling contractors, oilfield service companies, and EPC firms sourcing OCTG for exploration and production projects in regions with corrosive well fluids, such as parts of the Middle East, Southeast Asia, and North America. Trade terms are commonly negotiated on a per-metric-ton basis, with bulk orders for entire well strings. Tianjin Grand Victory, based in China's Tianjin industrial zone, supplies this product, though specific MOQ, lead time, and pricing must be confirmed directly with them for your project requirements.
