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.

Before importing 13CR casing pipe from Tianjin Grand Victory Petroleum Equipment, verify the supplier's API 5CT licensing status and request a sample Mill Test Certificate for review. Confirm the exact production lead time for your order quantity, as martensitic stainless steel OCTG may have longer manufacturing cycles than standard grades. Clarify the total landed cost, including any import duties, taxes, and local port handling charges for your destination country.
Logistics for 7-inch casing require careful planning. Pipes are typically shipped in bundles on flat-rack containers or as breakbulk cargo on vessels. Discuss with the supplier the packaging method to prevent damage during transit and the exact shipping terms (FOB, CIF, etc.). Confirm the port of loading in Tianjin and the available vessel schedules to your destination port. Lead times from order confirmation to shipment can vary significantly and must be explicitly agreed upon.
For quality assurance upon receipt, consider appointing a third-party inspection agency to witness the loading at the mill or port. They can verify the markings, dimensions, and packaging against the purchase order and MTC. Once on-site, store the casing on level ground with adequate support to prevent bending. Before running into the well, conduct a visual inspection of threads and couplings and verify the pipe tally against the well design program.
