从China供应商批发进口7-5/8 Inch Ltc Connection Casing Pipe R3 — FOB条款

The 7-5/8 inch LTC connection casing pipe R3 is an API 5CT compliant product designed for oil and gas well construction, featuring a long threaded connection joint for leak resistant make up. Built from carbon steel, it is available in grades J55, N80, or L80 to meet varying downhole pressure and tensile demands. The R3 designation indicates a specific outer diameter and wall thickness combination, standard for intermediate casing strings in onshore and shallow offshore wells.

This casing pipe uses a robust carbon steel composition with typical yield strengths of 379 MPa for J55, 517 MPa for N80, and 552 MPa for L80 grades, all heat treated to standard API 5CT requirements. The LTC connection provides a gas tight seal under axial load, with a standard thread compound applied to prevent galling. Surface finishes are typically phosphated or coated for corrosion protection during storage and transit, with mill test reports provided for each heat number.

Primary buyers include drilling contractors, EPC firms, and national oil companies sourcing bulk lots for exploration and production projects. The pipe is traded in 9 to 13 meter lengths, bundled for sea freight, and quoted per metric ton on FOB Tianjin or CIF destination basis. Common packaging uses steel straps and wooden skids, with each bundle tagged for traceability. Lead times depend on mill schedules, typically 45 to 60 days for new production orders.
