从China供应商批发进口4inch 101.60mm Tubing Pipe N80/R2 (Api-5ct) — FOB条款

The 4inch 101.60mm Tubing Pipe in N80/R2 grade is a seamless carbon steel OCTG product engineered for oil and gas extraction, conforming to API-5CT standards. It is designed to withstand high-pressure downhole environments, with the N80 grade offering a yield strength of 552 MPa typical for this classification. The 101.60mm outer diameter corresponds to a 4-inch nominal size, a standard dimension in oilfield applications for both vertical and directional drilling.

This tubing pipe is manufactured from carbon steel with a typical wall thickness range of 4.83mm to 6.35mm for 4-inch variants, providing the necessary burst and collapse resistance for deep well operations. The R2 designation indicates a premium connection type, offering enhanced hydraulic efficiency and thread compound compatibility. Standard surface finishes include bare or coated options, with phosphating or varnishing applied to prevent corrosion during storage and transit.

Primarily used in onshore and offshore drilling rigs, this tubing is sourced by EPC contractors, oilfield service companies and exploration firms for production casing and well completion. It is typically supplied in lengths of 8 to 12 meters, with both ends threaded and coupled. Buyers should confirm thread type, end finish and third-party inspection requirements, as these vary by project specification.
