4inch 101.60mm Tubing Pipe N80/R2 (API-5CT)
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.

Sourcing 4inch 101.60mm Tubing Pipe N80/R2 (API-5CT) from Tianjin Dalipu Oil Country Tubular Goods Co., Ltd - China Import Guide
Before ordering, verify the tubing’s compliance with API-5CT standards by requesting the mill test report and heat number traceability. Confirm that the N80 grade meets your project’s yield strength and corrosion resistance requirements, especially if the well environment includes sour gases. Check that the R2 connection type is compatible with your existing wellhead and downhole equipment.
Logistics should be coordinated with the supplier to confirm lead times, which can vary based on production schedules and stock availability. Incoterms such as FOB Tianjin or CIF to your nearest port should be negotiated, along with packaging details to prevent damage during transit. Payment terms, including letters of credit or advance payments, must be agreed upon in writing.
Quality checks should include dimensional verification, thread inspection and pressure testing. Request a pre-shipment inspection by an independent agency to ensure compliance with API-5CT. Documentation such as the manufacturer’s data sheet, mill test certificates and packing lists should accompany each shipment for customs clearance and project audits.
