Import Api 5ct Casing Coupling Tubing Coupling — Buy in wholesale FOB from Supplier in China

This listing covers API 5CT casing and tubing couplings from Hebei Borun Steel Trade Co., Ltd, manufactured to API 5CT and 5B standards. The product range includes tubing couplings for sizes 2-3/8 to 4-1/2 inches and casing couplings for sizes 4-1/2 to 20 inches. Steel grades span H40, J55, K55, N80, R95, L80, C90, T95, P110, and Q125, with end finishes available in NUE and EUE for tubing couplings, and STC, LTC, and BTC for casing couplings. Colour coding differentiates grades: Bright Green for J55/K55, White for P110, and Red for N80/L80.

The couplings are produced from seamless or welded steel, with material properties conforming to API 5CT specifications for yield strength, tensile strength, and hardness. Tubing couplings are typically used to connect sections of tubing in oil and gas wells, while casing couplings join casing pipes to form a continuous string. Both types undergo non-destructive testing, including hydrostatic and pressure integrity checks, to ensure compliance with industry standards. Surface treatments such as phosphate coating or zinc plating are standard to enhance corrosion resistance.

These couplings are essential for well construction in the oil and gas industry, providing structural integrity and leak-proof connections in downhole environments. Buyers typically include drilling contractors, oilfield service companies, and energy producers sourcing for onshore and offshore projects. Packaging options include wooden cases or pallets, with custom configurations available on request. Lead times and MOQs are confirmed directly with the supplier, as these depend on the specific grade, size, and order volume.
