Import Api 5ct Pup Joint 3-1/2 Eue J55 6ft — Buy in wholesale FOB from Supplier in China

This API 5CT pup joint is a 3-1/2 inch EUE threaded tubular accessory manufactured from carbon steel J55 grade per API 5CT specification, with a precise 6 ft (1.8 m) length and pin x box end configuration. The external-upset end (EUE) design provides enhanced thread engagement strength compared to non-upset alternatives, critical for maintaining tubing string integrity under tensile and pressure loads in oil and gas production environments. Henan Dongfanglong Machine Manufacture Co., Ltd produces this component for standard OCTG tubing string make-up and length compensation operations.

The J55 grade offers a minimum yield strength of 55,000 psi, positioning it as a standard H2S-serviceable carbon steel suitable for mild sour conditions where higher grades such as L80 or P110 are not economically justified. Alternative grades available from this supplier include K55, N80-1, N80-Q, L80, C90, and P110, with premium thread connections offered on request. Surface treatment options span whole phosphating or combination inside phosphating with external coating, the latter providing superior corrosion resistance for offshore or high-humidity storage environments. Thread forms cover NU, EU, NUE, EUE, TBG, and UPTBG to match legacy and current field installations.

Buyers in drilling, completion, and workover sectors use these pup joints to adjust tubing string lengths without custom pipe manufacturing, reducing non-productive time during well interventions. Standard delivery lengths range from 1 ft through 12 ft, with this 6 ft variant serving mid-range adjustment requirements. Packaging options include carton, wooden case, or wooden pallet configurations depending on shipping mode and destination customs requirements. International buyers should confirm thread inspection protocols, material test certificates, and third-party verification status directly with the supplier before finalising orders.

Henan Dongfanglong Machine Manufacture Co., Ltd operates from Puyang City in Henan Province, China, located at the intersection of 106 National Highway and Jintian Road. The supplier holds a harbor trust tier classification on the marketplace, though prospective buyers should note that response rate metrics currently show 0.00 percent with zero average response hours recorded, suggesting limited engagement history through platform channels. Direct communication via the provided address or alternative contact methods is advisable for time-sensitive procurement.

The company lists API 5CT pup joints and tubing couplings as core products, with size coverage from 1.9 inch to 4-1/2 inch tubing couplings and capability to supply premium thread products beyond standard API connections. No verified certifications, factory audit details, or stated annual production capacity appear in the available profile data. Buyers should independently verify API 5CT manufacturing licence status, quality management system certification, and request reference customers for similar OCTG supply contracts before committing to volume orders.
