Product Description of Tubing Couplings

We offer a comprehensive size range of tubing couplings, including 2-3/8", 2-7/8″, 3-1/2″,4″ and 4-1/2″ in J55, K55, N80, P110 grades. All our couplings are designed to meet the API Specifications 5CT/5B standards.

Couplings serve as short lengths of pipe used to connect two joints of tubing or casing. They feature painted color codes on their external surface to indicate their respective grades.

API EUE Tubing Couplings:

Our EUE petroleum tubing couplings are designed in accordance with API 5CT/5B standards and manufactured using high-quality seamless steel. With an outer diameter ranging from 77.80mm to 141.30mm, they provide a larger outer diameter compared to non-upset threaded end products. The API external-upset-end (EUE) tubing connection is widely utilized due to its reliable performance in most well conditions. The EUE joint exhibits superior tensile strength and pressure resistance compared to the pipe body itself, making it a highly efficient connection option.

API NUE Tubing Couplings:

Designed according to API 5CT/5B specifications, our NUE tubing couplings are made from top-grade seamless steel materials. These couplings come with an outer diameter range from73.02mmto132.08mm.API non-upset (NUE) tubing is less commonly used than EUE tubing due mainly to its slightly lower cost and reduced joint strength comparedtoEUEcoupling.Thesmaller coupling joint diameter of NUE provides advantages when clearance is limited.

Product Details:
1.Size: Available in sizes -2-3/8”,2-7/8",3-1/2”,4",and4-1 /2"

Standard: Compliant with API Specifications -API 5CT/5B

Type: EUE, NUE

Grade: J55/K55/N80/L80/P110

Packaging: Securely packaged on wooden pallets and tightly wrapped/W paper carton

Our manufacturing process involves the careful selection of raw materials, mechanical testing including tensile strength evaluation, impact testing, chemical properties control, sulfide stress cracking tests (for material grades C90 or T95), size tolerances control for OD, wall thickness,length,and straightness. We also ensure precise thread control in terms of threads quantity per inch and thread angle. Premium threads undergo even more rigorous quality checks.

Additional steps in our production include heat treatment to enhance the coupling's mechanical properties,
application of additional markings as required by specifications, material certification verification,
and product specification level (PSL-2 or PSL-3) compliance.
