Oil Coupling Nue J55 K55 L80 N80 P110 Casing Tubing Coupling

Tubing coupling is the joining of two short length pipes by the means of female and male threads. All types of tubing couplings have internal threads which are known as female thread forms. These thread forms are usually machined so that they can be coupled with the external threads on pipes known as male thread forms.

Tubing couplings are strictly designed as per API 5CT specification. There are two types of tubing couplings widely used in the pipeline coupling manufacturing industries namely:

• Non-upset Tubing Coupling
• External-upset Tubing Coupling
