API 5CT 2 3/8" to 4 1/2" J55 L80 N80   OCTG Tubing Coupling

 

Product Description

 

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
   

  The table below shows the specifications with respect to these two tubing couplings.
