Product Description
Tubing and casing couplings are critical to maintaining well integrity. They connect the various lengths of pipe, ensuring a secure and leak-proof seal. This is essential to prevent fluid migration between different geological formations, which could lead to contamination and loss of well control.
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.
Available in a wide range of sizes, weights, lengths and grades with any combination of connections.
1. Diameters - 2 3/8" to 7"
2. Weights - As Per API-5CT.
3. Lengths - Any length as per API-5CT
4. Grades - J-55, K-55, N-80, L-80, P-110 and so on
5. Connections - EUE, NUE, STC, LTC, BTC
