                    API Casing /Tubing Coupling (API-5B) Used for OCTG in Oilfield Service  4-1/2"

Product Description

    Couplings are short lengths of pipe used to connect two joints of tubing or casing, which are painted with color codes on their external surface to indicate their grades.

Tubing Coupling
Tubing Coupling can be widely used in cold and hot water supply, heating supply, fire protection, medicinal gas, industrial petroleum pipeline system etc. It has already replaced welding fittings in most Europe countries, Asia countries, America, Australia and some other countries.
1. Standard: API
2. Size: 2 3/8" --- 20"
3. Steel grade: J55, C75, L80, N80, C95, P110, etc.
4. Thread: NU, EU, STC, LTC and BTC
5. Classification: Upset, non Upset, external upset 

 
Casing coupling
A short length of pipe used to connect two joints of casing. A casing coupling has internal threads (female thread form) machined to match the external threads (male thread form) of the long joints of casing. The two joints of casing are threaded into opposite ends of the casing coupling.
1. Standard: API
2. Size: 4 1/2" --- 20"
3. Steel grade: H-40, J-55, K-55, C-75, L-80, N-80, C-95, AS-95, P-110, L80-13CR
4. Thread: STC, LTC, BTC

Polished rod coupling
Polished rod couplings are designed for connecting of the polished rod to the top rod of the string. Contrary to rod couplings, polished rod couplings have a female cone that eliminates the coupling twist-off in the course of operation.
1. Standard: API Spec 11B
