Standard: API2. Size: 2 3/8" --- 20"3. Steel grade: J55, C75, L80, N80, C95, P110, etc.4. Thread: NU, EU, STC, LTC and BTC5. Classification: Upset, non Upset, external upset Casing couplingA 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: API2. 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, L80-13CR4. Thread: STC, LTC, BTCPolished rod couplingPolished 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 11B2.
