41/2Ħħ LTC Coupling Oil Casing
Oil casing is primarily used for drilling oil and gas wells and the transportation of oil and gas. It includes oil drill pipes, oil casings, and sucker rods.
Introduction to Oil Casing Coupling Types:
1. LTC (Long Thread Connector): Long round coupling. The long thread connection LTC has the same thread shape as STC and can be connected; however, such connections are generally not permitted because they can withstand different torque values.
2. STC (Stub (Short) Thread Connector): Short round coupling. Both STC and LTC threads belong to the API standard threads. The only difference is the length of the threads; LTC is longer, while STC is shorter. For a 41/2Ħħ outer diameter pipe, if the actual measured thread length exceeds 3 inches, it is generally considered LTC; if it is less than 3 inches, it is considered STC.
3. BTC (Buttress Thread Coupling): Buttress thread coupling.
