The BTC/LTC/STC coupling is an integral part of the  API 5CT L80 seamless carbon steel Oil casing Pipe. It is used to connect two sections of Pipe together, providing a secure and leak-proof connection. The BTC (Buttress Thread and Coupling) coupling is the most commonly used type, as it offers excellent sealing properties and is easy to install. The LTC (Long Thread and Coupling) coupling is used in applications where a higher level of sealing is required, while the STC (Short Thread and Coupling) coupling is used in shallow wells or low-pressure applications. The importance of the  API 5CT L80 seamless carbon steel Oil casing Pipe with BTC/LTC/STC coupling in the Oil industry cannot be overstated. These Pipes and couplings play a crucial role in ensuring the integrity of the wellbore and preventing any leaks or failures that could lead to environmental damage, loss of production, or even accidents.
