Casing pipes are an essential component in the oil and gas drilling process. They provide structural integrity to the wellbore and prevent unwanted fluids from entering the well. One critical aspect of casing pipe design is the threading, which plays a key role in joining the pipes together securely and ensuring a leak-free connection. The three most common types of casing threads are Short Threaded Coupling (STC), Long Threaded Coupling (LTC), and Buttress Threaded Coupling (BTC). Each thread type has its own distinct design features, applications, and performance characteristics. In this blog, we’ll explore these thread types, their advantages, and how they address industry-specific needs. 1. Introduction to Casing Pipe […]
