Grooved Couplings are commonly used components in piping systems, designed for the quick and convenient connection of pipes without the need for welding or bolted connections. They ensure a reliable pipe connection through a groove-based connection structure and a sealing ring, making them widely ap

In the manufacturing process of welded steel pipes, welding process is a crucial link. According to different welding methods, welding technology can be divided into several types. The three most common welding methods are high-frequency resistance welding (ERW), straight seam welding and spiral wel

Seamless Steel Pipe refers to a type of steel pipe that is manufactured without any welded seams or joints. It is made by heating a steel billet (or ingot), piercing it to form a hollow pipe, and then expanding, elongating, and reducing the pipe's diameter through various processes, such as extrusio
