Groove fittings are sometimes referred to as pipe link fittings. So what is the reason for giving it such a unique or industry name? In fact, there are certain reasons in it, which in fact has fully explained the importance of grooved pipe fittings in pipeline connections. In our modern construction of pipeline connections, we have basically used grooved pipe fittings. The main reason is that when grooved pipe fittings are used, only a groove is squeezed out by a roll groove machine on the outer surface of the connected pipe without damaging the inner wall structure of the pipe. This is the unique technical advantage of grooved pipe fittings. Compared with the traditional welding connection method, the first is simple operation, the second is smooth and beautiful, the third is anti-corrosion treatment, and the fourth is not restricted by the technical operation of workers. These reasons and reasons are enough to prove the importance and status of grooved pipe fittings in pipeline connection.
