What are the advantages of grooved pipe fittings for pipeline connection?

Sometimes we call grooved pipe fittings pipeline connection pipe fittings, so what is the reason for giving it such a unique or industry name?

Sometimes we call grooved pipe fittings pipeline connection pipe fittings, so what is the reason for giving it such a unique or industry name? In fact, there are certain reasons in it, which has fully demonstrated the importance of grooved pipe fittings in pipeline connection.
In the pipeline connection of our modern construction, we have basically used grooved pipe fittings. The main reason is that when using grooved pipe fittings, only a groove is squeezed out of the outer surface of the connected pipe with a groove rolling machine without destroying the inner wall structure of the pipe. This is a unique technical advantage of grooved pipe fittings connection.

Compared with the traditional welding connection method, the first is simple operation, the second is smooth and beautiful appearance, the third is already well 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.
