How to Connect Seamless Steel Pipes?

Groove connection of seamless steel pipe:

Groove fittings include two major categories of products: pipe fittings with a joint sealing effect include rigid joints, flexible joints, mechanical tees and grooved flanges; pipe fittings with a transition effect include elbows, tees, and four Through, reducer, blind plate, spiral welded pipe, etc.; the groove receiving part for the connection and sealing effect is mainly composed of three parts: sealing rubber ring, clamp and locking bolt.

The rubber sealing ring located in the inner layer is placed on the outside of the receiving channel and is matched with the pre-rolled groove, and then the clamp is fastened on the outside of the rubber ring, and then fastened with two bolts. Because its rubber sealing ring and clamp are designed with a sealable structure, the groove joint is sealed, and as the fluid pressure in the pipe increases, its sealing is correspondingly enhanced.

The groove connection makes the pipe connection operation simple, which is conducive to construction safety, system stability, convenient repair, labor and time saving, and thus has outstanding economic benefits. Choosing the clamp connection, although the price of a single part of the clamp is higher, the generalized benefit of the entire pipe network device is higher than that of the flange connection.

As a pipeline connection method, clamp pipe fittings can be either exposed or buried, with rigid joints and flexible joints. So it has a wide range of applications. It can be used for fire fighting water system, air conditioning cold and hot water system, water supply system, petrochemical pipeline system, thermal power and military pipeline system, sewage treatment pipeline system, etc.

Tips: ASTM A53 ERW pipe is a typical carbon steel pipe. It is largely used to convey fluids at low / medium pressures such as oil, gas, steam, water, air and also for mechanical applications.
