Groove pipe fitting connection technology, also known as clamp connection technology, has become the first technology for liquid and gas pipeline connection. Although the development time of this technology is later than that of foreign countries, it is quickly accepted by the domestic market because of its advanced technology. It has been developed since 1998, and after a few years of development and application, it has gradually replaced the two traditional pipe connection methods of flange and welding. Not only the technology is more mature, the market is also generally recognized, and has been the active guidance of national laws and regulations.

The design specification of automatic sprinkler system proposes that the connection of system pipes should be made of groove connectors or wire buckles and flanges; Pipes with diameters equal to or greater than 100mm in the system shall be connected by flanged or grooved connectors in sections.

The application of groove pipe fitting connection technology makes the complicated pipeline connection process simple, fast and convenient. This is a big step forward for pipe connection technology.

Classification of grooved pipe fittings

Trench pipe fittings include two categories of products:

(1) the connection sealing effect of the pipe fittings are rigid joints, flexible joints, mechanical tee and groove flange;

(2) Pipe fittings that play the role of connection transition are elbow, tee, tee, reducer, blind plate, etc.

The groove connection pipe fitting that plays the role of connecting and sealing is mainly composed of three parts: sealing rubber ring, clamp and locking bolt. The rubber seal ring located in the inner layer is placed on the outside of the connected pipe, and is consistent with the groove of the pre-rolled system, and then the clamp is buckled on the outside of the rubber ring, and then tightened with two bolts. Due to the unique sealing structure design of the rubber seal ring and clamp, the groove connector has good sealing property, and with the increase of the fluid pressure in the pipe, its sealing property is enhanced accordingly.

Cangzhou Shenlong Pipe specializes in the production of steel pipe and pipe fittings, including elbow, tee, reducer, etc., the product quality is guaranteed, can arrange SGS inspection, is the first choice for some large projects.
