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.

Characteristics of grooved pipe fittings

1. Fast installation speed. The groove-type pipe fitting only needs to install the standard parts supplied, and does not need welding and galvanizing, so the installation speed is significantly faster than the screw connection and flange connection, and the pipe pipe automatic centering centering can be realized through the clamp, the construction efficiency can be greatly improved, and the pipe installation period can be effectively shortened.

2, safe and reliable. On the one hand, the groove machine and hole opener used in the installation process are supporting special tools provided by the manufacturer, which can ensure the machining accuracy of the pipe end groove; On the other hand, the sealing ring in the clamp chamber plays the role of grasping the pipe, realizing self-tight sealing, the greater the internal pressure, the better the sealing. The nominal pressure of pipe fittings can be as high as 2.5mpa.

3, easy to install. Groove type pipe fittings need to tighten the bolt number is small, convenient operation, disassembly and assembly only need a wrench, workers do not need special skills, can be on duty after training.

4. The economy. The trench clamp connection will not destroy the galvanized layer, and the pipeline does not need to be installed twice, galvanized and transported, so the installation cost is significantly reduced. The installation speed is fast, which can shorten the construction period, make the project put into use in advance, and create economic benefits in advance.

5. Environmental protection. The piping and installation of trench pipe fittings do not need welding, do not need open flame operation, so there is no welding slag pollution, do not destroy the galvanized layer inside and outside the pipe, it will not pollute the site and the surrounding environment, and is conducive to fire prevention. The groove connection reduces the transmission of noise and vibration due to the gap between the pipe ends.

6, not limited by the installation site, easy maintenance. The grooved pipe fitting can be pre-assembled, and the bolts can be adjusted arbitrarily before locking. The pipe fitting sequence has no direction, and it can be operated in a relatively narrow working space and place. Only 2 joints need to be removed during maintenance to clean and replace the pipe.
