Determining the best connection for fire protection piping

There are four types of connection to connect fire protection pipes or fittings: groove connections, butt-weld connections, flange connections and threaded connections. You need to use fire sprinkler fittings because in the event of any change of pipe diameter in the fire protection pipework system, only connection fittings that meet the correct standard must be used. In the event of any change of pipe diameter in the fire protection pipework system, only connection fittings to the correct standard must be used.


Fire protection fittings -

The types of fire sprinkler fittings are similar to those for general piping. In terms of application, there are tees, elbows, reducer tees, crosses, caps, clamps, and live joints. In terms of materials, there are alloy, carbon and stainless steel. Connections are made in the same way as pipe connections.


Trench fittings - elbows, tees, crosses, reducers, caps

Used to connect riser control fire pipes, to support different orientations and sizes and to distribute pipes, grooved fittings are the best of the fire sprinkler fittings. By using grooved connections, project times are shorter, installation is faster and maintenance is easier.


Grooved couplings

In a ductile iron grooved coupling there are three parts, including the washer, the housing and the track head bolt and nut. They are mainly used for fire sprinkler pipes. Through the housing, a groove in the end of the riser pipe is joined. A sealing chamber with tightening bolts and nuts is formed by enclosing the gasket. This forms the sealing structure of the self-restraining pipe joint.

With the growth of industry and the economy, fire sprinkler pipes and fittings are widely used in almost all types of industries and companies and are extremely important to our daily lives. So you should always choose high-grade fire protection pipes and fittings for your project.
