Grooved type flexible metal hose for fire protection

Features of special grooved flexible metal hose for fire fighting:

1. Fast: No need for welding and secondary galvanizing, no need to install fastening bolts, pipeline installation speed is more than three times faster than traditional welding, threaded connection and flange connection.

2. Convenience: lighter than the flange, only two fastening bolts are needed, no lock holes are required, and there are no special requirements for installation.

3. Reliable: stainless steel corrugated plate made of 304 material, long service life. Press the clamps, gaskets and grooves at the end of the tube tightly on the entire circumference, the tensile strength of the tube is high, the test pressure is 4.2Mpa, the temperature is -30°C-100°, and the vacuum degree is 0.08Mpa.

4. No pollution: The groove compensator is installed, there is no welding slag problem, which can ensure the smooth flow of the pipeline. Connected pipes, especially fire sprinkler systems, are free from rusting and clogging of equipment, sprinklers, etc. in the pipes due to other connections.

5. Economical: Compared with flange connection, it saves about 20% of the total project cost.

Grooved metal braided hose is a new type of pipe metal hose in recent years. Improvements have been made to the original, eliminating flange connections at both ends and changing groove connections. It has the advantages of convenient installation, cost saving and better use effect. Braided flexible connectors for plumbing equipment are an important part of a variety of systems that require fluid transfer flexibility, and they are constructed from lengths of flexible metal hose assemblies.
