Development of Fire Hose Coupling
For more information about wire reinforced plastic tubing, you can check on our website, since we are one of the professional PVC hose pipe manufacturers and hose fittings manufacturers.
Fire hoses with a diameter ≥ DN100 used screw coupling in the past, which was very difficult to construct. This is due to the large diameter, shallow thread at the fireproof hose interface, weak connection, easy to leak, and deep thread, the thread at the interface The wall of the tube is too thin to withstand the working pressure of the system and it is easy to break. That is to say, the old fire protection design code requires that the pipeline behind the alarm valve, regardless of the diameter of the pipe, require the use of screw couplings to be defective, which is also the main reason why this code needs to be modified. So, what solution has this always had in the engineering practice afterwards?
Heavy-duty clamp
