The Red / Silver Steel Flange is a core component of fire fighting piping accessories, engineered to deliver secure, leak-resistant connections between pipes, valves, pumps, hydrants, and other fire protection equipment. Manufactured from high-grade steel, it is designed to withstand the pressure and temperature demands of demanding fire suppression systems.

A flange is a protruding rim or edge used to connect two sections of pipe or equipment together. Flanges are widely used in piping systems to join different pipe sections, valves, pumps, and other components. A blind flange, in particular, is a plate used for covering or closing the end of a pipe.

Flange fittings generally work by pressing two mating surfaces tightly together using threaded bolts, wedges, clamps, or other means of applying high compressive force. A gasket, packing, or O-ring is often installed between the flanges to prevent leakage. In some cases, only a special grease — or nothing at all — may be used, provided the mating surfaces are precisely formed.

In fire fighting systems, flanges are used to connect the fire hose to the fire hydrant, pump, or other equipment. They are also used to connect different sections of pipe and valves within fire sprinkler systems, ensuring reliable performance when it matters most.

Flanges are available in a variety of sizes, shapes, and materials to suit different applications. Common materials include steel, stainless steel, brass, and aluminum. The size and type of flange selected depends on the size of the piping system as well as the pressure and temperature requirements of the specific application.
