Flanges

Manufacturer, Stockists and Dealers of Flanges

Flanges are a reliable way to connect pumps, pipes, valves, and other equipment in order to make a pipework system. Flanges add flexibility by allowing an easier disassembly and improved access to system components. A flange connection comprises pipe flanges, gaskets, and bolting.
