Cast Iron and Steel Pipe Fittings
Cast iron fittings basically include threaded pipe connectors used to connect threaded pipes in industrial pipe systems for cold and hot water, non-aggressive fluids, gas, steam, fire fighting and other applications. They are made of white malleable cast iron and compliant with EN 10242 and ISO 49. Working pressure 25 bar (up to 120°C), 20 bar (300°C). Normally zinc-plated, but also available black, not plated.
The connectors are threaded with BSP female parallel thread (Rp, ISO 7-1), BSPT male taper thread (R, ISO 7-1), pipe unions (nuts and couplers) with BSP parallel thread (G, ISO 228-1).
