Ductile Iron Flange Adapter
The ductile iron flange adapter is a joint made of ductile iron with flange end connected to the flange of valves, water meters ,pipe fittings etc and the socket end connected to the spigot end of pipes such as PVC pipes, ductile iron pipes, steel pipes, and GRP pipes etc. It is commonly used to connect pipes to flanges ends of our pipeline parts.
The commonly used ductile iron material is EN GJS400-18, EN GJS450-10, ENGJS500-7 or ASTM 65-45-12. Working pressure can be PN10/PN16 or PN25.ductile iron flange adapter can’t afford higher pressure than PN25.
