Description The conversion of flanged cast iron with raw cast iron or ductile iron cast iron raw materials is produced by casting method and then adjusted by flanges and hand washers on the flanges and holes are created on the flange and it is ready for use in water supply lines. Flange cast iron converter is used to reduce or increase the fluid or pipe size. All connections of ductile iron pipes are GG25 gray cast iron and GGG40 ductile cast iron. Dactyl cast iron fittings are typically flanged to connect between cast iron pipes and valves, and polyethylene pipes, water supply system connections, and so on. Water and sewage lines are used. It should be noted that flanged cast iron fittings are generally produced in sizes from 50 to 1600 mm. The chemical composition of unbreakable cast iron is similar to that of gray cast iron, but less sulfur and phosphorus. Unbreakable cast iron has a wide range of good yield stress and acceptable ductility, and unlike hammer cast iron, it can be cast and produced with different thicknesses of thin and thick.
