What is Manufacturing Process Of Ductile Iron Pipe Fittings?
The ductile iron pipe fittings are manufactured with 90% recycled iron. The lost foam material is utilized to manufacture Di fittings using an advanced technique. In this method, a replica is made using thermocol that acts as a casting design pattern. Here, hot metal is poured into these replicas’ cavities. After the metal is cooled metal is taken out and cleaned. The material is subjected to different testing methods to check its quality. The fitting can be coated with different specifications as per requirements.

How are Ductile Iron Water Pipe Fittings Made?
Ductile iron is primarily designed from crude oil that is produced as ore is smelted in the blast furnace. The Ductile Iron Water Pipe Fittings contain 90% of pig iron with a high carbon content. Its superior chemical properties make it stable in different systems. The pig metal is then melted using a blast furnace, and carbon is forced beyond its normal capacity. The Di Water Pipe Fittings have excess silicon, sulfur, and manganese that form the spherical graphite modules when the metal cools. This process helps create reliable and wear resistant Ductile Iron Hub Fitting. Your system performance and casting quality are improved if the material is formed with this process.
