AS Heat-treatment Centrifugally Cast Tubes are utilized in various high temperature applications. Typically the service temperature ranges between 400 to 1300 degrees centigrade.AS Heat-treatment Centrifugally Cast Tubes are used as stressed components in many of these demanding environments.
Overview of the Centrifugal casting process
1. Heat-treatment Centrifugally Cast Tubes are the casting process specifically adapted to the production of cylindrical parts.
2.The pipes are made by pouring molten metal into a rotating mould. The metal is solidified in cylindrical shape with high centrifugal force.
3.The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical situation with pipes. The inside diameter has more impurities and inclusions, which can be machined away.
4.The process can also be adopted to produce various other products, using molds that can be permanent or expendable. The rotational speeds are lower than those used in centrifugal casting. This process is used for making wheels, nozzles, valve bodies etc.
5.Diameter: 50mm - 500mm; Length: less than 400mm.
