Ductile Iron Pipe(Tube), also namely Ductile Cast Iron Pipe or Ductile Iron Spun Pipe is a centrifugally cast product. A controlled amount of molten iron is introduced into the rotating mold, which generates a centrifugal force that holds the iron in place against the mold until it solidifies. The pipe is then removed and furnaceannealed to obtain the prescribed physical properties and the most common type is T type Ductile Iron Pipe.
T type Ductile Iron Pipe, known as Push On Joint or Socket Spigot Joint or Tyton Joint is most used joint for Ductile Iron Pipe. It is a flexible joint that allow the angular deflection and longitudinal movement to adapt to certain foundation settlement without any loss in performance, and the self-sealing is achieved by gasket rubber ring between the socket and spigot, meanwhile it features easy installation and sound sealing performance, and it is widely used in the fluid supply system.
