Ductile Iron Jacking Pipe:
Ductile Iron Jacking pipe is to make a tubular reinforced concrete protective jacket on the external wall of T-type joint pipe. There’s a jacking flange welded on the spigot of the pipe. During the pipe jacking, the pushing force is evenly passed from the flange with ribbed plate welded at the spigot to the socket, thus ensuring the pushing operation will not cause deformation of the spigot and will not damage the outer protective sleeve.
Jacking pipes are applied when the pipeline is needed to cross obstructions such as roads, railways, rivers and buildings, while trench excavation is not allowed or difficult to prepare on the construction site. Jacking pipe adopts T-type flexible joint. It features sound sealing performance, faster installation, more reliable internal and external anti-corrosion coating, and is adaptive to various soil environments and different transmitted media.
