Coupling Adaptor Joint

About Product:Ductile iron pipe is a magnesium or magnesium rare earth binding agent in molten iron ball before pouring, the graphite, the stress concentration is reduced, the pipe has high strength, high elongation, impact resistance, corrosion resistance, the advantages of good sealing; wall using cement mortar lining, improve the pipeline environment and improve the water supply capacity, reduce energy consumption; pipe using flexible interface, and the pipe itself has larger elongation, the flexible pipe is good, can soil around the pipeline and work together in the underground pipeline, improve the stress state of the pipeline, so as to improve the reliability of the pipe network.
