ISO2531 T-type Ductile Iron Pipe Class K9

Product description Ductile iron pipe is a kind of pipe material with high strength,  corrosion resistance and wear resistance. Because of its excellent performance and reliability,  it is widely used in urban water supply, drainage, gas, heat and other fields. Ductile iron pipe manufacturing process is to cast iron pipe at high temperature after spheroidization treatment,  so that the surface of the formation of spherical graphite,  so as to improve its strength and toughness. The inner wall of nodular cast iron pipe is smooth, not easy to scale,  will not affect the water quality, and has high corrosion resistance and wear resistance, long service life. The connection mode of ductile iron pipe has two kinds: rubber sealing ring connection and flange connection. Rubber sealing ring connection is suitable for general water supply and drainage system, flange connection is suitable for high pressure, high temperature, chemical industry and other special envi…
