Ductile iron pipe water supply main ingredients are carbon, silicon, manganese, sulfur, phosphorus and magnesium. Minimum tensile strength: 420 / Mpa ductile iron pipe k9, minimum yield strength: 300 / Mpa, the minimum elongation 7% GB / T13295-2008 ISO2531-2009 Diameter: DN80-DN2600 advantage ductile iron pipe water supply: 1, energy conservation The main material is sand, stone, local materials. 2, not aging, thermal expansion and contraction of small, long-term exposure to sunlight should be stored at room temperature for more than 40 ℃. 3, high strength, compressive strength properties of new ductile iron pipe, construction unlikely to cause deformation. The default size of the head of the company STO / Remittance / tact / in the pass / rhyme! After using the 18th ductile iron pipe is defined above by adding cast iron ball agent, after the high-speed centrifugal casting machine centrifugal ductile iron pipe into ductile iron pipes, called "ductile iron pipe", referred to as the ball pipe, ductile iron pipe and ductile iron pipe and so on. Ductile iron pipe, compared with gray cast iron pipe, high strength, good toughness, thin wall, metal with less, can withstand high pressure, the effective length of 5 m and 6 m; by the thickness of different points P, G two. Is the development direction of the cast iron pipe. Companies specializing in ductile iron pipe to the sewer specifications, ductile iron pipe, ductile iron pipe fittings LFC, tees, short tube, elbow, plugging, repair section, cast iron pipes and pipe fittings. Ductile iron pipe fittings | virtues Pipe (certified) | Ductile iron pipe is provided by virtue of Liaocheng Industry Co., Ltd. Liaocheng virtue Pipe Co., Ltd.
