Shaanxi Weinan ductile iron pipe _ Shunxiang ductile pipe _ Shandong Ductile Iron Pipe manufacturers provided by Shunxiang ductile pipe. Shaanxi Weinan ductile iron pipe _ Shunxiang ductile pipe _ Shandong Ductile Iron Pipe manufacturers of cast iron pipe work Liaocheng Shunxiang childbirth Building Materials Co. (www.lcsxjc.com) 2014 been newly upgraded high-pressure fluid introduced more refined walks with ductile iron pipe (GB/T3092-1993), also known as ductile iron pipe factory in Shandong pipe everyday, commonly known as the clarinet. Compare welding. Walks for water, gas, atmosphere, heating oil and other daily high vapor pressure of the fluid, and other useful ductile material is characterized by smooth wall, light weight, corrosion resistance, anti-fouling function, low costs level, but also more defects, the primary are the following: aging, thermal expansion and contraction large, not long time by sunlight, poor compression function, construction defect easily cause deformation of the poor, poor deflection can easily vulgar cast iron pipe materials adding magnesium, calcium, alkaline earth metal or rare metal forging. Ductile iron pipe forging process with continuous law-making and water-cooled centrifugal forging method, a water cooling method is when modern art, power and substandard craft skills ductile cast iron pipe plain contrast, only confrontation plain cast iron pipe corrosion, and has high strength, good toughness, thin-walled, light weight, impact resistance, bending function large, easy installation, etc., but in the country has also made good use of fulfillment. In many parts of China, in ductile iron pipe, tube and pipe connecting to the small diameter of between using socket or flanged disk interface methods; ductile iron, allow restrictions corner must have superior shock resistance and sealing sex. Ductile iron pipe and tube, also known as ductile iron pipe, ductile iron pipe is made of. Their different manufacturing methods can be divided into: sand centrifuge tube socket straight, continuous cast iron pipe straight pipe and sand. By its use of different materials can be divided into: gray iron, ductile iron and high silicon iron pipe. Cast iron pipes used for water supply, drainage and gas and other pipeline projects. Ductile iron pipe fittings used in connection trench technology, also known as clamp connection technology, has become the most important technology currently liquid, gas pipe connections, although the technology development in the country late in the foreign Liaocheng ductile iron pipe prices, but Due to its technical nature of ductile iron pipe, the domestic market will soon be received. Developed since 1998 to the present, after a few years of development and application of seismic ductile iron pipe specifications, has gradually replaced the two traditional pipe connection flanges and welding. Not only technically more mature markets generally recognized, and has been actively guide the national regulations and policies.
