The crown plastic PVC pipe PVC pipe drainage pipe products are sanitary grade polyvinyl chloride (PVC) resin as the main raw material pvc pipe image, adding an appropriate amount of stabilizers, lubricants, fillers, coloring agents squeeze through plastic extruder the injection molding and injection molding machine pvc pipes, cooling, curing, stereotypes, testing, packaging and other processes to complete the pipe, tube production. 1, the pipe surface hardness and excellent tensile strength, high safety factor pipeline. 2, good aging resistance, normal life of up to 50 years. 3, conduit for inorganic acids, alkalis, salts excellent corrosion resistance for industrial sewage and transportation. 4, the pipe friction coefficient is small, the water smooth, clogging, less maintenance work. 5, material oxygen index, with self-extinguishing. 6, the pipe line expansion coefficient, is 0.07mm / m, little affected by temperature deformation. Small thermal conductivity and elastic modulus, excellent as compared with cast iron pipes anti-freeze properties. 7, pipe, tube connections can be bonded, the construction method is simple, easy to operate, install high efficiency. As one of the products of technological development pvc pipes, PVC pipes in everyday life can and striking. In Europe pvc pipe, 1980 - 1990 growth rate was 8% plastic tube, 2001 annual production of 3.5 million tons, of which 60 per cent of PVC pipe. 1985 US plastic pipe production was 1.6 million tons in 1999 annual output of about 3.6 million tons, of which, PVC pipe accounted for 78%. And China's first root UPVV flared pipe is in 1983 born in Shenyang plastics factory, after the Chinese mainland with a PVC, drainage capacity. The late 1990s is the period of rapid development in China PVC pipe. During some of the more than 50,000 tons annual capacity of the plant gradually put into operation, tons more than the scale of production of more than 30 PVC pipe factory. Annual production capacity of 2 million tons of plastic pipe. pvc pipe, pvc pipe, pvc pipe provided by the Dongguan City, the crown plastic products Limited. Dongguan City, the crown Plastic Products Co., Ltd. (www.gddgyg.com) strong, credible, in Dongguan, Guangdong wire, pipe, plate manufacturing equipment industry has accumulated a large number of loyal customers.
