In the construction market, the use of PVC pipe, there are two: one is the pressure tube, one is non-pressure pipe. Cast iron pipe and copper pipe is generally used in the past as a pressure building materials, not only serious corrosion and require regular maintenance and replacement cost is higher. Building on the now widespread use of foreign pressure water pipe, hot water supply pipe mostly use PVC pipe. Small-diameter PVC pipe (UPVC pipe, CPVC pipe) with low cost, corrosion resistance, without regular maintenance and replacement of other advantages. The large diameter PVC pressure pipe (diameter 100-900mm) substitution of cast iron pipes, enhancing small mud tubes, water systems, good fluidity, corrosion resistance, low weight. Electricity, good water quality. And with PVC foam core under no pressure pipe as indoor plumbing pipes and stormwater systems, noise problems can be solved under indoor plumbing. Public works outfall no-pressure PVC pipe, corrosion resistant, corrosion from hydrogen sulfide, long life, light weight, low installation cost, easy connection and sealed, prone to breaking. In addition, another market with a string of pipe line construction and underground cable protection pipe is PVC pipe, currently used varieties of DS tube, double wall pipe and single wall corrugated pipe. Tubing is also a vast agricultural areas PVC applications. China is a resource-scarce countries, at present, the majority of farmland soil drainage also are used for irrigation, water waste is very serious. And due to lack of water, a lot of not very good farmland irrigation, low crop yields. And with a PVC pipe for irrigation, can be saving about 50%. The use of PVC fixed or semi-fixed irrigation systems of farming, not only saves water, but also to increase production, equipment, corrosion, etc., significant savings in the cost of spray irrigation facilities. At present, China is still not a completely solid pipe irrigation County, most of the country is also a lack of basic understanding of irrigation pipe, therefore, increase in rural PVC pipe irrigation publicity and promotion efforts, and its potential is huge. Characteristics of a PVC pipe, light weight, convenient transportation and handling; PVC pipe material is very light and convenient loading and unloading of construction, saving labor 2, excellent chemical resistance; PVC pipe has excellent resistance to acid, alkali, corrosion resistance, for Uses for the chemical industries. 3, fluid resistance; the smooth wall PVC pipe for fluid resistance small, the drag coefficient of only 0.009, lower than other pipes in the same flow, the diameter can be reduced. 4, mechanical strength; PVC pipe the water pressure resistance strength, resistance to external pressure strength, impact strength etc very good for a variety of conditions of piping works. 5, good electrical insulation; PVC pipe full of excellent electrical insulation, used in wires, cables of catheter, and wire construction on the pipe. 6, does not affect water quality; PVC pipe by dissolution does not affect the water quality tests confirmed, for the present the best pipe water pipe. 7, simple construction; quickly and easily bonded construction of PVC pipe, so the low cost of construction projects. China is currently used some PVC pipe: UPVC pipe: UPVC pipe is the largest construction applications. Currently in the various provinces of the water pipe system and promote the use of residential water pipes, drainage pipes mainly used in the construction industry, rainwater pipes and conduit. UPV tube has chemical resistant, self-extinguishing and flame resistance, first resistance is good, smooth wall, good electrical properties, but low UPVC pipe toughness, linear expansion coefficient, a narrow temperature range. UPVC pipe development benefits are obvious, the production and use of UPVC saving 55-68% than the cast iron pipe, UPVC water supply pipe production and use of energy-saving 62-75% than galvanized pipe, and the price is the same size unit length of galvanized pipe is only 1 / 2, the installation cost 70% lower than the galvanized pipe, use 1 ton UPVC water pipes can be replaced 12 tons of cast iron pipes, use one ton UPVC bellows can save 25 tons of steel. UPVC pipe with pvc resin as the main raw material, adding the necessary light, heat stabilizers, anti-aging agent, impact agents and other additives, extrusion molding. Mainly used for building drainage, agricultural irrigation, sewage and other chemical systems. Special formula can guarantee 50 years without deterioration UPVC pipes and use of a performance, light weight, only about metal pipe 1 / 6-1 / 7, easy to transport 2, the use of non-screw connection, easy installation, low installation costs 3, sound insulation, good thermal insulation properties, thermal conductivity metal plastic only 1/100 4, good chemical resistance, never rust 5, wall smooth, water resistance, flow can be increased by 30% without scaling, no bacteria, hang dry tone 6, long service life, generally up to 20 years -50 years. 7, looks beautiful foam core pipe: foam core pipe is a three-layer co-extrusion technology, the outer and inner layers of the same general UPVC pipe, an intermediate is a relatively low density of 0.7-0.9 foam layer of the new pipe, which is eight times the rigid ring to ordinary UPVC pipes, foot stability and changes in temperature, good heat insulation, especially foam core blocking noise propagation to have to pay more for high-rise building drainage systems. Foam core pipe than the solid wall pipe can save more than 25% of raw materials, and the inner wall of the compression capability has been greatly improved. Foam core pipe and silencer in the wall with a number of male helix, the water along the inner wall of continuous spiral flow freely, forming a column in the center of the drain, so that the pipe pressure is reduced by 10%, general capacity increased by 10 times, displacement increased six-fold lower than the average noise UPVC drainage 30-40db. Radial reinforced PVC pipe: the production of such pipes using special molds and molding subsequent device is a heavy large diameter ultra-gluten grain glass ring pipe. Characterized by the outer wall of the tube with radial ribs, can greatly enhance the role of the pipe ring stiffness and compressive strength, especially for municipal drainage works. Double-wall corrugated pipe: double wall corrugated pipe is extruded simultaneously two concentric tubes, bellows and then welded to the inner wall of the outer tube is smooth and made of brass. Has a smooth inner and corrugated outer wall, light and high-strength, than ordinary UPVC pipes can save 40-60% of raw materials, mainly used for communication cable protection pipe, the exhaust pipe construction and agricultural drainage pipes. Features: Product structure unique compression capability, smooth wall, over flow, with good bending performance, can be adapted to the soil uneven ups and downs, long life, buried can be used for more than 50 years. PVC reinforced through the tube: The inner and outer layers made of plastic extrusion, sandwiching a synthetic, flexible, bendable. Transparent PVC pipe has good acid and alkali, oil, anti-aging properties, can replace the rubber tube, and inexpensive. Are widely used to transport nitrogen, oxygen, carbon monoxide and other gases and water, dilute alkali, oils and other liquids, may also be used water heater, sprayer, stove and other conduits. CPVC pipe: CPVC pipe is up by more than 66% of the chlorine content of chlorinated PVC processing derived from a heat-resistant plastic pipe. CPVC pipe of a heat resistant temperature higher than UPVC pipe above 30 ℃, but also improve the dimensional stability, the linear expansion coefficient is reduced. CPVC pipe heat aging resistance, excellent chemical resistance, not deformed in boiling water, can be used for hot water, corrosion-resistant transport of liquids and gases.
