Advantages of PVC pipe

In the production of general resin, the consumption of ethylene by PVC resin is the lowest and the production cost is the lowest. Domestic production of PVC per ton consumption of 0.5314 tons of ethylene, while the average per ton of polyethylene consumption of 1.042 tons of ethylene, domestic per ton of PVC resin consumption of ethylene consumption than polyethylene less than 50%. The production of PVC raw materials chlorine gas, is the balance of production of caustic soda to produce chlorine, caustic soda is an essential raw material for the national economy.  


  In addition, from the perspective of plastic products, PVC and a variety of additives compatible, in the production of pipe can be added to a large number of low filler, so that the cost of production greatly reduced. PVC pipe and metal pipe, production per cubic meter of PVC and production per cubic meter of steel and aluminum calculation, steel energy consumption is 316kj/m3, aluminum energy consumption is 619KJ/M3,PVC energy consumption is 70kj/m3, namely steel energy consumption is 4.5 times times of PVC, aluminum energy consumption is 8.8 times times of PVC. and the production of PVC pipe processing energy consumption is only the same diameter metal pipe one-third.  


  At the same time because of the smooth PVC pipe wall, no corrosion tumor, high water efficiency, used for infusion can save 20% or so. PVC pipe has a good mechanical properties, and has excellent corrosion resistance, the use of light weight, easy to install, do not need to maintain, and the use of steel for public works of the sewer pipeline, in the use of the process due to corrosion, must often coating, maintenance costs high. General construction and public works of metal pipelines about 20 years to be replaced, and the role of good processing of PVC pipe, the service life of up to 50 years.  


  Therefore, PVC pipe is a kind of production cost low, high strength, corrosion-resistant good plastic products. Generally speaking, in sewage, waste water and ventilation pipelines, PVC pipe than the use of cast iron pipe to save installation and labor costs about 16-37%, as a conductor tube than the use of metal wire casing cost savings 30-33%, while the role of chlorinated polyvinyl chloride (PVC) tube in hot and cold water, Cost savings are 23-44% than using the same size copper tube.  

Therefore, due to the advantages of PVC pipe, countries are actively developing and promoting PVC pipe.
