Hard PVC pipes and fittings are rapidly growing in many PVC products in China, and they are also the most consumed varieties in various plastic pipes.
China's PVC pipe has been developed and applied for more than ten years, especially the support of relevant national policies. PVC pipe production and application have made great progress. PVC pipe production has accounted for more than 50% of the total output of plastic pipe, and is widely used in industry and construction. , agriculture and many other industries.
PVC pipe is compared with metal pipe, producing PVC per cubic meter and producing steel and aluminum per cubic meter. The energy consumption of steel is 316KJ/m3, the energy consumption of aluminum is 619KJ/m3, and the energy consumption of PVC is 70KJ/m3. Steel consumes 4.5 times more energy than PVC and aluminum is 8.8 times more. The processing energy consumption of the PVC pipe is only one third of that of the same diameter metal pipe. At the same time, because the PVC pipe wall is smooth, no scale and erosion tumor, the water delivery efficiency is high, and the infusion can save about 20% of electricity.
PVC pipe has good mechanical properties and excellent corrosion resistance. It is light in weight, easy to install and requires no maintenance. Steel pipes used for public works are easily eroded during use. Coatings are often applied and maintenance is expensive. The metal pipes for general construction and public works need to be replaced in 20 years, and the PVC pipes with good processing capacity have a service life of 50 years. Therefore, PVC pipe is a good plastic product with low cost, high strength and corrosion resistance.
Generally speaking, in terms of sewage, waste water and venting pipes, PVC pipes save about 16%-37% of the installation and labor costs compared with the use of cast iron pipes; the use of metal pipes is 30%-33% less than the use of metal pipes; Water pipelines are 22%-25% more efficient than metal pipes. Therefore, because of the significant advantages of PVC pipes, all countries are actively developing and promoting. Due to the versatility of the rigid PVC pipe, significant advantages can be seen in production.
