Mpp power pipe market trend, A small editor will introduce you.

MPP power pipes have good mechanical properties and corrosion resistance. They are light in weight, easy to install, and do not need maintenance during use. However, for the sewer pipes using steel as utilities, they must be coated frequently due to their easy corrosion during use, and the maintenance cost is high. Metal pipes for general buildings and utilities need to be replaced after about 20 years, while PVC pipes with good processing performance have a service life of up to 50 years.

Due to the excellent performance of PVC-C material, especially its good rigidity and heat resistance, it can withstand the temperature of the cable core and the external pressure of soil on the pipe during the operation of the high-voltage power cable, and its price is low and installation is simple, so the market prospect of PVC power cable protection pipe should be good. PVC-C has the defect that it is difficult to process. If there is no specific formula and process, PVC-C has the defect that it is difficult to process. If there is no specific formula and process, it is difficult to produce pipes that meet the standards. At the same time, the huge market is attracting many pipe material manufacturers, and some enterprises with weak technical strength will use PVC-U pipes instead. Therefore, the casing market for PVC-C buried high-voltage power cable is the same as the PVC-U market, and the product, price and market are confused. The amount of adhesive used will affect the bonding quality of pipes. Too little adhesive will lead to incomplete bonding, resulting in water leakage. Too much adhesive will lead to slow volatilization of its solvent, and even lead to serious consequences of reduced pressure resistance of pipes.

In recent years, with the deepening of China's reform and opening up and the increasing investment of the state in infrastructure construction, the domestic demand for plastic pipes has been maintaining an annual growth rate of more than 15%. Especially in the construction of urban water supply and drainage pipe networks, PVC power cable protection pipes play an increasingly important role. The domestic production of each ton of PVC requires 0.5314 tons of ethylene, while the average consumption of ethylene per ton of polyethylene is 1.042 tons. The domestic consumption of ethylene per ton of PVC resin is about 50% less than that of polyethylene. Chlorine, the raw material for PVC production, is an important way to balance the production of caustic soda to produce chlorine, and caustic soda is an essential and very important raw material for the national economy. In addition, from the perspective of plastic products, PVC has good compatibility with various additives, and a large number of cheap fillers can be added to the production of power cable protection pipes, The production cost is greatly reduced.
