Properties and characteristics of PP plastic pipe
PP plastic board, full name of PP plastic pipe, is non-toxic, sanitary, high temperature resistant and recyclable. It is mainly used in the indoor cold and hot water supply system of buildings and also widely used in heating system. The double wall corrugated pipe is designed to be produced in the form of new structural wall pipe, which changes the traditional solid wall structure of PP plastic plate and reduces the weight and cost compared with the same caliber solid wall pipe. Compared with the traditional rectangular corrugations, the apparent corrugations of pipes are designed to be sinusoidal, which improves the ring stiffness of products.
PP plastic plate has a long service life. Under rated temperature and pressure, PP plastic plate can be used safely for more than 50 years;
PP plastic plate has excellent corrosion resistance and can withstand the corrosion of most chemicals. It can withstand the corrosion of high concentration acid and alkali in the pH range of 1-14 in a large range;
Because of the high rigidity of PP plastic plate, it is difficult to deform because of the glass fiber reinforced material;
PP plastic board is heat-resistant and energy-saving, with a maximum use temperature of 90 degrees. The thermal conductivity of the product is only 1 / 200 of that of steel pipe, so it has better thermal insulation performance;
The strength of the hot-melt interface is higher than that of the pipe body, and the joint will not be broken due to the soil movement or load;
PP plastic plate has good construction performance, light weight, simple welding process, convenient construction and low comprehensive engineering cost.
