The pp pipe has the characteristics of corrosion resistance, high strength, water leakage resistance, small internal resistance, compressive strength, bending strength, low engineering cost, long service life, convenient installation and maintenance, etc. The maximum application temperature of PP pipe is around 95 degrees, and the heat transfer coefficient of this product is only 1/200 of that of seamless steel pipe, so it has good thermal insulation performance. The strength of the hot-melt socket of FRPP pipe is higher than that of the pipe itself, and the joint is not easy to be broken due to movement or load in the soil layer. The material of PP pipe is light, the welding method is simple, the construction is convenient, and the comprehensive project cost of the project is low.
The key of PP pipe is to use rigid high-pressure polyethylene material and add chlorosilane modified material to generate catalytic chemical bonds between polymer molecular chains to replace van der Waals force. In turn, a PP pipe with a three-dimensional grain chain porous structure is produced, which has good physical and chemical properties. Wide application temperature range; Reliable and durable material, high resistance to internal pressure; very good corrosion resistance to chemicals, high stress crack resistance in natural environment; low support force in the inner cavity, reasonably avoiding fouling; no toxicity, no mold, No germs are produced. The whole process of PP pipe application and waste is not easy to cause adverse harm to the body and the natural environment. In addition to having the advantages of light material, good strength, corrosion resistance and long service life of general plastic pipes.
PP pipe is non-toxic and hygienic; high temperature resistance and heat insulation; good ductility, cold crack resistance; relatively large thermal expansion coefficient; poor anti-ultraviolet light performance. Main uses are software for cold water and hot water systems, heating systems, air conditioning units; transportation of daily water, oil or corrosive liquids in public buildings and facilities; water supply pipes in beach equipment. PP pipes should be stacked horizontally on the leveled ground, and the bending of pipes should be reduced. The relative height of stacking should not exceed 1.5m. The warehouse or simple arch shed should not be stored outdoors, avoid sunlight, pay attention to fire safety, and the distance between pyrogens should not be less than 1m.
When transporting PP pipes and pipes, they should be handled with care to prevent oil stains, strong collisions, and sharp objects are prohibited from touching and throwing, falling, rolling, and dragging. PP pipe is continuously used and its mastery cannot be ignored. PP pipe is produced with glass fiber modified material polypropylene raw material, and the optimized glass fiber is added to PP epoxy resin to make the physical properties of the pipe better. to be stable. Because PP pipe has excellent hygiene and comprehensive structural mechanical and physical properties, it is regarded as a new generation of emerald green pipe. In the food industry, liquid food transportation pipelines; telecommunication networks and electrical equipment pipelines are new building materials that are vigorously promoted by countries all over the world at this stage.
