PE-RT floor heating pipe:
The mechanical properties of the copolymer are very stable. Because of its unique structure of ethylene main chain and octene short branch chain, it has excellent toughness, stress cracking resistance, low temperature impact resistance, excellent long-term water pressure resistance and heat creep resistance of octene.
PE-RT raw materials not only have qualified creep rupture curve, but also have moderate pipe price, convenient and fast construction compared with other varieties. The connection form belongs to the reliable standard mutual melting hot-melt connection form at present. The diameter of pipe fittings is larger than the inner diameter of pipes of the same specification. Because there is no mechanical connection mode of local shrinkage in the system, the fluid resistance of the system is relatively low Small.
With the development of plastic technology, indoor heating system can provide a variety of plastic pipes for different purposes. The plastic pipe has the advantages of smooth inner wall, small flow resistance of heat medium, acid and alkali resistance, long service life and convenient installation. In recent years, PE-RT has been widely used in the floor heating system. As a new generation of heating pipe, PE-RT is gradually becoming a product in the floor heating market.
characteristic:
1. Softness: PE-RT pipe is relatively soft and has good flexibility, which makes it convenient and economical to lay. During the construction, the use of pipe fittings can be reduced by coiling and bending. Special tools are not needed during the construction, so the processing cost is relatively low.
2. Thermal conductivity: pipes used for floor heating need to have good thermal conductivity. The thermal conductivity of PE-RT is twice that of PP-R and pp-b. Very suitable for floor heating.
3. Low temperature heat resistance and impact resistance: PE-RT pipe has superior low temperature resistance, and it is not easy to be broken due to impact during winter construction, which increases the flexibility of construction arrangement, so it can be constructed under low temperature in winter, and the pipe does not need to be preheated during bending. It can be safely used for more than 50 years under the working temperature of 70 ºC and pressure of 0.4MPa.
4. Environmental protection: PE-RT pipe in the production process does not add any toxic additives, can be recycled, does not pollute the environment and good chemical corrosion resistance, long service life. The inner wall is smooth, no scaling, no bacteria, and can be safely used in the field of drinking water transportation.
5. Processability stability: PE-RT processing is simple, pipe properties are basically determined by raw materials, performance is relatively stable.
