PE-RT floor heating pipes are non-toxic, odorless and non-polluting. The sanitary indicators of green environmental protection pipes are in line with national standards. Acid, alkali, creep resistance, anti-aging, excellent long-term hydrostatic and impact resistance. The inner and outer walls are smooth and the fluid resistance is small; the installation is simple and reliable, and the advanced heat fusion method is adopted, and there is no leakage. Low-temperature hot water floor radiant heating system, laying the heating pipe in the ground filling layer, according to the requirements of durability, use condition level, heat medium temperature and working pressure, system water quality requirements, material supply, construction technical conditions and investment costs, etc. The comprehensive evaluation selection is determined.
PE-RT is a heat resistant polyethylene, a high molecular copolymer of ethylene and octene. PERT floor heating pipe is light in weight, easy to transport, install and construct, has good flexibility, and is convenient and economical when laying. When the pipeline is under construction, the pipe can be used to reduce the use of pipe fittings and reduce the construction cost. The radius can be as small as 5 times the outer diameter of the pipe. The stress in the curved part can be quickly relaxed, there is no "rebound" phenomenon, and the construction operation is facilitated, thereby avoiding the pipe being bent due to stress concentration during use. Destruction occurs, the friction loss inside the pipe is small, the brittle fracture temperature is low, and the pipe has excellent low temperature resistance. Therefore, it can be warmed in the case of winter, and does not need to be preheated when bending the pipe. The chemical corrosion resistance is good, Rusting, long service life, under the condition of working temperature of 70 degrees and pressure of 0.6Mpa, the floor heating pipe can be safely used for more than 50 years.
First, PE-RT floor heating pipe advantages:
1. High temperature resistance (up to 110 ° C)
2. Impact strength
3. Good flexibility at low temperatures (up to -40 ° C)
4. Strong resistance to brittle cracking at low temperatures
5. Good creep resistance
6. Safety and health
Second, PE-RT floor heating pipe features:
1. Light weight, easy to transport, install and construct;
2. The floor heating pipe has good flexibility, which makes it convenient and economical to lay. The pipe produced can reduce the amount of pipe fittings and reduce the construction cost by coiling and bending.
3. When the pipe is bent, the stress in the curved part can be quickly relaxed, and there will be no “rebound†phenomenon, which is convenient for construction operation, thereby avoiding the phenomenon that the bending of the pipe is damaged due to stress concentration during use. ;
4. The friction loss in the tube is small, and the fluid transporting capacity of the tube is 30% larger than that of the same diameter metal tube;
5. The brittle fracture temperature is low and has good environmental adaptability. The pipe has excellent low-temperature resistance, so it can be applied in the case of low temperature in winter, and the pipe does not need to be preheated when bent. This can solve the economic loss caused by the low temperature in winter in the northern part of China, and the bending radius can be as small as 5 times the outer diameter of the pipe; while the bending radius of PE-X is as small as 8 times the outer diameter of the pipe.
6. PE-RT floor heating pipe has good chemical corrosion resistance, no rust and long service life. After a few years of use, the inner wall of the pipe is severely corroded, the inner wall is rough, the friction coefficient is increased, and the water delivery capacity of the pipe is reduced;
7. PE-RT floor heating pipe has good heat and pressure resistance performance. Under the condition of working temperature of 70 °C and pressure of 0.4 MPa, the floor heating pipe can be safely used for more than 50 years;
8. The pipe does not add any toxic additives during the production process. The inner wall is smooth, does not scale, is not easy to breed bacteria, and can be safely used in drinking water transportation and other fields;
9. The impact resistance of PE-RT floor heating pipe is 5 times that of PVC-U pipe;
10, good heat dissipation performance, thermal conductivity of 0.4w / m • K and PE-X, higher than PP-R 0.22w / m • K and PB 0.17w / m • K, can save energy in floor heating.
11. PE-RT floor heating pipe can be thermally welded and mechanically connected, which is reliable and does not leak. The PE-X can only be mechanically connected.
12, PE-RT floor heating pipe green environmental protection products, can be recycled and reused, but PE-X can not, PE-RT pipe is used in low-temperature hot water floor radiant heating, generally S5Φ20 × 2.0mm is more reasonable.
