At present, the commonly used pipes for floor heating and radiant heating mainly include aluminum-plastic pipes, PE-X pipes, PE-RT, etc. Among them, aluminum-plastic pipes are mainly used for radiator heating, and PE-x and PE-RT can be used for floor heating. Among them, PE-X tube has high cost performance, and can be bent, easy to construct, and has good long-term pressure resistance at high temperature. It is widely used in floor heating pipes, and is currently the largest pipe used in the domestic floor heating market.
Relatively speaking, PE-RT floor heating pipe performance and cost performance are better than the other two, in order to let TXM understand the advantages and disadvantages of each tube in more detail, the following a simple comparison of these three tubes: PE-RT Floor heating pipe: The production cost is relatively low. The peroxide cross-linking process used in PE-RT floor heating pipe is the previous generation cross-linking mode of silane cross-linking process, and the intermolecular structure stability is slightly poor. Low-density polyethylene raw materials are used in the production of raw materials. Although the pipes have good flexibility, they cannot guarantee the stability of cross-linking during cross-linking and affect the service life.
PE-RT floor heating pipe is heat-resistant polyethylene. It is a non-crosslinked polyethylene that can be used in hot water pipes. It is a kind of polyethylene product produced by special molecular design and synthesis process. As a comonomer, octene precisely controls the number and distribution of branches on the polyethylene molecular chain during the polymerization process, giving the material a unique molecular structure, heat resistance, static pressure resistance and stress crack resistance of the material. Greatly strengthened. PE-RT floor heating pipe has the advantages of easy processing, weldability and good flexibility. It is mainly used in the fields of floor heating pipes, hot water supply pipes and industrial water pipes.
First, PE-RT floor heating pipe performance advantages
1, thermal stability and long-term static pressure resistance, long service life of 50
2, good impact resistance, high case
3, has good flexibility, easy to construct, easy to install
4, the pipeline heat transfer coefficient is high, which can save energy
5, excellent hygiene performance
6, the material can be recycled, with environmental benefits
7, with a high cost performance
Second, the advantages of PE-RT floor heating pipe
PE-RT floor heating pipes play an important role and value in certain industries and fields, and can be used in the normal way and method to ensure that they can fully demonstrate good contributions and effects in use. PE-RT floor heating pipe has some characteristics and performance in use, and has good advantages and characteristics in use, playing an important role and value. Here are some important advantages of PE-RT tubes:
1. PE-RT tube has good high temperature resistance. The normal working temperature of the tube is 90 ° C, the highest can reach 110 ° C, and it also has good thermal conductivity. The tube has better endurance to temperature and does not take a relatively high temperature, so there is no fear of affecting the performance of the PE-RT tube due to temperature.
2. PE-RT tube has good durability, can guarantee the service life and quality of the pipe, is durable, and is not afraid of some minor damage. If you use the pipe according to reasonable and correct use, its service life can be obtained. 50 years, but to use under normal working pressure and temperature. The length of life of any thing lies in the maintenance and maintenance of things. If it is well maintained, the service life of things will be prolonged for a long time. If you do not protect him, it may soon be damaged until it can not be use.
3. PE-RT tube has strong flexibility. The bending degree of this tube is 5 times of the diameter of common tube. It is much stronger than other tubes. It is easy to construct and coil during use and construction. Going to the coil can save laborers a lot of labor. The PE-RT tube is soft and not easy to break. It is not necessary to be afraid of damage to the quality of the tube due to excessive bending or coiling, so it can be handled and moved well during use.
4. The PE-RT tube has good connectivity and good hot-melt connection. For example, when the tube is used, it can be well connected with other tubes, and it will not leak or ventilate, and the joint can be ensured. Sealing performance. Its hot melt is good for construction, it will not let customers have a worries, so that customers are satisfied and assured.
5. PE-RT tube is corrosion resistant. PE-RT tube is resistant to strong chemical substances such as inorganic salts, inorganic acids, alkali metals and organic substances. It is made of non-crosslinked polyethylene pipe and is not afraid. Corrosion, so you can safely install and use without worrying about the environment, water quality or soil conditions around the pipe during construction.
6. PE-RT tube has good environmental protection. The tube is made of polyethylene. This material will not cause great pollution to the environment, and it can be recycled. It is completely green and has no side effects. , fully in line with national product standards.
7. PE-RT tube has high elasticity. It is also the safest when soil movement, earthquakes, etc. occur, and will not affect the orientation of the tube due to some movement of the surface. When a natural phenomenon occurs, it has high elasticity and does not change greatly with the movement of the surface, so you don't have to be afraid when special circumstances occur.
8. PE-RT tube not only has high temperature performance, but also has low temperature resistance. When the winter is cold, the use of the pipe will not be affected by the sharp drop in temperature. In this case, the PE-RT pipe has strong low temperature resistance and freeze resistance.
Third, PE-RT floor heating pipe application field
1. Low-temperature radiant heating system (including floor heating, wall radiant heating, ceiling radiant heating)
2, air conditioning pipe system
3, large parking lot, adjust the road under the snow melting system
