PE-RT is a medium density (ethylene-1-octene) copolymer specially designed for hot and cold water pipes. It is a new polyethylene pipe that appears in the high temperature field. The PE-RT floor heating pipe is made of South Korea imported PE-RT (heat-resistant polyethylene) DX800, and is extruded by a professional technology and advanced production line. PE-RT was first applied in Germany in 1998 due to its excellent physical properties and processing properties. At present, PE-RT has replaced more than 80% of the PE-X market in Germany, Austria, Switzerland, Japan, the Netherlands and other countries and regions. With the development of China's CJT175-2002 standard in 2002. China's PE-RT market is also rising sharply. Graphic PE-RT tube PE-RT floor heating pipe performance comparison: (1) PE-RT floor heating pipe has good flexibility, convenient and economical laying, and can reduce the use of pipe fittings by coiling and bending during construction, thereby reducing the cost; and PE-X is resistant to brittleness and is not easy to be used. Bending, easy to break, so the probability of causing an accident increases. In order to avoid the occurrence of fractures, the mechanical connection of pipe fittings is not only troublesome, but also increases investment and increases the possibility of leakage. (2) The stress of the PE-RT pipe in the curved part of the pipe can be relaxed quickly, and there will be no “rebound†phenomenon; while the PE-X has poor toughness, it will generate a large stress in the curved part, and it is difficult to avoid due to stress concentration. Causes cracking at the bend of the pipe. (3) PE-RT pipe has low embrittlement temperature and good low temperature resistance, so it can be constructed in the case of low temperature in winter, and it does not need to be preheated when bending the pipe, which not only solves the problem that the northern region is too low in winter. Construction problems, and the bending radius can be as small as 5 times the diameter of the pipe; and PE-X is difficult to construct if it does not take preheating and heat preservation measures. (4) PE-RT floor heating pipes can be hot-melt connected to form a completely enclosed anti-seepage system, which can be laid underground. If the laid pipe is damaged due to construction, it can be repaired with pipe fittings to avoid waste of the whole pipe; PE-X pipe can only be mechanically connected with metal pipe fittings, and cannot be buried. If it is damaged, the whole pipe must be replaced. . (5) PE-RT pipe has good environmental adaptability: under the condition of working temperature of 60 and pressure of 0.4, the pipeline can be safely used for more than 50 years. DX800 and DOWLEX*2344E have passed the sanitary approval of FDA and TUV, and the pipe is in No toxic additives are added during the production process, the inner wall is smooth, no scaling, no bacteria, and can be safely applied in the field of drinking water transportation; while PE-X pipes are not suitable for water supply pipes because of their own odor. system. (6) PE-RT pipe is a green product that can be recycled and reused; PE-X pipe can not be recycled. PE-X pipe has an odor, such as opening the exhaust valve, odor gas will affect the home life. (7) PE-X pipe must reach the cross-linking degree of more than 65% and must go through the cooking process. When the degree of crosslinking does not meet this requirement, its long-term water pressure resistance and high temperature resistance are poor, and the service life cannot be guaranteed. Most of the existing PE-X production uses silane cross-linking, and its biggest disadvantage is the degree of cross-linking non-uniformity; and Weijia PE-RT guarantees the ductility and excellent pressure resistance of the tube from the meta-material. Does not require cross-linking control, reducing human factors. (8) PE-RT pipe is marked with the current meter number on the pipe body, which is convenient for calculating materials during construction and does not waste materials. (9) PE-RT has good heat dissipation performance, the thermal conductivity of PE-RT is 0.4; the thermal conductivity of PE-X is 0.35. The same specifications of the pipe, PE-RT heat dissipation performance, can save a lot of energy. Ground heat dissipation from low temperature hot water ground radiant heating systems. PE-RT floor heating pipe performance characteristics: The performance of this pipe depends on the internal structure of the pipe, and the external environment also affects the service life of the plastic pipe, such as the environment, the working pressure inside the pipe and the nature of the fluid medium in the pipe. In addition to the characteristics of the lightest weight, corrosion resistance, non-fouling and long service life, the main features of F have the main features of F: Non-toxic, no additives, hygienic. PE-X pipe is towel density polyethylene D0wLEx ※ 2344E is a copolymer resin of ethylene and sinter, with a unique molecular structure, with linear ethylene as the main chain and blush short branch as a branch. No toxic and harmful elements exist , hygienic and reliable with good toughness and outstanding water pressure resistance. Insulation and energy saving. The thermal conductivity of PE-RT is 0.4w/mk; while the number of thermal conduction systems of PE--X is 0.35whnk. The same specifications of the pipe, PE RT heat dissipation performance can save a lot of energy. Heat resistance. PE-RT tube's dimension R softening point (122)qC, the maximum working temperature up to 95 °C can meet the requirements of "Code for construction and acceptance of building water supply and drainage and heating engineering" GB50242-2002 hot water system. Service life: PE-RT pipe can be safely used for more than 50 years under the working temperature of 600C and working pressure of 0.4MPa. PE-RT pipe has good flexibility, bends arbitrarily when the bending radius is 8 times the outer diameter of the pipe, does not rebound after bending, has good low temperature resistance, and can be constructed at low temperatures in winter. The installation is convenient, the connection is reliable, the pipe buried in the ground is laid for the whole root, and there is no joint, completely eliminating the hidden trouble of leakage. Materials can be recycled and reused. · Light weight, easy to transport and install and construct; · It has good flexibility, making it convenient and economical to lay. Recyclable and meets environmental requirements; · When the pipe is bent, the stress in the bending part can be quickly relaxed, and there is no “rebound†phenomenon, which is convenient for construction operation, thereby avoiding the phenomenon that the pipe is damaged at the bend due to stress concentration during use; ·The friction loss inside the pipe is small, and the pipeline's ability to transport fluid is 10% larger than that of the same diameter PE-X pipe; ·The brittle cracking temperature is low, the pipe has excellent low temperature performance, so it can be constructed in the low temperature in winter, and there is no need to preheat when bending the pipeline. This can solve the economic situation caused by the low temperature in winter in the northern part of China. Loss, the minimum bending radius is 5 times the outer diameter of the pipe; ·Good chemical resistance, no rust and long service life. After a few years of use, the inner wall of the pipe becomes rough due to severe corrosion, and the flow resistance increases, thereby greatly reducing the water delivery capacity; ·The creep resistance is good. The creep of cross-linked polyethylene pipe changes with temperature. PE-RT does not need cross-linking plate because of the special material. After the production, the creep is permanent. · The pipeline can be safely used for more than 50 years under the conditions of working temperature of 70 ° C and pressure of 0.82 MPa; ·The pipe does not add any toxic additives in the production process, the inner wall is smooth, no scaling, no bacteria, and can be safely used in drinking water transportation and other fields; ·The impact resistance is 2 times that of PE-X pipe; ·Good heat dissipation performance, thermal conductivity of 0.4 W / (m · K), can save a lot of energy in heating applications, so PE-RT in the field of heating can play its excellent characteristics; · Weldability: After the system pipeline is damaged, it can be repaired by hot-melt welding or electric fusion welding. Precautions for installation of PE-RT pipe: PE-RT pipe is lower in hardness and steel than metal pipe. It should be protected during handling. Avoid mechanical damage caused by small external force. After dark laying, mark the pipe position to avoid damage to the pipe caused by secondary decoration. The construction environment temperature of PE-RT pipe should not be lower than 5 °C. It should be taken care of in winter construction. Special tools should be used when cutting the pipe; the cutting should be flat, the fracture surface should be vertical pipe axis, and the installed pipe can not be pressed or struck. If necessary, cover the parts that are vulnerable to external forces. During PE-RT pipe construction, prevent paint, bitumen or other chemical solvents from contacting the contaminated pipeline surface. When transporting, loading and unloading and handling, PE-RT pipe should be small, not thrown, thrown, rolled, towed, avoiding exposure to the sun, rain, should be stored at a temperature not exceeding 4 nozzles: well-ventilated and clean warehouse Internal; the distance from the heat source should be at least above Im. PE-RT floor heating pipe laying place F should not have joints. It should be laid whole, so that the pipe is body-formed and there is no leakage point. After the pipeline is installed, when the sealing pipe is covered with concrete, the pressure of the PE-RT floor heating pipe is 15 times of the working pressure of the system. The system should maintain a pressure of not less than 0.4 Mpa during the curing process. When the PE-RT floor heating pipe is laid, the fixing clamp must be set as required. Install the point: The PE-RT floor heating pipe shall be laid in strict accordance with the pipe spacing and orientation of the juice-free ceramic paper. The installation error of the floor heating pipe shall be kept at a flat, straight and pipe spacing of not less than 10 mm. Before the floor heating pipe is laid, the floor heating pipe shall be verified against the construction drawing. Whether the selection, pipe diameter and thickness meet the design requirements; confirm that there are no problems before installing. When installing PE-RT floor heating pipe, the pipe should be prohibited from twisting; when bending the pipe, the top of the arc should be restrained (topped) and fixed by pipe clamp to prevent "dead fold"; the bending radius of the floor heating pipe should not be less than 8 Double the outer diameter of the tube. When the PE-RT floor heating pipe is laid, the fixed point spacing should be, and the straight pipe section fixed point spacing should not be greater than 0. Tin. The fixed point spacing of the curved pipe section should not be greater than 0.35m. PE-RT floor heating pipe out of the ground to the sub-sector, the junction of the water collector is small: the ground floor decoration layer, the floor heating pipe out of the ground to the sub-division, the water collector Bu. The outer casing should be covered with a casing, and the manifold should be 150-200nRll higher than the decorative surface. The PE-RT floor heating pipe is connected with the sub-catchment and the water collecting device and the pipe fittings, and the ferrule type connection should be adopted; the connecting piece material is copper. The surface of the copper connector that is in direct contact with the PE-RT must be nickel plated. The loop layout of the PE-RT floor heating pipe should be as small as possible to wear the expansion joints during the construction. Cross the expansion joints, and a flexible sleeve with a length of not less than 100 ram should be provided. In the vicinity of the sub-collector, the water collector and other places where the local heating pipes are arranged densely, when the pipe spacing is less than 100 mm, the outside of the floor heating pipe should be provided with a thermal insulation measure such as a spring flexible casing. Floor heating pipe finished product protection measures: The construction of PE-RT floor heating pipe is completed. In the multi-work, multi-level cross-flow construction site, the finished product protection work is beneficial to ensure the quality and construction progress. Labor can be saved, so the following measures should be taken. In order to ensure that the floor heating pipe is not damaged during the construction process and achieve satisfactory results, the civil construction should be closely coordinated with the floor heating pipe construction, and work together to carry out the product protection work. The acceptance of the floor heating coil is not allowed to be stepped on the E line of the core tube and the polystyrene board before the concrete is filled. Ensure that the integrity of the coil is not compromised. When pouring concrete on the ground, the pedals must be laid (there should be no sharp objects such as Nails on the pedals to prevent damage to the floor heating pipes). The trolley is strictly prohibited from being crushed directly on the pipeline; when pouring concrete, it cannot be directly poured onto the pipe and must be tilted on the pedal; The shovel cannot touch the pipe when shoveling. So as not to damage the pipeline. After the ground is finished, when other sub-projects are constructed, the floor heating system equipment should be effectively protected and expanded - measures: no pollution, water collectors and pipelines. Do not dig the filling layer or wedge any objects to the filling layer; it is strictly forbidden to run heavy loads or place high temperature objects on the ground. There are many exposed pipes near the water collectors. Pay attention to protection. It is best to add a protective cover. When connecting the heating main pipe to the floor heating system, it must first be pressed and cleaned to prevent dirt and debris from clogging the loop and affect the use effect. The construction process of PE-RT floor heating pipe is not complicated. Only the construction personnel can fully understand its performance characteristics and master the construction points to avoid the occurrence of quality accidents and speed up the construction progress.
