PE-RT pipe (heat-resistant polyethylene pipe) is the abbreviation of Polyethylene of raised temperature resistance pipe. It is a non-cross-linked polyethylene pipe that can be used for hot water. Some people have highlighted its non-cross-linked characteristics. , Call it "high temperature resistant non-crosslinked polyethylene pipe". It is a kind of medium density polyethylene produced by special molecular design and synthesis process. It adopts the method of copolymerization of ethylene and octene, and obtains a unique molecular structure by controlling the number and distribution of side chains to improve the PE pipe Heat resistance. Due to the existence of short branched octene chains, the macromolecules of PE cannot be crystallized in one flaky crystal, but penetrate through several crystals to form a connection between the crystals, which retains the good flexibility of the PE tube. High thermal conductivity and inertness, while making it more pressure resistant, this modification method is similar to the common PPR pipe on the market.

Gudi In order to solve the problem that the metal parts of heating pipes are easily damaged due to oxygen permeation in the thermal cycle system, the oxygen barrier heat-resistant polyethylene (PE-RT) pipes are specially introduced. The pipeline uses the three-layer co-extrusion technology to form a uniform EVOH oxygen barrier layer on the outer layer of the PE-RT pipeline, which can effectively prevent oxygen from entering the hot water circulation system, reduce equipment corrosion, and maintain a stable energy efficiency ratio of heat radiation of the pipeline , Improve the safety of the pipeline system and extend the service life of the pipeline system.

Features

1. Good stability and long service life. The pipe has good homogeneity, stable performance and good creep resistance. Used in heating and hot water systems, it can be used for 50 years.

2. Good impact resistance and high safety. The low temperature brittleness temperature can reach -70℃, and it can be transported and constructed in a low temperature environment; the ability to resist external impact is much higher than that of other pipe materials, preventing system damage caused by rough construction.

3. Excellent flexibility-easy to bend and easy to construct. Anti-stress cracking; the pipeline is easy to bend and does not rebound after bending. Avoid damage to the pipe at the bend due to stress concentration during use. Construction in a low temperature environment, no need to preheat the pipe, easy construction.

Gudi's PE-RT oxygen barrier tube is calculated by the authority testing DIN oxygen permeability (OTR). Assuming conditions: 40℃, temperature outside 65% inside 100%, surrounding air pipe size: outer diameter 20mm, inner diameter 15mm, average EVOH thickness 188um.

Test value: 0.003g/m3, day

DIN standard value< 0.1g/m3, day

Visible up to standard

*Health: Relatively reduce the evaporation of indoor air moisture, maintain a moderate indoor humidity, prevent dryness and discomfort in the respiratory tract, and reduce the spread of bacteria. At the same time, it improves blood circulation and promotes metabolism, which is beneficial to human health.

*Comfort: The most comfortable heating method recognized in the world. The heat is evenly distributed vertically and meets the physiological characteristics of the human body. It gives people a good feeling of warming feet and cool head, warm and comfortable.

* Hygiene: The windless ground heat is evenly radiated, avoiding dust caused by convection of cold and hot air, making the indoor air clean, and reducing the infection of respiratory diseases.

*Energy saving: Floor radiant heating can be measured by households, and it can save more than 33% of energy than conventional heating. The heat is concentrated in the range of benefits for the human body.

4. Hot melt connection is easy to repair-simple installation, convenient maintenance and high cost performance. If the radiant heating piping system on the ground is damaged by external forces, the piping can be repaired by hot melt. Convenient, fast and safe, no need to replace the entire heating pipe. Project installation cost, maintenance cost is low, and cost-effective.
