Heat-resistant polyethylene pipe, the English abbreviation of rr, is a non-cross-linked polyethylene pipe that can be used for hot water. Some people highlight its non-cross-linked characteristics and call it "high-temperature-resistant non-cross-linked polyethylene pipe". vinyl pipe”. It is a medium-density polyethylene produced using a special molecular design and synthesis process. It uses the copolymerization method of ethylene and octene to obtain a unique molecular structure by controlling the number and distribution of side chains to improve the durability of the pipe. Thermal properties, the heat-resistant temperature of the tube is °. Due to the presence of short octene branches, the macromolecule cannot be crystallized in a sheet crystal, but runs through several crystals, forming a connection between the crystals. It retains the good flexibility and high thermal conductivity of the tube. properties and inertness, while making it have better pressure resistance and can be used to transport hot water below ℃ for a long time. It retains good flexibility and inertness, and is resistant to low temperatures (-℃), good impact resistance, and better pressure resistance. It is non-toxic, odorless, pollution-free, green, environmentally friendly, and recyclable. The tubes can be connected by hot melt, making installation and maintenance easy. Characteristics of R pipes: light weight, easy to transport, install and construct. .It has good flexibility, making it convenient and economical to lay. The pipes produced can reduce the use of pipe fittings and reduce construction costs through coiling and bending methods during construction. 3. When the pipe is bent, the stress in the bent part can be relaxed quickly without "rebound" phenomenon, which facilitates construction operations. .The friction loss in the pipe is small, and the fluid transport capacity of this type of pipe is greater than that of metal pipes of the same diameter3. .Low brittle temperature. The pipe has excellent low temperature resistance, so it can be constructed even at low temperatures in winter, and the pipe does not need to be preheated when bending. .Good chemical corrosion resistance, no rust, long service life. .Good environmental adaptability. .It can be used safely for more than 10 years under the conditions of operating temperature of 0.0 degrees Celsius and pressure of . .No toxic additives are added to the pipe during the production process. The inner wall is smooth, does not scale, and does not breed bacteria. It can be safely used in drinking water transportation and other fields. .The impact resistance is twice that of pipes. .Good heat and pressure resistance. .Can be hot-melt connected and mechanically connected, reliable and leak-free. And - can only be connected mechanically. 3. Green and environmentally friendly products, recyclable and reusable. .Good resistance to high temperatures and can be used for years under appropriate pressure conditions. Good resistance to low temperature frost and excellent impact resistance, suitable for winter construction. Good resistance to chemical corrosion and long service life. Non-toxic and odorless , good hygienic performance. Light weight, good flexibility, and can be supplied in coils. The hot-melt material is recyclable and has environmental benefits.
