I. Stable PE-X tube (cross-linked polyethylene tube) The installation of floor heating pipe must see the selection of pipe is particularly important The PE-Xa pipe is a floor heating coil that the EU must use, and the price is relatively high. The expansion connection is used during construction and the connection can be completed within a few seconds. Pipe features: 1, stable performance 2, is the largest amount of floor heating tube 3, no thermoplastic properties, can not be connected and repaired by hot melt welding Price: PE-Xa tube 25 yuan / meter or so, the import of high 20-30 yuan / m; PE-Xc pipe does not add additives, raw materials, low cost, the price is generally around 20 yuan / meter. prompt: 1. The PE-X pipe is currently the most widely used pipe in the floor heating system in Europe. In production, it is difficult for the cross-linking agent to be uniformly dispersed, the cross-linking degree is difficult to control, and the screw needs to be periodically cleaned to prevent the generation of gel particles. Therefore, the quality control of the product is difficult, and it is generally difficult for a small-scale production enterprise to do well. 2. The price difference of raw materials for heating is relatively large. Some informal manufacturers in the country randomly select raw materials so that the quality of products cannot be guaranteed. There is a certain risk when selecting low-priced products. Second, the price is high on the PB tube (polybutylene tube) The installation of floor heating pipe must see the selection of pipe is particularly important The stability of the molecular structure of the PB tube made of an environmentally friendly thermoplastic material is very good, eliminating the phenomenon of corrosion and scaling, and it is non-toxic and harmless. Fully in line with national standards for drinking water hygiene. Pipe features: 1, good thermal stability 2, excellent flexibility 3, the price is expensive. Price: generally 120 yuan / m. Imports are about 30 to 60 yuan more expensive. prompt: 1. PB tube is a kind of high molecular polymer and it is one of the most advanced chemical materials in the world. It is a kind of thermoplastic pipe, has a good temperature resistance, the maximum use temperature of up to 110 degrees, and good impact resistance. 2. The PB tube is the softest among several kinds of floor heating pipes, and the thinnest wall thickness under the same design pressure. Under the same conditions of use, the same wall thickness of the series of pipe, the safety factor is relatively high. 3, aluminum-plastic composite tube overcomes the shortcomings of traditional metal tube short life, easy rust and other shortcomings. Its easy-to-bend, non-repulsive nature makes it easy to locate during construction. It is also much less work-intensive and less efficient than pure plastic tubes in terms of construction difficulty and strength. However, the price is “high above the top†and there are not many people who use it at home.
