As we all know, F2159 PEX Crimp Fitting refers to a kind of pipe used as a carrier of low-temperature hot water circulation in low-temperature hot water floor radiant heating system (referred to as floor heating). So what is a floor heating pipe is to involve floor heating pipes of various materials. Next, the floor heating construction team will show you what is the difference in the performance of various materials of floor heating pipes?

　　The floor heating construction team stated that domestic production generally uses medium-density polyethylene or high-density polyethylene and silane cross-linking or peroxide cross-linking methods. It is the chemical bond connection between the linear long molecular chains of polyethylene to form a three-dimensional network molecular chain structure. Compared with general polyethylene, it has improved tensile strength, heat resistance, aging resistance, stress crack resistance and dimensional stability. The entire production process is a chemical reaction process. This kind of floor heating has difficulties such as the crosslinking agent is not easy to disperse uniformly, the degree of crosslinking is difficult to control and consistent, and the screw needs to be cleaned regularly to prevent the generation of gel particles. The quality control of the product is difficult, and it is difficult for ordinary small manufacturers to do well. Qualified PE-X pipe has the advantages of good mechanical properties, high temperature resistance and low temperature performance. However, PE-X pipes have no thermoplastic properties and cannot be connected and repaired by hot-melt welding.

　　 is known as the soft gold in plastics. It has superior creep resistance and mechanical properties. Among several floor heating pipes, it is the softest, and the calculated wall thickness is the smallest under the same design pressure. Under the same conditions of use and the same wall thickness series of pipes, this variety has the highest safety in use. However, the price of raw materials is the highest, more than double that of other varieties, and the current domestic application area is small. The future market will slowly popularize this kind of pipe.

The 　　 floor heating construction team stated that the floor heating material is a medium-density polyethylene with very stable mechanical properties, which is made by copolymerizing ethylene and octene monomers through metallocene catalysis. Its unique ethylene main chain and octene short-branched structure make it have the excellent toughness of ethylene, stress crack resistance, low temperature impact resistance, outstanding long-term water pressure resistance and octene heat creep resistance.

　　 The above are all kinds of floor heating pipes made of different materials by PEX Fittings Wholesale. Of course, due to the different materials, the heating performance of floor heating pipes is also different. Among all kinds of floor heating pipe materials for floor heating installation, PB pipe is the most widely used, but the price of its raw materials is also the highest, so its performance is also the most superior.
