The pipes that can be used in the floor heating system mainly include PEX pipes, PERT pipes, PPR pipes, PB pipes, etc. Due to different raw materials and production processes, the characteristics of these types of floor heating pipes are also different. PEX pipe: good low temperature toughness, high temperature resistance, good stress crack resistance, no thermoplastic properties, can not be connected and repaired by hot melt welding, only metal pipe fittings can be used for mechanical connection; PERT pipe: retains the advantages of PEX pipe, pipe material It can be connected by hot melt, the joint is reliable, it is not easy to leak, the flexibility and low temperature resistance are very good, and the material price is moderate and the cost performance is high. It has the characteristics of good high temperature and low temperature resistance, good impact resistance, easy to bend without rebound, is the softest among several floor heating pipes, and the raw material price is higher; PPR pipe: good high temperature resistance, good mechanical properties and superior connection performance , non-toxic, hygienic, is an ideal pipe for domestic hot water and radiator systems, but due to its poor low temperature impact resistance, it is less used in floor heating pipes.
