First, the performance of stable PE-X pipe (cross-linked polyethylene pipe)

PE-Xa tube is required to use the EU to warm coil, the price is relatively high. Construction using expansion pipe connection, a few seconds to complete the connection.

Pipe Features:

1, stable performance

2, is the use of the largest heating pipe

3, there is no thermoplastic properties, can not be hot-melt method of connection and repair

Price: PE-Xa tube 25 yuan / meter, imports should be high 20-30 yuan / m; PE-Xc tube does not add additives, raw materials, low cost, the price is generally 20 yuan / m.

prompt:

1, PE-X tube is currently in Europe to use the floor heating system in a pipe. Production with cross-linking agent is not easy to spread evenly, the degree of cross-linking is difficult to control and need to regularly clean the screw to prevent the formation of gel particles and other difficulties, so the product quality control more difficult, the general small-scale production enterprises difficult to do.

2, to warm the difference between the price of raw materials, some domestic manufacturers of random raw materials used at random, so that product quality is not guaranteed, in the choice of low-priced products when a certain degree of risk.

Second, the high price of the PB pipe (polybutylene pipe)

By the environmental protection function of the thermoplastic material made of PB pipe molecular structure stability is very good, put an end to the phenomenon of corrosion and scaling, non-toxic harmless. Fully in line with the national drinking water health standards.

Pipe Features:

1, good thermal stability

2, excellent flexibility

3, the price is expensive.

Price: generally 120 yuan / m. Imported to your 30 to 60 yuan.

prompt:

1, PB tube is a high polymer, is the world's most advanced chemical materials. It is a thermoplastic pipe, has a good temperature resistance, the maximum temperature of up to 110 degrees, good impact resistance.

2, PB pipe is a few to warm the most soft pipe, the same design pressure wall thickness is also the thinnest pipe. In the same conditions of use, the same series of wall thickness, the safety factor is relatively high.

3, aluminum-plastic composite tube to overcome the traditional metal tube short life, rust and other shortcomings and other shortcomings. It is easy to bend without bouncing characteristics to make it easy to locate in the construction, the construction of the difficulty and intensity than the pure plastic tube is much lower efficiency. But the price "high above", not many people in the domestic use.

Third, the most cost-effective PE-RT pipe (heat-resistant polyethylene pipe)

PERT pipe heat resistance worse than the PEX, the general water temperature can not exceed 70 degrees, if the water temperature is too high, life will be reduced. PERT tube used in the warm, as long as the water temperature does not exceed 60 degrees, is a good tube.
