Good Performance Floor Heating Pipe

PEX pipes are widely used in various applications such as cold and hot water piping, oil piping, fuel tanks, and chemical piping due to their stability, durability, and resistance to vibration and impact. They also exhibit excellent hydraulic properties, making them a reliable choice for many piping systems.

There are indeed significant differences in the performance of floor heating pipes of different materials. The following is the performance comparison of several common material floor heating pipes:

Polybutylene pipe (PB pipe) :

• Advantages: PB material has excellent performance and is known as "plastic gold". Its flexibility is the best in the floor heating pipe, good heat resistance, can withstand high temperature hot water cycle for a long time, strong durability, anti-aging, long service life. In addition, the PB tube also has a certain flexibility and is easy to install.
• Disadvantages: The price is high, and it is the most expensive of all floor heating pipes.

Crosslinked polyethylene pipe (PEX pipe) :

• Advantages: Good low temperature toughness, good stress cracking resistance, excellent high temperature resistance, long-term use temperature up to 95℃, short-term can withstand high temperature above 110℃. Strong pressure resistance, can withstand high pressure, suitable for high-rise buildings. In addition, the PEX pipe also has the advantages of long life and small thermal expansion coefficient, which can reduce the problems caused by expansion and contraction of the pipe.
• Disadvantages: Thermal conductivity is relatively poor, and the price is high.

Heat-resistant polyethylene pipe (PE-RT pipe) :

• Advantages: corrosion resistance, creep resistance, good thermal conductivity, the most widely used in the floor heating pipe. Its softness is good, no special tools are required during construction, and the processing cost is relatively low. Good thermal conductivity, thermal conductivity of PP-R, PP-B pipe twice, very suitable for floor heating. In addition, the low-temperature impact resistance of PE-RT pipe is also relatively good, and the pipe is not easy to be cracked by impact during winter construction.
• Disadvantages: The price of raw materials is high, which is more than double that of other varieties.

Polypropylene tube (PPR tube) :

• Advantages: Low price, good high temperature resistance.
• Disadvantages: It is difficult to bend during floor heating construction, and the thermal conductivity is poor.

Multilayer composite pipe (such as PEX-AL-PEX pipe) :

• Advantages: The structure is stable and the aluminum layer provides rigidity to ensure the stable shape of the pipeline. At the same time, it combines the high temperature resistance of PEX tube and the pressure resistance of metal tube. Low coefficient of thermal expansion, easy to install and operate.
• Disadvantages: The bending radius is large, the construction is difficult, and the price is high.

In summary, there are obvious performance differences in floor heating pipes of different materials in terms of flexibility, heat resistance, pressure resistance, thermal conductivity, price and so on. When selecting the floor heating pipe, the most suitable pipe material should be selected according to the specific installation environment, use needs and budget.
