Advantages and Disadvantages of Pexa Pipe

Release time：

2024-10-03

The cross-linked polyethylene PEXa pipe is mainly made of high-density polyethylene XL-1800 provided by LG Chem in South Korea. Through cross-linking, chemical covalent bonds are formed between polyethylene molecular chains, resulting in a three-dimensional network structure of molecules. It has excellent high temperature resistance, pressure resistance, and other physical and chemical properties. Due to its high cost-effectiveness, it has become the preferred pipe for ground heating systems.

Advantage

High and low temperature resistance: PEXa pipes have excellent high temperature resistance, able to withstand temperatures up to 95 ° C, and can operate normally at low temperatures of -40 ° C.

Thermal conductivity: The thermal conductivity coefficient of PEXa pipeline is as high as 0.4W/m.k, and there is no scaling during thermal conductivity and no frosting during cooling.

High cross-linking degree: PEXa pipes have high cross-linking degree, hard and tough texture, and excellent chemical corrosion resistance.

Easy to bend: PEXa pipes are easy to bend and suitable for use in underfloor heating systems, making them easy to construct.

Easy connection: PEXa pipes can be connected quickly and easily, with simple and convenient connections that can be completed in just ten seconds.

Disadvantage

Slow production speed: The biggest disadvantage of using synchronous cross-linking method to produce PEXa pipes is the slow production speed. Taking dn20x2.3 as an example, the pipe line speed is 1.3-1.4m/min, resulting in low production efficiency.

Conclusion

PEXa pipes are widely used for the transportation of hot and cold water as well as various chemical liquids due to their superior performance, especially in floor heating, and will gradually become the most competitive pipe material among hot water pipes.
