What kind of floor heating pipe is good to choose?
1. Material comparison
(1) PE-RT polyethylene: Polyethylene pipe is currently the most popular floor heating pipe in the market. It is a common pipe material and one of the most widely used pipe materials. It uses a new generation of floor heating pipe raw materials with excellent toughness, stress crack resistance, low temperature impact resistance, outstanding long-term water pressure resistance and octene's thermal creep resistance.
(2) PB polybutylene: The raw material of PB floor heating pipe is polybutylene, which is known as "soft gold" in plastic pipes. PB pipe is light in weight, has good pressure resistance, impact resistance, low temperature resistance and high temperature resistance, and can be used for a long time at 100℃
(3) PEX cross-linked polyethylene: The main raw materials used in the production of PEX pipes are high Density polyethylene resin, but the price of PEX floor heating raw materials varies greatly. Some domestic manufacturers use raw materials at will, making it difficult to guarantee product quality. Therefore, this point should be noted during the selection and use of floor heating materials.
2. Specifications and models
The common specifications of floor heating pipes are 16mm and 20mm in diameter. The diameter is 16mm, which is suitable for independent heating systems of wall-mounted boilers. It is used more abroad. Due to different national conditions and water quality differences, it is not used much in China at present. At present, municipal heating radiators in northern cities are being replaced with floor heating. Due to poor water quality, 20mm is mostly used.
3. Appearance comparison
Generally, the outside of good-quality pipes is relatively smooth, without bumps, bubbles, or obvious color differences, and the corresponding specifications, models, brands, etc. will be indicated with brighter writing. Clear and not easy to fall off.
4. Color selection
The actual role of color is not as big as we imagine. The quality of pipes depends on the raw materials and their production processes. It is just the addition of pigments to the raw materials. It's just an agent and has nothing to do with the color.
5. Imported vs. Domestic
Imported brands are basically PEX pipes with stable performance and long life. Therefore, if you pursue quality, choose imported floor heating pipes, and choose domestic pipes of imported brands for cost-effectiveness. Relatively high. Domestic floor heating pipes are relatively low in terms of standard and performance quality.
