With the continuous improvement of people's living standards, people are not only satisfied with solving the problem of food and clothing, but also gradually begin to pursue a higher quality of life. Therefore, as a new type of heating, ground heating is very popular because of its unique health function. The more families choose to install ground heating. Then the owner should pay attention to many details when choosing and purchasing the floor heating pipe material, which will save a lot of trouble in the future. Next, along with the minor knitting of the Enomei family, we will learn about the material of the heating pipe and the selection and purchase of the heating pipe material are some skills that we should master.
First of all, we need to know what the material of the heating pipe is.
1. PE-X tube
PE-Xa pipe is a kind of floor heating coil which is certified by EU, and its price is relatively high. Expanded pipe connection is adopted in construction, which is convenient to install. Its characteristics are good low temperature toughness, high temperature resistance, good stress cracking resistance, no thermoplastic properties, can not be joined and repaired by hot melt welding method, can only use metal pipe mechanical connection.
2. PE-RT tube
The advantages of PEX pipe are retained. The pipe can be connected by hot melt. The joint is reliable. It is not easy to leak. It has good flexibility and low temperature resistance. Moreover, the material price is moderate and the performance-price ratio is high. It is a common pipe used in floor heating at present.
3. PB tube
It has the characteristics of high pressure resistance, high temperature resistance and low temperature resistance, good impact resistance, easy to bend without rebound, and is the softest of several kinds of floor heating pipes. The price of raw materials is the highest, more than twice that of other varieties, and the use of raw materials is less than that of the former.
4. PP-R pipe
High temperature resistance, good mechanical properties and excellent connection performance, non-toxic and sanitary, are ideal pipes for domestic hot water and radiator systems. However, due to their poor low temperature impact resistance, they are less used in heating pipes.
When we choose to buy heating pipes, we also need to master some shopping skills in order to avoid being cheated by bad merchants.
1. Look at the appearance
Looking at the appearance of geothermal pipes, good quality geothermal pipes are smooth without bumps, bubbles, obvious color difference and impurities, and the type, specification and brand of geothermal pipes are indicated on the geothermal pipes. Good floor heating pipes have clear print and are not easy to fall off.
Use your hands to feel whether the pipe has furrows or not. Good quality pipe feels delicate, smooth and moderately soft and hard. In order to ensure the reliability of the pipeline system, floor heating pipes can not be without joints, which requires the use of the whole pipe, pipe soft enough, easy construction.
3. Looking at Thickness
Comparing the flexibility and wall thickness of geothermal pipes, the wall thickness of geothermal pipes is generally marked as 2.0. Some geothermal pipes are marked as 2.0 wall thickness, but the wall thickness of geothermal pipes with good quality can meet the requirements and is unified with the marking. When you only look at the pipe can not distinguish when you can use two kinds of pipe to compare, see which pipe wall thickness is more.
