The weather is getting cooler, is your home heating system ready? Are you buying so many floor heating pipes on the market?
As we all know, the pipe is an important part of the floor heating system, which is related to the normal operation and heating effect of floor heating, so the choice of floor heating pipes is sloppy. Brand aside, the next few common pipes in the floor heating introduced by Xiaobian you have to look carefully.
PERT tube
The new type of pipe (conventional polyethylene pipe) that has emerged in recent years is mainly a special linear medium-density ethylene copolymer made of ethylene and octene copolymer, and the thermoplastic pipe can be extruded with the addition of an appropriate amount of additives. It is currently the only polyethylene pipe that can be used for floor heating without crosslinking, and the comprehensive cost performance is high.
Advantages: has good thermal stability and compressive strength, easy to bend, and can be used hot melt connection, repair after damage is more convenient.
Disadvantages: poor scratch resistance, need to pay attention to protection during construction.
PEX tube
PE-X, that is, cross-linked polyethylene pipe, is currently the largest variety used in the floor heating system in Europe, and at the same time inherits the inherent chemical resistance and flexibility of polyethylene pipe, which is one of the two pipes with the largest amount of floor heating. PE-X tubes are divided into three types: PE-Xa, PE-Xb, and PE-Xc.
PE-Xa: peroxide cross-linked polyethylene pipe, the degree of crosslinking should be ≥70%, the pipe is translucent, soft, easy to bend, the price is very low in the floor heating pipe.
PE-Xb: silane cross-linked polyethylene pipe, the degree of crosslinking should be ≥65%, the appearance is milky white, due to high strength, good rigidity, hardness, should not be bent, the price is slightly higher than the upper one, and the dosage is also larger.
PE-Xc: electron beam cross-linked polyethylene pipe, the degree of crosslinking should be ≥ 60%, the appearance of the pipe is light yellow, translucent.
Performance sits somewhere in between, with the highest price among PEX pipes.
PB tube
It is a thermoplastic pipe that is extruded by polybutyrene-1 resin additive. Polybutene has a high molecular weight and crystallinity, is a high-performance resin material, known as "pipe soft gold", high quality and high price, mostly used in high-end residential.
Advantages: high pressure resistance, heat resistance, cold resistance. Light weight, good flexibility, easy to apply. It can have a service life of more than 50 years in the temperature range of -30-100 °C.
Disadvantages: higher price, general thermal conductivity.
How to choose the three kinds of pipes? From the above comparison, the following conclusions are drawn:
Specific temperature resistance: PB tube> PEX tube> PE-RT tube followed;
Specific pressure resistance: PB tube = PEX tube> PE-RT tube followed;
Specific corrosion: PB pipe, PEX pipe, PE-RT are corrosion resistant;
Specific flexibility: PB> PE-RT tube> PEX tube;
Specific thermal conductivity: PEX tube, PE-RT in general, PB tube thermal conductivity is second;
Ratio economy: PE-RT is more cost-effective than PEX tube, PB tube is the most expensive;
All kinds of floor heating pipes on the market have their own advantages, can meet the needs of floor heating, I believe that after the introduction of the small editor, you have your own program in the choice of floor heating pipes.
We can choose the right pipe according to our own consumption capacity and needs. Under normal circumstances, the market PERT tube is the most popular, the price is relatively cost-effective, if you have money and willfulness and quality requirements can choose PB tube.
