Nowadays, there are two kinds of common floor heating pipes, one is 16 pipes and the other is 20 pipes. Depending on the specifications and installation positions of the pipes, the installation spacing of the floor heating pipes is also different. For example, the pipe spacing of general toilets is between 10cm-12cm, while the distance between the bedroom and large living room is between 20cm-25cm. PE-RT floor heating pipe is made of copolymer of butadiene monomer and octene monomer. It is a pipe specially made for heating. PE-RT floor heating pipes have the advantages of preserving PE's environmental sanitation, which can reduce environmental pollution and processing advantages, while at the same time improving the high temperature durability of a new type of special pipe material. With the improvement of people’s living standards, the utilization rate of floor heating pipes is getting higher and higher. We should understand some related knowledge of floor heating pipes, how to choose and other small knowledge, so that when the home needs decoration in the future, it can be timely and correct. Look: Observe the surface of the floor heating pipe. Touch: Touch it with your hand to feel if there is a bump on the floor heating pipe. Quantity: Looking at the level of flexibility and wall thickness, reliable floor heating pipes will clearly indicate the thickness. The floor heating pipe is likely to have no problems in the production process, but there may be some precautions for installation and transportation of PE-RT floor heating pipes. 1. If water seepage problems are found in the pipeline during the hydraulic test, the general pipe may be damaged by external forces such as fine iron wire, steel nails, spark discharge. 2. The pipes must be reinforced with ropes to avoid the occurrence of loss and other phenomena in the process of according to the freight car, but it will cause deep marks on both sides of the floor heating pipe coil.
