Plastic water pipes are made of high molecular polymers, and different materials determine the different characteristics of plastic water pipes. In order to choose the right water pipe, we must first understand the classification knowledge of plastic water pipes. The following small series introduces you to the introduction knowledge.
First, the type of plastic water pipes
Plastic water pipes are divided into materials according to materials, which can be divided into UPVC (hard polyvinyl chloride), PPR (random copolymer polypropylene), PE-RT (heat resistant polyethylene), etc., each of which has its own advantages and disadvantages and applies. range.
Plastic water pipes are divided into three types according to their use: water supply pipes, drainage pipes, and floor heating pipes. The water supply pipe requires the water pipe material to be environmentally friendly and non-toxic, and meets the requirements of human health; the drainage sewage pipe has lower requirements on the material of the water pipe, but the diameter of the water pipe is required to be larger; the floor heating pipe requires the water pipe to withstand high temperature and high pressure, and does not deform or leak.
Second, the specifications of plastic water pipes
Plastic water pipes vary in size depending on the application. The three common sizes of plastic water pipes are listed below.
The length of the plastic water pipe is 4m or 6m, and other sizes need to be customized. Plastic hose outer diameters and wall thickness specifications are much richer than length specifications. PE-RT pipe is mainly used as floor heating pipe, so the outer diameter wall thickness size and specifications are small; UPVC is mainly used as drainage sewage pipe, which has large size and choice; and PPR has wide application range, so the pipe outer diameter wall thickness The specifications are more concentrated, and even derived from the common name, such as D25*3.5, the outer diameter is 25mm, and the wall thickness is 3.5mm, which is called 6-pipe.
Third, the price of plastic water pipes
Different materials of plastic water pipes and production processes are different, and the price will of course vary greatly.
The total cost of plastic water pipes refers not only to the price of the pipe itself, but also factors such as pipe fittings, connecting tools, installation man-hour costs, pipe loss ratio, and maintenance period of installation reliability. Therefore, consumers should compare them according to the above comprehensive indicators. Due to the wide variety of plastic water pipes and the large price difference, many consumers will fall into the wrong buying habits.
