Polypropylene pipes for heating and water supply

Previously, plumbing and heating were made exclusively of metal. Now technologies are developing, so new materials have begun to appear. Nowadays, metal-plastic and polypropylene pipes are most often used for heating. However, polypropylene has a number of advantages. Due to constant heating and expansion, metal-plastic fittings can unwind. Polypropylene pipes do not have such problems, since the connection is made by welding with a special device. The diameter of the pipes can be different. A pipe with a diameter of 20mm is mainly used for water supply. For heating, the pipe can be 25, 32, 40 mm or more, depending on the area of the room.



Polypropylene pipes can be reinforced and non-reinforced. The difference is that reinforced ones need to be installed on hot water and heating. Reinforcement can be external or internal. If you choose an external one, it will have to be cleaned before welding. Non-reinforced pipes are only suitable for cold water. Polypropylene fittings are all non-reinforced. These are various couplings, corners, tees, contours, crosses, and so on. Supports are used to secure the pipe. There are adapter couplings for the transition from polypropylene to metal. All this makes it easy to assemble any heating system. But for this you need to be able to use a welding machine.



To begin with, nozzles of the required diameter are put on it. Then you should cut the required length of pipe with special scissors. After that, the device needs to be heated. A fitting is placed on the nozzle on one side, and a pipe on the other. This should be done very smoothly, smoothly and carefully. There are special marks everywhere so that everything can be welded smoothly. There is a specific heating time for each diameter. For example, for a pipe with a diameter of 20mm, you need to wait 6 seconds for welding, and then connect for 4 seconds. A pipe with a diameter of 32mm needs to be boiled for 8 seconds and connected for 6 seconds. It is worth noting that the time may be longer if the ambient temperature is less than 20 degrees. If the polypropylene is removed from the nozzle too early, it may not melt well. If you hold it for too long, it will be problematic to insert the pipe into the fitting.



Polypropylene has a number of advantages over other materials for plumbing and heating. It is durable, does not rust, has good throughput, can withstand high temperatures, and is resistant to many chemical compounds. In addition, it is easy to transport and store. 1xbet รหัสโปรโมชั่น
