PPR pipe is an important material for heating system and waterway reconstruction in home life, and PPR pipe is divided into two types of cold water pipes.
The main difference between PPR hot and cold water pipes is that withstand pressure, the withstand pressure of the cold water pipe is 1.6 or 1.0 MPa, and the withstand pressure of the hot water pipe is 2.0 or 1.6 MPa. PPR Cold Water Pipe is generally used as a water pipe. The hot water pipe is generally used as a heating pipe or a hot water pipe for a water heater. If the cold water pipe is used on a hot water pipe with a large working pressure (such as a heating pipe), the pipe wall is easily broken, but this is not absolute. Some pipes can use cold water for hot water, but no matter what. How to make hot water pipes for hot water pipes is not allowed. It is possible to use PPR Hot Water Pipe as a cold water pipe. The cold water pipe and the hot water pipe are different in pressure, the wall thickness is different, and the price is different. The hot water pipe is thicker than the pipe wall of the cold water pipe, and the price is expensive. The hot water pipe is marked with a red line. If the PPR pipe of the same specification is thicker than the wall thickness, the hot and cold water pipes can be distinguished. In addition, it is best to use a brand of hot and cold water, as well as accessories. When choosing, you should choose those tubes with soft color and oily texture. The inner and outer walls of the tube should be shiny, no bumps and cracks, and the weight should be heavier.
