PE water supply pipe is a common water supply pipe, because of its good flexibility and high pressure resistance, has become the favorite of modern water supply and drainage. In addition, PE water supply pipes are made of white, non-toxic, flexible raw materials, which are used in many engineering projects.
But sometimes found pe water pipe surface rough, not up to the standard. It should be known that there are many reasons for rough pipe surface. Therefore, only when the root cause is clear can targeted solutions be adopted to give PE feed pipes a high quality surface.
1. If the PE water pipe is made of new materials, it can eliminate the reason that the water in the raw material leads to the rough surface of the pipe; If the roughness of the PE feed pipe is only present in a very thin surface layer, it may form in the die section.
2. The surface roughness of PE water supply pipe is caused by the friction between melt and mold surface, and has nothing to do with mold surface roughness.
3.For high viscosity polyethylene, due to the strong entanglement between molecular chains, the surface of PE water supply pipe is very rough, not easy to separate from the melt, can not form effective lubrication. So, if you want to get smooth, you have to add another lubricant.
What should we pay attention to when installing PE water pipe?
Although PE water supply pipe is only a plastic pipe product, it also involves various safety problems in the installation process. PE Water pipe installation precautions.
1. When installing pe water supply pipe, the voltage of installed equipment must be measured after loading; At the same time, the housing must be grounded to ensure personal safety.
2. After measuring the voltage of the device, the voltage of the grid and the generator should be measured to ensure that the voltage is always maintained at 220 volts to prevent damage to the machine.
3. Because PE water pipe connection needs heating process, heating plate temperature indicator light should be lit to ensure welding temperature.
