PPV pipe
PPV pipes are widely used in industrial and residential buildings, sanitary drinking water supply and hot water heating. PPV pipes are divided into two types: cold and hot water pipes. The wall of cold water pipe is thin and the wall of hot water pipe is thick, so the performance of hot water pipe is much better in terms of fracture resistance, and the price of hot water pipe is more expensive than that of cold water pipe. For the sake of safety, many manufacturers have cracked hot and cold water pipes during construction to improve the safety factor.

2. Common application of PPV pipe
1. High temperature and high pressure resistant PV pipes, pipe fittings bear water pressure of 45kg/cm2 at room temperature, and the pipe deformation free temperature is 112 ℃ 2 Economical Because of the simple construction, there is no contradiction and impact with other projects, the construction period is shortened, and the construction cost is 60% less than that of copper pipe, which has superior economy. 3. The pipe fittings are corrosion-resistant and suitable for areas with high corrosion resistance requirements such as chemical plants.
3. Development history of PPV pipe
Expert suggestion: let skilled workers who have received professional training to operate. At the same time, the process flow is also very important. According to the principle of horizontal and vertical, a deep groove larger than the diameter of the water pipe shall be cut on the floor of the room foundation, and then PPV water pipes shall be laid, followed by sequential hot-melt connection. After all PPV interfaces are fused together by hot melt technology, the pressure test shall be carried out for more than 24 hours. If the site environment allows, the pressure test time can be longer. Landfill after ensuring that there is no water leakage.
