What is the heat resistance of pvc pipe?

Hard water pipes can withstand a temperature of about 70 degrees; soft PVC pipes can withstand a temperature of about 55 degrees.

1. This is only a short-term temperature resistance. If the long-term use temperature reaches the above temperature, the aging and life of the tube will be greatly lost, and the use time will be shortened.

2. PVC water pipes are very poorly resistant to high temperatures, and begin to decompose in a small amount above 90 degrees, release gas, and dissolve in water, no matter which kind is harmful to people.The standard of PVC pipes stipulates that the use temperature does not exceed 45 degrees Celsius. The performance of pipes above this temperature will drop sharply, and the higher the temperature, the easier it is to break.

3. If you discharge high-temperature water for a long time, such as over 90 degrees, you can use a cast iron drain pipe in the previous section. The drain will automatically cool down during the flow of the drain. PVC material can be used after tens of meters.
