Nowadays, people’s living becomes more and more better in all respects. While the water pipe changes from single to hot and cold types. Then is there any differences between them? The answer is absolutely. First of all, the wall thickness is quite different. Then the price will be different as well. Next let me show you the detailed difference.
Because the work condition and temperature are different, the material should be different as well. The material of hot water pipe should be PPR. While it’s PPB of cold water pipe.
Hot water pipe is made from PPR. Because it has better stability and mechanical property at high temperature. But it will be crisp at low temperature. Thus it’s easy to break. While PPB cold water hose remains flexible at low temperature. But if works at low temperature conditions, it will be easy to distort. Besides, the strength will reduce greatly.
Because of the different material, the stress strength is different as well. If you smash the hot water pipe with a hammer, it will crack. But cold water pipe will just turns white with external force. You can smash it to flat but it will not crack.
How to distinguish hot and cold water pipe with the same diameter and wall thickness? Generally speaking, temperature of the water inside cold water pipe is lower than freezing point. Thus it can thaws at low temperature. But you can’t roast with fire. Therefore, reduce the exposure to avoid crack and break.
In another hand, you can see the line on the surface. If it’s read, then it’s a hot water pipe. But if it’s blue, it will be a cold water pipe.
Because of the different thickness, price of hot water pipe is higher than cold one.
