What is the difference between the ppr hot water pipe and the ppr cold water pipe?
PPR tube temperature tolerance is 95 degrees, 110 degrees up to the moment, the memory of water under the condition of not less than 0 degrees, otherwise the water ice may put the pipe donglie. The withstand pressure of the cold water pipe is 1 or 1.6 MPa, the resistance of the hot water pipe
The pressure is 1.6 or 2 MPa; generally used tap water pipe PPR cold water, usually used for heating hot water pipe connecting pipe, but also can be used for hot water pipe water heater; cold water pipe and water pipe pressure of different cold tolerance.
The tube should be small, therefore, if the cold water pipe in large working pressure (such as heating hot water pipe on the connecting pipe) is easy to cause the pipe wall rupture, but this is not absolute, some of the cold water pipes for hot water can also endure,
But no matter how cold water tube hot water pipe is not allowed, the hot water pipe can be useful when cold water; cold water pipe and water pipe because of the requirement of different wall thickness tolerance pressure so different, the price is different, than the cold hot water pipe
The pipe wall thickness, the price will be more expensive, so use hot water when cold water pipe works is not cost-effective in the economy; the hot water pipe identified on the red line, the cold water pipe was labeled with the blue line, a logo and, also have pressure tolerance identification,
In addition, if the pipes of the same size compare the wall thickness, the hot and cold water pipes can be distinguished;
