Generally, ppr cold water pipes cannot be used as hot water pipes.
1. The material of the hot and cold water pipes is exactly the same, but the wall thickness of the hot and cold water pipes of the same diameter will be much different, which directly affects its pressure bearing capacity. Substitute use creates hidden dangers.
2. If the cold water pipe you use is of very good pressure bearing quality, it is also possible to be above the S4 (1.6 MPa) level.
3. PPR pipes are within the same level, and the quality and indicators of hot water pipes are better than those of cold water pipes. If cold water pipes are not enough, it is possible to install hot water pipes instead. But the hot water pipe cannot be replaced by the cold water pipe. Just like the hot water pipe can withstand the thermal expansion and contraction properties of hot water, but the cold water pipe does not consider the thermal expansion and contraction performance of hot water during the production process, so the hot water pipe can replace the cold water pipe, but the cold water pipe cannot replace the hot water. Tube.
PPR water pipe related introduction:
1. PPR is the abbreviation of English random copolymer polypropylene (Polypropylene-Random). Commonly known as three-type polypropylene.
2. PPR pipe is a replacement product of galvanized pipe, UPVC water supply pipe, aluminum plastic pipe, PE pipe, PE-X pipe and PE-RT pipe. Because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, thus becoming the main force of water pipe materials.
3. PPR pipes are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.
