PPR cold and hot water pipes are commonly used materials in modern building water supply systems, mainly made of polypropylene random copolymer (PPR), widely used in cold and hot water supply systems in households and public buildings.PPR pipes are the updated products of PVC pipe, aluminum-plastic pipe, HDPE pipe, PE-X pipe, and PE-RT pipe. Due to its use of random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, making it the main force of water pipe materials.
The difference between cold and hot ppr water pipe：
The difference between PPR cold and hot water pipes is mainly reflected in their pressure resistance and wall thickness. Hot water ppr pipes have a higher pressure resistance rating compared to cold water pipes, so the wall thickness of hot water pipes will be thicker under the same diameter. For example, commonly labeled pipes with S5 (PN10) are only suitable for cold water systems, while pipes with S2.5 (PN20) or S3.2 (PN16) can be used for both cold water and hot water systems.in daily life, while hot water pipes can be used to transport high-temperature water, such as water pipes for heating and water heaters.
Technical parameters and applications
The technical parameters of PPR water pipe include but are not limited to density, elastic modulus, coefficient of thermal expansion, thermal conductivity, etc. In practical applications, PPR pipe fittings are used in various fields such as cold and hot water pipes in residential buildings, pure water transmission pipes for clean water, hot water circulation and heating pipes. Especially in HVAC systems, PPR pipes are widely used due to their high temperature resistance.
Installation and Maintenance
The installation of PPR pipes usually adopts the method of hot melt connection, which is simple, fast, and firmly connected. The joint strength is higher than the pipe itself, ensuring the sealing and safety of the system. In terms of maintenance, PPR pipes usually do not require frequent maintenance due to their durability, thereby reducing long-term operating costs.
Summary
Hot and cold water PPR pipe and fittings play an important role in modern buildings and water treatment systems due to their excellent performance and wide applicability. Whether in households or public buildings, PPR pipes can provide stable and reliable water supply services, while also meeting high standards for environmental protection and hygiene. When selecting and using PPR pipes, appropriate choices should be made based on actual needs and application environments to ensure the best performance and longest service life of the system.
