Now, 90% of households use PPR pipes for water and electricity decoration, but many owners do not know that PPR pipes are divided into hot and cold water pipes. The reason is very simple. In order to facilitate construction, the water and electricity masters only install PPR water pipes in the order of materials, and rarely install PPR pipes. Cold water pipes, after all, PPR hot water pipes can completely replace PPR cold water pipes. After a long time, PPR cold water pipes are rarely seen in the home improvement market. In this way, are PPR cold water pipes eliminated? Of course not. The cost of PPR cold water pipes is lower than that of PPR hot water pipes. Cold water pipes are still very useful in real estate or other pipeline projects.
The same point of PPR cold water pipe and PPR hot water pipe: they are all made of random copolymer polypropylene material, the material properties are the same, the production process is the same, they are safe, non-toxic, green and environmentally friendly, and they can be used in specified environments. Safe use for 50 years.
The difference between PPR cold water pipe and PPR hot water pipe
1. Different appearances: PPR cold water pipes are marked as cold water pipes, which are used for cold water systems with a temperature not exceeding 20°C, and the markings are blue; PPR hot water pipes can be used for cold and heat in building life at 5°C to 75°C Water system, marked in red.
2. Different outer packaging: The general outer packaging of PPR cold and hot water pipes produced by pipeline manufacturers has obvious differences. Generally, the outer packaging bags of PPR cold water pipes are mostly blue and green according to different specifications, and the outer packaging of PPR hot water pipes are mostly red.
3. Different prices: PPR hot water pipes of the same diameter are more expensive than cold water pipes.
4. Different wall thickness and different pressure: the wall thickness of the PPR hot water pipe of the same diameter is thicker than that of the cold water pipe, and the acceptable pressure levels are also different, such as: S3.2 dn20*2.8 and S4 dn20*2.3 In contrast, S3.2 is a hot water pipe, a pipe with a DN20 diameter, the wall thickness is 2.8mm, and the pressure is 2.0MPa; S4 is a cold water pipe, a pipe with a DN20 diameter, the wall thickness is 2.3mm, and the pressure is 1.6MPa.
