As a new type of water pipe material, ppr tube has unique advantages, it is non-toxic, light weight, pressure resistance, corrosion resistance, using a special hot melt connection, will not rust, and ppr tube will not scale, Is becoming a promotional material. Next Xiaobian introduced ppr pipe specifications and ppr water pipe selection skills.
Ppr water pipe specifications
From ppr diameter specifications, common home improvement ppr specifications are: 20, 25, 32mm and other specifications. S3.2 and S2.5 hot water pipes, these two are domestic hot water pipes, PPR standard type and PPR antibacterial type, if used for heating, then use standard PPR on it.
S4 and S5 are hot and cold water pipes (PPR pipes are divided into hot and cold water pipes, the wall thickness is not the same, and cold water pipes cannot be used as hot water pipes. The simple method of distinguishing hot and cold water pipes is a red line marking on hot water pipes. Now Many home appliances use all hot water pipes.
Ppr pipe selection skills
1, "touch": whether the texture is delicate, whether the particles are uniform. At present, PPR pipes on the market are mainly in several colors of white, grey and green. Under normal circumstances, recycled plastics cannot be made white, so many people think that white is the best. In fact, this view is more one-sided. As technology has improved, color is not a criterion for discriminating PPR tubes. The quality of the pipe does not solve the problem. If it is touched, it is likely that the coarse particles are mixed with other impurities.
2, "smell": There is no smell. The main material of the PPR pipe is polypropylene. Good pipes have no odor, while bad ones have a strange smell. It is most likely that polyethylene (PE) is blended instead of polypropylene.
3, "pinch": PPR pipe has a considerable hardness, you can easily squeeze into a deformed tube, certainly not PPR tube.
4, "ç ¸": good PPR tube, "resilience" is good, too easy to break is too much calcium carbonate filler, nature is not a good PPR tube. The PPR pipe that is not broken is not necessarily a good pipe. The key is to look at raw materials and processing technology.
5, "burn": Igniting a fire, very intuitive and very useful. PPR pipes that contain recycled plastics and other impurities in their raw materials will emit black smoke and have a pungent odor; good materials will not only emit black smoke and odor after burning, but the burnt-out liquid will remain clean after burning.
Ppr hose features
1, non-toxic, health. The raw material molecules of PP-R are only carbon and hydrogen elements, and no harmful toxic elements are present. It is hygienic and reliable. It can be used not only in hot and cold water pipes, but also in pure drinking water systems.
2, insulation and energy saving. The thermal conductivity of the PP-R tube is 0.21w/mk, which is only 1/200 of the steel tube.
3, better heat resistance. The Vicat softening point of the PP-R tube is 131.5°C. The maximum working temperature can reach 95°C, which can meet the requirements of the hot water system in the building water supply and drainage specification.
4, long service life. The service life of PP-R tube can reach more than 50 years under the operating temperature of 70°C and working pressure (PN) 1.OMPa. The working life of the PP-R tube can reach more than 100 years under normal temperature (20°C).
5, easy installation, firm connection. PP-R has good welding performance. Pipes and fittings can be connected by hot melt and electrofusion. It is easy to install and the joints are firm. The strength of the joint is greater than the strength of the pipe itself.
Editing summary: About ppr water pipe specifications and ppr water pipe purchase skills are introduced here, and hope to be helpful to everyone. If you want to know more related information, you can pay attention to this website information.
