【 Weak current College 】 decoration must know knowledge of PPR pipes
All new home decoration, especially in the water this piece, you will use to PPR pipe, now available in the brand so many, but you have learned how to distinguish the quality is good or bad? if you used the wrong product, home to become a flood plain, then not only expensive, but also the mood. You should understand some knowledge of PPR. These are necessarily need to know about:
1, PPR stuff.
PPR's chemical name for copolymer, as can be seen in its material form the polypropylene copolymer for gas, technology, it is a synthetic chemical materials. Market, the best raw material supply from PPR, Europe's no. 2 provider is Korea, China is no good-quality raw materials suppliers of PPR. Therefore, select the PPR pipe, then ask your PPR raw materials are from? due to cost factors, and indeed manufacturers select the raw material, but Korea unscrupulous manufacturers you will select the recovery of waste reprocessing. So, see the color you'll know about it.
2, the difference between hot and cold water pipes PPR.
Hot and cold water pipes of different wall thickness, can bear pressure, cold water pipe is 16 kg, hot water pipe is 20 kg. The thermal conductivity, they are not the same, cold water and hot water pipes can pass, cold water pipes should not pass the hot water. There are hot and cold pipes, mainly because of the cold water pipes require less, so can offer lower prices. If economic conditions permitting, all purchased using hot water pipe is the best strategy.
3 some of the features of the PPR.
A, health. Material exclusively by carbon, hydrogen, it is not added to any toxic heavy metal salt additives.
B, heat resistance, good insulation properties. Maximum use temperature up to 95 ° c, transient temperature up to 110 ° c, the long-term working temperature of 70 ° c, could be used as a hot water supply system of pipes, pipe thermal conductivity coefficient of only 1% of the second, has good insulation properties. PPR pipe in the rated temperature and pressure, long service life up to 50 years. PPR pipes, pipes for 50 years, and is achievable.
C, pipe connections. As a result of pipe, pipe fittings are made of uniform raw material processing, integrated hot-melt connection tubing, fittings, connecting parts accessories and pipe melt into a solid overall, the intensity is greater than the strength of the pipe itself, permanently eliminate water leakage risks.
D, green environmentally friendly, recyclable. Production, construction, used in the process without any pollution to the environment, and will not cause pollution. Production and construction waste to recycling, or you can directly use the reproduction of pipes and fittings. However, due to the inevitable dependence has not waste solid impurities, it can produce things color is certainly not pure.
4, correct identification of PPR pipe pros and cons of the method.
A look at PPR pipes: high quality soft colour and texture of oil, poor quality water mixed with the PPR due to poor quality plastic even lime powder, its colour is not natural, cut section dry oil free texture, so I feel like joining the chalk.
2 touch the PPR pipes: high quality both inside and outside wall smooth, no bump crack, inferior PPR pipe inner wall rough sense of a bump.
Three OK: PPR pipes using hand quality fixed weigh weight than inferior PPR pipes to PPR pipes, inferior than high-quality light some, due to the high quality of most metal fittings for PPR with three or more waterproof leakage grooves of copper (CU content greater than 50 per cent), the longer the copper parts dimensions, thickness also thicker, so-to-weight ratio inferior PPR pipes to some.
4 burning: high-quality raw materials of PPR is a hydrocarbon chain compounds, flame temperature higher than 800 ° c above, the ideal combustion case and sufficient oxygen conditions, Burns, only carbon dioxide and water vapour release, burning should be no smell and residue, but the poor quality of PPR pipes due to mixing with inferior plastics and other impurities, combustion will smell and residue. From PPR pipe cut thin slices with a lighter combustion to identification.
Don't forget-quality, it is actually more important than the pipe, so choose the accepted norms of brand-name products.
