Identification method of PPR tube.

- Jul 21, 2018-

With the advent of the decorative season, many people are busy decorating their love nests. How to choose the right pipeline at the right price is very important for consumers. Most people choose the water pipe is the outside world, understand the advantages and disadvantages of various pipes, choose PPR pipe, but do not know how to choose the following formula, teach you to easily identify whether the PPR pipe is good or bad.


Touch


Whether the texture is fine and whether the particles are uniform. PPR tubes are now mainly white, gray and green in the market. Under normal circumstances, recycled plastic can not be white, so consumers tend to think that white is the best, in fact, this view is relatively one-sided. As technology updates increase, color is not a good standard for identifying PPR pipes. Whether the tube is good or bad, it does not solve the problem, touch, rough particles may be mixed with other impurities.


Smell


There is no smell. The main material of the PPR pipe is polypropylene. The good pipe has no odor, and the poor one has a strange smell. It is very likely to be blended with polyethylene instead of polypropylene.


pinch


The PPR tube has a considerable hardness and can be nailed into the tube at will, certainly not a PPR tube.



Good PPR tube, "elastic" is good, too easy to crush natural poor PPR tube. But the hardness is not equal to the flexibility. How to crush the broken PPR tube, consumers have to doubt. Because some illegal manufacturers increase the hardness of the pipe by adding too much impurities such as calcium carbonate, the pipe is prone to brittle fracture for a long time.


Burn


Ignite and burn, very intuitive and very useful. The raw materials are mixed with recycled plastic and other impurities. The PPR tube will have black smoke and a pungent smell. The good material will not burn after burning, no odor, and the molten liquid will still be clean after burning.


Generally, in the hydropower transformation, the raw water pipes will be replaced, and all the hot water pipes selected by the home enterprises and enterprises in the proposed PPR pipeline will be hot water pipes even through cold water. Their argument is that because the technical parameters of the hot water pipe are higher than the cold water pipe, the price difference is not large, so the waterway transformation is carried out with the hot water pipe. Another fact is that even if you want to buy the cold water pipeline market, it is difficult to buy, because the cold water pipeline only supplies the tool market, and does not provide the home improvement market.


Pipe diameter


The diameter of the PPR tube can be from 16mm to 160mm, and the main use in the home decoration is 20mm, 25mm (commonly known as 4-tube, 6-tube), of which 4 tubes are used more.


Wall thickness


There are two kinds of 2.8mm and 3.4mm. Dealers will say that the latter's pressure capacity is larger than the former. Some people don't think so. Since the manufacturer produces 2.8 wall thickness, it must have been experimentally certified. The water pressure it can withstand must meet the national standard. The reason why you can do it is to produce 3.4; at the same time, the thicker the pipe wall, the smaller the inner diameter of the pipe, the smaller the water flow.


The PPR pipe is divided into a cold water pipe and a hot water pipe. The difference is that the cold water pipe has a blue marking line and the hot water pipe is a red wire.
