Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes,PPR pipes have the advantages of energy saving and material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, easy construction and maintenance, and long service life. It is widely used in construction, municipal, industrial and agricultural fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation, etc.
In daily life, we can distinguish the true and false of PPR pipes through the following aspects.
Whether the texture is delicate and the particles are uniform. Nowadays, PP-R pipes on the market mainly have several colors of white, gray, and green. Under normal circumstances, recycled plastic cannot be made white, so consumers often think that white is good. In fact, this view is more partial. With the improvement of technology, color is not the standard for distinguishing the quality of PP-R tubes. Whether the tube is good or bad, it seems that the problem cannot be solved. If you touch it, the coarse particles are likely to be mixed with other impurities.
There is no smell. The main material of PP-R pipe is polypropylene. Good pipes have no odor, and poor pipes have strange odors,it may be blended with polyethylene instead of polypropylene.
The PP-R tube has considerable hardness, and if the pipes can be squeezed into a deformed tube easy it’s definitely not a PP-R tube.
A good PP-R tube has good "resilience" and it is not a good PP-R tube if it is too easy to break. But strong hardness does not mean good elasticity. Consumers will have doubts about PP-R pipes that cannot be broken. Because some unscrupulous manufacturers increase the hardness of the pipe by adding too much calcium carbonate and other impurities, such pipes are prone to embrittlement after a long time.
The ignition is intuitive and very useful. PP-R pipes mixed with recycled plastics and other impurities in the raw materials will emit black smoke and have a pungent odor; after a good material is burned, it will not emit black smoke and odorless, and the molten liquid is still very clean after burning.
