When we were carrying out the construction, the most annoying thing was to buy a poor quality plastic pipe, which not only wastes the construction cost, but also delays the construction progress. Today, we teach you how to distinguish the plastic pipe:
1, is the "touch" texture. In general, coarse particles are likely to incorporate impurities. 
2, is to "see" the color. Plastic pipes are mainly white, gray and green. Consumers often think that white is the best. In fact, color is not a criterion for judging quality. 
3, is the smell of "smelling". The main material of the plastic pipe is polypropylene. The good pipe has no odor, and the poor one has a strange smell. It is likely to be blended with polyethylene instead of polypropylene. 
4. It is "pinch" hardness. The plastic tube has a considerable hardness, and the tube that can be pinched and deformed is certainly not a plastic tube. 5, is "砸" flexibility. A good plastic tube, "resilient" is good, easy to smash naturally is not a good plastic tube. However, the hardness is not equal to the elasticity. Some manufacturers increase the hardness by adding too much impurities such as calcium carbonate, so they are not broken, and they are easy to be brittle after a long time. 
6, is "burning" smoke smell. Plastic pipes mixed with recycled plastic and other impurities will emit black smoke and have a pungent odor. After burning a good material, not only will it not emit black smoke or odor, but after burning, the molten liquid will still be very clean.
