1. The appearance of the tube is very important. Just like when we usually buy clothes and shoes, there are many threads and the workmanship must be rough. The same is true for PP pipes, if the appearance is rough, flawed, the color is not correct, uneven, the product model and brand printing is not complete, or the printing quality is poor, it is recommended not to use. Although it cannot be said that this kind of tube is fake, it is difficult to be reassured at least in terms of quality.
2. Due to the basic material of plastic products, they have a certain smell, so the PP pipe must smell the smell. Some profit-seeking specialists use recycled materials or poor-quality chemicals that create a lot of odors. Such plastic products must be inferior products, and there are many hidden dangers in later use, so they should not be used.
3. Touch the real PP pipe products with your own hands. Some industrial pigments are added to the production of some PP pipes, and the colors of PP pipes are bright and dazzling. When encountering PP pipes with non-material colors, you can use a absorbent cotton ball with a little vinegar, wipe it back and forth, and wipe it several times. If the color fades, this product is not recommended.
