With the improvement of consumers' diversified needs for environmental protection, health and durability of the pipe industry, China's pipe industry shows a trend of rapid development. With the increase of products, the technological progress of the industry is also accelerating. As the darling of the water pipe industry, PPR water pipe is recognized as a star pipe product with good corrosion resistance, long service life and high cost performance.

However, in the process of production, the quality of pipes is also uneven, which restricts the benign development of PPR pipes to a great extent and brings inconvenience to the construction. Therefore, how to judge the quality of PPR pipes has become a difficult problem before purchasing pipes.

After teaching you a few tips, you can have a simple understanding and judgment of PPR pipes!

1. Look at the appearance
Good PP-R water pipes have soft and uniform color, no mottled color, smooth appearance, complete marks, no bubbles, obvious depressions, grooves, impurities and other defects.

2. Touch texture
The quality of the pipe can not solve the problem, because the technology is constantly improving, and the color is not the only standard to judge the quality of the pipe. Therefore, we should touch to see whether the texture is fine and whether the particles are uniform.

3. Smell
In order to make huge profits or the production technology can not meet the requirements, some businesses choose toxic raw materials, and the produced pipes have a pungent smell, while good PPR pipes have no smell.

4. Pinch hardness
PPR pipes have high hardness and will not deform when pinched, while those pipes that deform when pinched are definitely not PPR pipes.

5. Impact elasticity
A good PPR tube has good "resilience". If it is too easy to break, it will not be a good PPR tube. However, PPR tube is brittle at low temperature. If it is in winter and the temperature is lower than 10 degrees, the best PPR tube can be broken~

6. Smoke and smell
Another intuitive way to distinguish is to select some samples of PPR tubes and burn them. If the raw materials are mixed with bad materials, the burned pipes will emit black smoke with pungent smell, while the good materials will not emit black smoke and smell after combustion. After combustion, the molten liquid is still very clean.
