How to judge the quality of PVC flexible hose pipe

In life, we often use PVC flexible hose pipes, which are water pipes. PVC flexible hose pipe can be used in many fields. But every time it breaks after a short period of time, it's because people don't know how to distinguish PVC flexible hose pipes. Next, I will teach you how to distinguish the quality of PVC flexible hose pipes.


The PVC flexible hose pipe is made of environmentally friendly PVC rubber particles, which are dried and heated by the extruder, extruded and formed, cooled, and then packaged in rolls. PVC flexible hose pipes can be customized in various specifications, sizes and colors according to needs.


The PVC flexible hose pipe is soft, wear-resistant, acid-resistant, cold-resistant, corrosion-resistant, and oxidation-resistant. The PVC flexible hose pipe has excellent flame retardancy and electrical insulation. The working temperature is -30℃ to 105℃. The application range of PVC flexible hose pipe is very wide.


PVC flexible hose pipes have a wide range of uses. PVC flexible hose pipes can be widely used in electronic components, home appliances, automobiles, machinery, toys, cultural and sports goods and other fields. This has also led to a large number of unqualified PVC flexible hose pipe products flowing into the market, and people spend money on bad products, and the quality of PVC flexible hose pipe products is still very poor.


1. The quality of PVC flexible hose pipes


(1) Measure the wall thickness

To see whether the PVC flexible hose pipe reaches the specified wall thickness, there is one more thing to pay attention to here. Some pipes are vacuumized, and the wall thickness at both ends of the PVC flexible hose pipe meets the requirements, but the middle wall thickness is relatively thin, which does not meet the requirements for use. At the same time, vacuuming the PVC flexible hose pipe reduces the cost.


(2) Measure the length

To see whether the PVC flexible hose pipe reaches the required length, some PVC flexible hose pipe manufacturers reduce the price by shortening the length. According to GB/T10002.1-2006, no negative deviation of PVC flexible hose pipe is allowed.


2. Look at the PVC flexible hose pipe


(1) Look at the gloss: The product with good gloss and oiliness on the surface of the PVC flexible hose pipe is a good product.

(2) Look at the color: the standard PVC-U pipe is light beige. If the PVC flexible hose pipe is white, it means that the calcium powder has been added too much. Some PVC flexible hose pipe manufacturers add too much miscellaneous materials and recycled materials to make the pipe black and yellow.


3. Weigh the PVC flexible hose pipe


Weigh: Compare the weight of two PVC flexible hose pipes with the same diameter, wall thickness, and length. If calcium powder and heavy impurities are added too much, the material is not pure, and it does not meet the requirements of PVC flexible hose pipe.


4. Throw the PVC flexible hose pipe


If possible, you can step on the side of the PVC flexible hose pipe with your foot to see if it breaks easily. Pick up the PVC pipe and throw it to the ground.


If the pipe breaks, then it has been added with too much calcium powder, and some PVC flexible hose pipe manufacturers are profitable in this way. Too much calcium powder is added to the pipe production. This kind of PVC flexible hose pipe is cheap, but the hardness is much lower, and it is fragile, which is a substandard PVC flexible hose pipe product.
