PVC air hose pipe in the process of use due to various reasons, there will be hose explosion, bulging, bag and other phenomena. The causes of these problems may be the quality of the product, or improper use. Let’s talk about the quality of the product first.
1. The thickness of the tube wall is too thin or uneven, and bulge or even rupture will occur in the face of pressure
2. With the material formula, the material is too soft. Although the elasticity and softness are good, it is also easy to bulge and swell
3. The material problem of the middle fiber reinforcing line, the fiber line has different strengths, and the fiber line with poor strength will burst easily when the pressure is strong
It can be seen that the raw material and testing of the product are very important to the quality of the pipe. Our company uses high-quality PVC, and the testing of products is also very strict.
Then, there are other external reasons:
1. PVC hose is used for a long time, resulting in aging problem
2. Drag in the process of use, scratch by sharp tools, scratches and other problems
