Method to Analyze the Quality of PVC Steel Wire Hose

How to judge the quality of PVC steel wire hose

1. Use professional equipment to test the heat deformation temperature or Vicat softening point, chromaticity, turbidity, resistance to positive and negative pressure, explosion pressure, halogen, nitrate content, and tensile strength of PVC steel wire pipes.

2. Investigate whether the wall thickness of the steel wire pipe is uniform. The uneven thickness of the pipe wall will cause easy cracking and explosion during use, which will seriously shorten the service life of the PVC steel wire hose.

3. Investigate whether there are bubbles, pastes, etc. on the pipe wall.

4. The odor of high-quality PVC steel wire hose is very small, except for the weak plastic smell, there is no pungent odor like petroleum additives, on the contrary, the smell of low-quality steel wire hose is nasty, using a lot of recycled materials and chemical raw materials It is added, especially when the temperature is high, and the bottom is not close.

5. Take a section of steel wire from the cut surface of the PVC steel wire hose to do an experiment to see if it is easy to break. A good quality steel wire needs to be cut by professional tools. In addition to ensuring its flexibility, a good quality steel wire tube needs to be added. Its tensile strength.

6. High-quality steel pipes, smooth inner and outer walls without particles, relatively even distribution of steel wires and high density, on the contrary, low-quality steel pipes feel rough and have low transparency.
