How to identify the advantages and disadvantages of PVC steel wire hose?
If it is necessary to identify the pros and cons of PVC steel wire hoses without professional testing tools and conditions, we can roughly distinguish the quality of PVC steel wire hoses based on the differences in vision, smell, touch, etc. quality.
1. Observe the uniformity and thickness of the pipe wall of the PVC steel wire hose. The inner wall and outer wall of a good PVC steel wire hose present a standard circular ring-shaped wall, and the thickness is evenly distributed.
2. Observe through the eyes whether there are bubbles or other impurities visible to the naked eye on the pipe wall of the PVC steel wire hose, and observe the transparency of the pipe wall. Good quality PVC steel wire hose should be transparent and free of impurities. The poor quality hose wall will contain some impurities or yellowing.
3. Distinguish the quality of PVC steel wire hose by smell. Generally, high-quality hose has only a little plastic smell and no smell of any other petrochemical products.
4. By touching the hose, the wall of the good-quality PVC steel wire hose is smooth and feels good, while the poor-quality one will be rough.
5. It can be seen from the measurement that the wall thickness of the good-quality hose is uniform, and the pipe wall can be intercepted from three different places to measure the thickness to check whether the data is consistent.
