There are many kinds of PVC hoses on the market. Among PVC steel wire hose is a common one. Compared with ordinary PVC hose, there are more spiral steel wires inside. These steel wires play a very important role in fastening. So how to identify its quality?
The identification skills of PVC steel wire hose
1. Check the inner wall and thickness. The inner wall and outer edge of a good quality PVC steel wire hose are regular and circular. And the thickness is evenly distributed.
2. Check the inner wall for air bubbles. The wall of a good PVC steel wire hose is transparent without any air bubbles or impurities. There will be air bubbles or impurities if the quality is poor. If the color of the hose is yellow, it means that its quality is also problematic. This may be caused by production, transportation or storage.
3. Smell. A good hose has no irritating odor except for a little plastic odor. However, the inferior has an unpleasant pungent odor.
4. Touch. Good hose has smooth walls. Instead, poor hoses are rough.
5. When measuring the thickness, you’d better select the intermediate tube. This can ensure accurate measurement.
6. PVC steel wire hose has high strength and good flexibility. You can repeatedly folding the wire. If it is not easy to break, it’s good quality.
