Do you know how to distinguish the advantages and disadvantages of PVC STEEL WIRE HOSE?

In most cases, we can roughly identify the quality of PVC STEEL WIRE HOSE according to visual, olfactory and tactile senses without any detection tools or conditions.
1. Observe whether the lumen is regular and the wall thickness is uniform. Good quality PVC STEEL WIRE HOSE has a standard circular tube wall with uniform distribution inside and outside. Taking PVC STEEL WIRE HOSE with 89 mm inner diameter and 7 mm wall thickness as an example, the thickest part of the pipe wall with poor quality can reach 7.5 mm and the thinnest part is only 5.5 mm. It is easy for the pipe wall to work under high pressure, which will lead to the bursting or deformation of the PVC STEEL WIRE HOSE and affect its normal use.
2. Observe whether there are bubbles or other visible substances in the wall of PVC STEEL WIRE HOSE pipe. The wall of high quality PVC STEEL WIRE HOSE is clear and transparent without any impurities. The color yellowing of inferior PVC STEEL WIRE HOSE may be caused by improper decomposition, aging or long-term improper storage in the production process.
3. High-quality PVC STEEL WIRE HOSE has no odor of any petrochemical products except a little plastic odor. And the bad steel pipe has unpleasant and pungent smell of diesel oil, especially in hot summer, people can not get close to it.
4. The inner and outer walls of high-quality PVC STEEL WIRE HOSE are smooth, and the low-quality tubes are rough.
5. When measuring the wall thickness, we should cut off the two ends of PVC STEEL WIRE HOSE and select the middle pipe as the sample to test, so as to prevent some illegal manufacturers from making articles on the two ends of the pipe that the actual wall thickness is thinner than the two ends of the pipe.
6. The strength and toughness of the steel wire were tested by repeatedly folding the steel wire with several centimeters cut at both ends of the PVC STEEL WIRE HOSE. The steel wire of poor quality will break when folded one or two times, and the steel wire of high quality PVC STEEL WIRE HOSE needs special tools to cut. The quality of steel wire determines the quality of the whole pipe. PVCSTEEL WIRE HOSE is prone to irreversible deformation due to the quality problems caused by steel wire.
