In most cases, we have no way to quickly learn about PVC steel Wire Hose, which allows us to buy inferior products and waste a lot of time and money. So how do we identify it? We can based on our sense, touch and smell. Now,we will share it with you.
Methods of identification:
We know that the PVC Steel Wire Hose has different wall thickness, so we could observe whether the lumen is regular and whether the wall thickness is uniform:The inner cavity and outer edges of good quality PVC Steel Wire Hose is standard round with evenly distributed ring walls.Take the PVC Steel Hose with inner diameter of 89mm and 7mm wall thickness as an example, the poor tube wall can reach 7.5mm thicker and 5.5mm thinner. Under large pressure, it is easy to burst or deform the PVC Steel Wire Hose, affecting the normal use.
We can observe whether bubbles or other objects are visible to the wall, and whether they are colorless and transparent:The wall of the high-quality PVC Steel Wire Hose is transparent, without any impurities, while the secondary product’s color is yellow, which may be caused by some decomposition due to improper treatment, aging, or long-term improper storage in the production process.
Outer wall of the high quality PVC Steel Wire Hose is smooth and has good feel, while the low quality tube is rough.
High quality products without any other petrochemical smell,while the inferior products have an unpleasant and pungent diesel smell, especially in the hot summer, people are not close to.
When measuring the wall thickness, the two ends of the PVC Steel Wire Tube should be cut off, and the middle tube should be selected as the sample test.
Several centimeters of wire were cut at both ends of the PVC Steel Wire Hose and folded repeatedly to detect the strength and toughness.Poor quality wires break when folded one or two, while wires with high quality PVC Steel Wire Hose require special tools to truncate.The quality of the wire determines the quality of the entire tube.
