In most cases, there is no detection tool and testing conditions? We can according to the visual, olfactory, tactile and other sensory rough identification of Pvc steel wire hoses quality.
1. observe the lumen is rules? Wall thickness is uniform. Good quality Pvc steel wire hoses cavity and the outer edge of the standard round? Ring wall distribution evenly. To diameter 89mm? Wall thickness of 7mm Pvc steel wire hoses as an example?
Poor quality of the thickest wall to reach 7.5mm? The thinnest at only 5.5mm? Working under a large pressure? Is easy to pipe wall uneven force caused PVC hose burst or deformation? Impact of normal use.
2. Observe the presence or absence of bubbles or other visible material in the PVC pipe wall. Is it colorless and transparent? High-quality Pvc steel wire hoses wall crystal clear? No impurities. And defective Pvc steel wire hoses color yellowing may be in the production process due to improper handling of decomposition, aging or long-term improper storage due.
