The inner cavity and outer edge of the high-quality clear PVC wire reinforced flexible hose are standard circular, and the annular pipe wall is evenly distributed. When the poor quality hose works under high pressure, it is easy for the pipe wall to receive uneven force, causing the PVC steel wire hose to burst or deform, which affects normal use.
Check whether there are bubbles or other visible objects on the wall of the PVC steel wire hose, and whether it is colorless and transparent. The wall of the high-quality PVC steel wire hose is crystal clear without any impurities.
The yellowish color of the defective PVC steel wire hose may be caused by decomposition, aging, or long-term improper storage during the production process due to improper handling. In addition, the inner and outer pipe walls of high-quality PVC steel wire hose are smooth and feel good, while low-quality pipes are rough.
Except for a little plastic odor, the high-quality PVC steel wire hose has no odor of other petrochemical products. The inferior steel wire pipe has an unpleasant pungent diesel smell, especially in the hot summer, and people can't get close.
When measuring wall thickness, both ends of the PVC steel wire pipe should be cut off, and the middle pipe should be selected as the sample test to prevent errors.
