mWe can roughly judge the quality of PVC Steel Wire Hose according to the sense of vision, smell, touch and so on.
Firstly,observe whether the lumen is regular and the thickness is uniform. The inner cavity and outer edge of high quality PVC Steel Wire Hose are presented in a standard circular shape, and the annular hose wall is evenly distributed.
Secondly, observe 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 and free of any impurities.
Thirdly, the high-quality PVC Steel Wire Hose has no smell of other petrochemical products except a little plastic smell. The inferior steel wire hose pipe has an unpleasant pungent diesel smell. Especially in the hot summer, people can’t get close to it.
Fourthly, the inner and outer hose walls of high-quality PVC Steel Wire Hose are smooth and feel good, while those of low-quality hoses are rough.
Fifthly, take the middle pipe for sample testing, not the sides when test the thickness. Besides, avoid a few illegal manufacturers to make a fuss at both ends of the hose. The actual thickness is thinner than the thickness at both ends of the hose.
