How to identify the pros and cons of PVC steel wire pipe

In most cases, without any testing tools and testing conditions, we can roughly identify the quality of PVC steel wire pipes based on the senses of sight, smell and touch.

1. Observe whether the lumen is regular and whether the wall thickness is uniform. The inner cavity and outer edge of the high-quality PVC steel wire pipe are standard circular, and the annular pipe wall is evenly distributed. Take a PVC steel wire pipe with an inner diameter of 89mm and a wall thickness of 7mm as an example. The thickest part of the poor quality pipe can reach 7.5mm at the thickest part and only 5.5mm at the thinnest part. Working under high pressure, it is easy to cause the PVC steel wire pipe to burst or deform due to uneven force on the pipe wall, which affects normal use.
2. Observe whether there are bubbles or other visible objects on the wall of the PVC steel wire pipe, and whether it is colorless and transparent. The wall of the high-quality PVC steel wire pipe is crystal clear? No impurities. The yellowish color of the defective PVC steel wire pipe may be caused by decomposition, aging, or long-term improper storage during the production process due to improper handling.
3. The high-quality PVC steel wire pipe has no smell of other petrochemical products except a little plastic smell. The inferior steel wire pipe has an unpleasant pungent diesel smell, especially in the hot summer, people can't get close.
4. The inner and outer walls of high-quality PVC steel wire pipes are smooth and feel good, while low-quality pipes are rough.
