How to identify the advantages and disadvantages of PVC steel pipe

Most customers ask how to identify the pros and cons of pvc steel pipes in plastic hoses without testing tools and testing conditions? To identify the advantages and disadvantages of plastic steel wire pipe.

1. look

To see is to use the naked eye to observe whether the wall thickness of the plastic pipe is uniform, and whether there are air bubbles or impurities on the pipe wall.

(1) The inner cavity and outer edge of the good quality pvc plastic steel wire pipe are in a standard circle, and the annular pipe wall is evenly distributed, and it is not easy to deform under normal pressure. Inferior plastic steel wire pipes have uneven wall thickness, and the inner cavity and outer edge are not in a standard circle, which is prone to deformation or burst under normal pressure, affecting normal use and service life.

(2) The wall of high-quality plastic steel wire pipe is colorless and transparent without any impurities; the color of inferior quality may be yellowed and there are impurities, which are caused by decomposition or aging caused by improper handling in the production process, or caused by improper long-term storage.

2. Smell

Smell the tube with your nose to see if it smells. Except for a little plastic odor, high-quality steel pipes do not have any other petrochemical odors; poor-quality steel pipes have an unpleasant diesel odor.

3. Touch

Touch the inner and outer walls of the steel tube with your hands to see how it feels. The high-quality feel is good, and the inner and outer tube walls are smooth; the inferior tube walls are rough.

4. Go to both ends

Remove both ends of the steel wire pipe and select the middle part as a sample test to prevent the manufacturer from making a fuss at both ends of the pipe, but in fact the wall thickness of the pipe is slightly thinner than the two ends of the pipe.
