How to easily identify PVCSteel wire pipeIn most cases, without any testing tools and testing conditions, we can make a rough identification of PVC steel wire pipe according to the feeling, smell, touch, etc.
1. Observe whether the lumen of the steel wire tube is neat and whether the wall thickness is uniform. Excellent PVC steel wire pipe, the inner cavity and the outer edge are standard circular annular pipe wall. PVC steel wire pipe with an inner diameter of 89mm and a wall thickness of 7mm is taken as an example. The thicker part of the pipe wall with poor quality is only 7.5mm. Working under high pressure is easy to cause uneven stress on the pipe wall, causing PVC steel wire pipe to burst or deform, affecting normal use.
2. Observe whether there are bubbles or other visible substances on the wall of the PVC steel wire pipe to determine its colorless and transparent. Good PVC wire pipe has a crystal wall, without any impurities. The color of the inferior PVC steel wire pipe is yellowed, which may be caused by partial decomposition, aging or long storage time caused by improper handling during the production process.
3, high quality PVC steel wire pipe, in addition to a small amount of plastic smell, there is no smell of any other petrochemical products. And inferior steel wire pipe has a pungent smell of diesel, especially in the hot summer people are more difficult to approach.
4. The inner and outer walls of high-quality PVC steel wire pipes are smooth, and low-quality pipes with good hand feeling are relatively rough.
5. When measuring the wall thickness, cut off both ends of the PVC steel wire pipe, and select the middle pipe as the sample to prevent some manufacturers from making an article at both ends of the pipe. The actual wall thickness is at both ends of the pipe.
6. Intercept a few centimeters of heavy folded steel wire at both ends of the PVC steel wire pipe to check the strength and toughness of the steel wire. The steel wire with poor quality will be folded once or twice, while the high quality PVC steel wire pipe steel wire needs special tools to cut off. The quality of the wire determines the quality problem caused by the wire. PVC wire is prone to irreversible deformation.
The above is for you to introduce how simple identification of PVCSteel wire pipeThe quality of the content, I hope to help you!
