In the steel wire pipe industry, commonly known as PVC steel wire reinforced hose, spring pipe, steel wire wrapped transparent pipe, etc., the demand for steel wire pipes is increasing day by day to meet the operational needs of various industries. Subsequently, many steel wire pipe manufacturers were born, producing a wide variety of PVC transparent steel wire pipes with varying internal qualities. So, how to choose high-quality steel wire pipes and how to distinguish them?

In order to help customers avoid unnecessary economic losses in their choices, how to judge the quality of steel wire pipes and how to choose high-quality steel wire pipes?

1、 If conditions permit, professional instruments can be used to test the thermal deformation temperature or Vicat softening point, chromaticity, turbidity, resistance to positive and negative pressure, burst pressure, halogen and nitrate content, and tensile strength of PVC steel wire pipes.

2、 In the absence of technical conditions, visual, olfactory, tactile, and other factors can be used to determine the quality of PVC transparent steel wire pipes.

1. Observe whether the wall thickness of the steel wire pipe is uniform. If the manufacturer allows, samples can be taken from the middle, which is more direct. This is mainly to prevent illegal elements from falsifying during the production process. Uneven thickness of the pipe wall can lead to easy breakage and explosion during use, seriously shortening the service life of the steel wire pipe.

2. High quality steel wire pipes should be transparent and odorless, with particles processed through special techniques that are crystal clear and free of any impurities; On the contrary, low-quality pvc hose particles doped with impurities will appear yellowing, aging resistance and other characteristics.

3. Observe whether there are bubbles, paste, etc. on the pipe wall under good lighting conditions.

4. High quality steel wire pipes have a very low odor, except for a faint plastic smell, without any irritating odors like petroleum additives. On the contrary, low-quality steel wire pipes have a pungent odor and are made by adding a large amount of recycled materials and chemical raw materials, especially in high temperature seasons, making them impossible to approach.

5. Take a section of steel wire from the cut surface of the steel wire pipe for experimentation to see if it is easy to break. High quality steel wire requires professional tools for cutting, and in addition to ensuring its flexibility, it is also necessary to increase its tensile strength.

6. High quality steel wire pipes have smooth inner and outer walls, and evenly wound steel wires. Conversely, low-quality steel wire pipes have rough hand feel and low transparency.
