What are the performance characteristics of steel wire hose
1. If conditions permit, professional instruments can be used to test the thermal deformation temperature of pvc wire hose, color degree, turbidity, positive and negative pressure resistance, blasting pressure, halogen, nitrate content, and tensile strength, etc.
2. In the absence of technical conditions, vision, smell, touch can be used to distinguish the good and bad quality of pvc transparent steel wire hose.
（1）Observe whether the wall thickness of the steel wire hose is uniform. If the manufacturer allows sampling from the middle so more directly, mainly to prevent criminals from falsification in the production process. The uneven thickness of the hose wall will lead to easy fracture and blasting in the use process, and seriously shorten the service life of the steel wire hose.
（2）Good quality wire hose shall be transparent and tasteless. The particles processed by special process are crystal clear without any impurities; on the contrary, low quality wire hose particles are mixed with impurities, yellowing, not anti-aging and other characteristics.
（3）Observe whether there are bubbles and paste on the hose wall under good lighting conditions.
（4）The smell of high-quality steel wire hose is very small, except for the weak plastic smell, there is no pungent odor like petroleum additives, on the contrary, the low-quality steel wire hose smell is pungent, using a large number of recycled materials and chemical raw materials added, especially in the season of high temperature, simply can not be close to.
（5）Take a section of steel wire from the cut surface of the steel wire hose to do experiments to see whether it is easy to break. The good quality steel wire needs professional tools. In addition to ensuring the good quality steel wire hose and its flexibility, it also needs to increase its tensile strength.
（6） High quality steel wire hose, smooth inner and outer walls, steel wire winding evenly, while the low quality steel wire hose has rough feel and low transparency, etc.
