PU steel wire hose, polyurethane steel wire hose is a flexible polyurethane hose with high wear resistance that can transport wood chips and similar waste materials. The surface of this hose is strengthened by a spiral steel wire spring, with superior pressure resistance, smooth inner surface of the tube, and high conveying efficiency. It can be used in the range of -40°C to +120°C. The hose is scratch-resistant, chemical-resistant, and anti-static, and is available in a variety of specifications. It has high abrasion protection and abrasion resistance 6 times higher than most rubber materials, and 5 times higher than soft PVC. The interior is smooth to optimize flow characteristics, extensibility, high tensile strength and tear strength. Good resistance to minerals, oils and chemicals, good resistance to ultraviolet rays and ozone, and low temperature expansion. The bending radius is small, it is not easy to kink, does not contain softener and halogen, and does not leak gas and liquid.

  PU steel wire hose is made of German imported raw materials with copper-plated steel wire, antibacterial and hydrolysis, good chemical resistance, extreme wear resistance, and the bottom copper-plated steel wire strengthens the strength of the tube, very high Shaft strength, very smooth material, the bending radius is approximately equal to the outer diameter, can discharge static electricity (according to BGR-132, formerly ZH 1/200) spiral wire grounding, widely used in industrial vacuuming, such as woodworking machinery vacuum pipes, furniture factories, etc. Used in abrasive solids such as dust, powder, fibers, chips and particles, gas and liquid environments, for dust removal and suction workshops, industrial vacuum cleaners, paper and textile fibers.
  The relationship between the wall thickness of the PU steel wire hose and the performance in various aspects:
   1. The thinner the wall thickness of the PU steel wire hose, the better its flexibility and bending performance. The 0.4mm PU steel wire hose has the most flexible expansion and contraction. It has the highest expansion frequency in the same time and is also the easiest to bend and roll. This kind of wall thickness hose is suitable for the expansion and contraction of the pipe and the ventilation of machinery with high requirements for bending performance. Vacuum.
  2, the thicker the wall thickness of the PU steel wire pipe, the better its wear resistance and corrosion resistance will be. The 0.9mm PU steel wire hose has the highest abrasion resistance rate due to the thickest wall thickness. Under the same abrasion conditions, it has the longest use time. At the same time, it has the best acid and alkali resistance and corrosion resistance. This thick-walled PU hose is suitable for working environments with high abrasion and high pH.
  3, 0.6mm PU steel wire pipe has a wall thickness between 0.4mm and 0.9mm, and its flexibility, wear resistance, and corrosion resistance are also in between. It is the most commonly used.
