Overview of Dredging Rubber Hose

Dredging rubber hose used for mud piping of dredge to suck or discharge of mud, water, oil, air, and powered in Industry, agriculture, factory, mining and building etc.

Materials

Tube: Smooth NR/ synthetic rubber, generally color is black

Reinforcement: one or multi-layer spiral fabric reinforcements, steel wire spiral layer

Cover: Oil, abrasion and weather-resistant wrapped synthetic rubber

Structure

  1. The inner rubber liner is composed of wear-proof natural rubber and synthetic rubber
  2. The reinforcement layer is composed of high strength rubber dipped chemical fiber and reinforced by spiral metal wire.
  3. The rubber cover is composed of natural rubber and synthetic rubber.
  4. The surface of the hose takes the shape of corrugated

Advantage of ZHW dredging rubber hose:

  • Long lifespan, more than 50 years under normal condition.
  • Good corrosion resistance.
  • Good crack growth resistance.
  • Little coefficient of friction and low flow resistance.
  • Excellent wear resistance, its wear resistance is 4 times higher than steel pipes under normal conditions.
  • Good solder ability, its interface strength is higher than the pipe body.
  • Good flexibility and anti-scratch ability.
  • Very high impact resistance.
  • The unique resistance to low temperature, workable at temperature – 40-60℃.
  • Light weight, 1/8 weight of steel pipe, easy for transportation and installation.
  • Flexible metal flange for connection, easy for installation and disassembly.
