High wear-resistant sandblasted hose

High wear-resistant sandblasted hose

1. Product technical support:
This product is jointly developed by experts of the United Nations Hose and Tape Research Center of the company’s technical department, using unique formula and advanced technology.
2. Product Features:
Inner rubber: Polyurethane and butyl rubber are the main raw materials, and special reinforcing agent is added. The color of the finished rubber is yellow transparent, with high wear resistance, high toughness and high pressure resistance. The wear resistance index is 2-3 times that of ordinary sandblasting hose. In the same industry, enjoy the reputation of “wearing king”.
Reinforced layer The
cloth blasting hose is made of high-quality rubbing tape as the reinforcing layer, which has good flexibility and strong pressure bearing capacity. The
steel blasting hose is woven with special steel wire for copper-plated hose, and the working pressure is 3-4 times that of the cloth hose. High pressure resistance and superior flex resistance.
3. Scope of application: The
products are mainly used in various tunnel projects, wells, caverns, slope protection and anchoring, and have a wide range of applications in the fields of hydropower, mining and military defense.
4. Quality Commitment: It is
recommended to use this product in comparison with other manufacturers’ products for the first time to compare the superiority of our products. Less than the normal sandblasting hose performance, the full payment is refunded.
