 High wear-resisting sand blast (guniting) rubber hose 

1. Technical support:

The product is developed through joint effort made by the technology department and national research center for rubber hose and cloth, and unique formula and advanced technologies are adopted.

2. Product characteristics:

Inner rubber layer: polyurethane and butyl rubber are adopted as the main materials, and special reinforcing agents are added. The finished inner rubber layer is in a yellow and transparent state, with characteristics such as high wear resistance, high tenacity and high pressure resistance. With a wear resistance index of 2-3 times higher than the ordinary sand blast rubber hose, it has gained a reputation as “the king of wear resistance” in the same industries.

Enhancement layer

The wrapped sand blast rubber hose adopts the high-quality tape as the enhancement layer, with good flexibility and strong pressure-bearing capacity.

The steel wire-braided sand blast rubber hose adopts the steel wire dedicated for copper plated rubber hose, characterized by a pressure-bearing capacity of 3-4 times stronger than the wrapped hose, high pressure endurance and good flexing resistance.

3. Range of application:

The product is mainly used in all kinds of tunneling works, mine workings, tunnel chambers and slope protection spraying. It also has a wide range of application in hydropower industry, mining industry, defense industry and sand blasting industry, etc.

4. Quality commitment:

It is suggested that a comparison in superiorities with products by other manufacturers should be made while using the product. Payments for those with poorer performance than the ordinary sand blast rubber hose shall be returned in full amount.
