discharge rubber hose
1)Specifications:
Highly resistant against weathering, UV lights and Ozone
Hose and fittings are available in a wide variety
2)Introduction:
1.Dredging rubber hose is designed for offshore dredging application. It can be connected with pipeline well, and reduce sway for wave, so that conveying medium can flow more smoothly. Our dredging rubber hose are purpose built to the special requirement of our clients.
2.We are in the position to build hoses sizes ranging from 100 mm ID to 2200 mm ID. Our designers will select the most appropriate materials from a wide range of products available to us to meet service and demands requested by our clients, i.e. in regard to wear resistance, pressure ratings, tensile strength, bending capabilities and so on.
3)Advantage:
Highly resistant against weathering, UV lights and Ozone
Hose and fittings are available in a wide variety which is selected on duty requirements
