Product Description
1. CONSTRUCTIONS: This hose consists of an inner tube of oil-resistant synthetic rubber, one or multilayer spiral fabric reinforcements, or steel wire sprial bear negative pressure, and an oil and weather resistant synthetic rubber cover.
2. CHARACTERISTIC: This hose have almost no tolerance, and they are capable of resistance to oil and water, light and abrasion well. The minimum explosive pressure is fourfold to work pressure.
3. APPLICATIONS: All kinds of steel wire (or suck) hose are made in suitable materials due to different purpose. Their advantages are logical design, excellent quality, durable. They are used to send or suck ( negative pressure ) many kinds of liquid power solid etc.
4. PERFORMANCE
1. Rubber hose pipes are used with dredgers for silt/gravels conveyance.
2. Pipe wall thickness range: From 20mm up to 50mm.
3. The suitable working temperature: From -20° C to +50° C.
4. Abrasion-resistant and bending -resistant.
5. It is convenient to install, flexible to use and safe.
