Suction hoses are used in mining, engineering construction, etc. to transport water and general neutral liquids. On the one hand, it can have good flexibility, on the other hand, it can also have high pressure resistance and wear resistance. The suction rubber hose is installed between the dredger and the pump. The inner diameter is generally between 100mm to 1300mm. The large-diameter suction hose is convenient to connect with the pipeline, to reduce the vibration caused by waves and ensuring the pipeline to a certain extent. Smooth flow within.
Discharge hoses are mainly used in the offshore dredging industry and are mostly used with dredgers to transport sand and slurry, water, oil, air, etc. in dredging operations. Generally, suitable working conditions are between -20° and 50°. The maximum inner diameter is 1300mm. Drainage hoses can be equipped with fixed steel flanges, bulk steel flanges, or rubber flanges.
The inner lining is composed of natural rubber and synthetic rubber, with good wear resistance, and the reinforcement layer is composed of high-strength rubber impregnated with chemical fibers and is reinforced by spiral metal wires. The cover is composed of synthetic rubber wrapped in oil, abrasion resistance, and weather resistance.
The flared hose provided by Hansel marine is suitable for sand mining operations with a water depth of more than 30 meters and a tower height of more than 30 meters. It has a large curvature, good performance, high rubber wear resistance, and a relatively long service life. One of the rubber hoses used in ore mining is economical and affordable. The flared hose has the same size as the steel flanged suction pipe and straight suction tube, but the wall thickness has increased by 25-30%. The intensity has also increased by 20%. The working pressure of the flared tube is -0.08~2.5Mpa.
