Dredger Pipeline

Self-floating hoses are generally suitable for the harshest marine and mining environments. Used with PE foam, and it is generally used with dredgers to transport mud, clay, fine sand, fine-medium sand, etc. Working conditions are -20°C to 50°C, in general, the self-floating hose is efficient and economical.

Tapered floating hose is mainly divided into A hose and B hose. A hose refers to a device with buoyancy at one end and no buoyancy at the other end. The quick coupling is connected to the buoyancy end, and the non-buoyancy end at the other end is connected to the B hose. And the B hose is directly connected with the normal floating hose, and the A hose can replace the dredge ball joint to form a tapered floating pipeline.

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.

The rubber expansion joints provided by Hansel marine are mainly used in pipeline systems to absorb pipeline motion, reduce stress, reduce system vibration and noise, compensate for misalignment/offset, and minimize the impact of starting surge on rotating machinery .

PE floats are generally used in conjunction with HDPE pipes, steel pipes, and Rubber hoses, mainly to let the pipeline work on the water. It has high floating ability. The main material is high density polyethylene plastic (MDPE/HDPE), which has great buoyancy. The thickness is generally 5-66mm. On the other hand, PE floats can also be filled with sand etc. instead of sinking stone. PE flotation machine has reasonable structure and good performance, which is the best choice for traditional steel flotation machine.
