Flange suction discharge rubber hose

Large diameter flange suction discharge rubber hose also known as Large diameter suction and discharge hose, dre dging hose, flange steel wire suction and discharge hose, sand suction and discharge hose.
The large diameter suction discharge rubber hose adopts weather-resistant and aging-resistant synthetic rubber, which can maintain good strength and resilience even after long-term wind and wave stress and ultraviolet radiation. Ensure long-term stable operation of the sludge discharge pipeline. The types of rubber hoses of dredgers are straight-through, flared, and embedded with steel flanges, which can be easily and quickly docked with rigid buoy discharge pipelines.
 
Flange suction discharge rubber hose construction:
large diameter inner rubber layer, steel wire reinforcement layer, outside rubber layer and flange ends.

1. Hose diameter: 102-1300mm
2. Connect type:floating and fixed flange
3. Operating pressure range: 0.4-3.0Mpa(depend on hose diameter)
4. Flange standard: GB, ANSI, JIS, ASME, GOST, DIN, BS, Table E etc
5. Working temperature: -40 -+120℃
6. Hose length can be customized according to your requirements.


Suction and discharge rubber hose features：

1. Excellent acid and alkali resistance, we know that the situation under the mine is more complicated, and the water quality sometimes has a larger acid and alkali condition. We use EPDM rubber for production, so that the pipe body has a certain acid and alkali resistance, special circumstances Can be mixed with acid and alkali resistant hoses.

2. The pressure resistance is strong, the length of the roadway is relatively long, and the pipeline is very long when carrying water. According to the principle of pressure, the longer the pipeline, the greater the pressure on the pipe wall. This requires the water delivery hose to withstand a lot of pressure. Under negative pressure, use a four-layer steel wire winding or an 8-layer cord + spiral steel wire skeleton structure to ensure that the pipe body will not be flattened and bonded The layer must also have sufficient anti-suction force to prevent the inner glue from degumming and blocking the pipeline.

3. The connection methods of the scution discharge hose include flange type, high-pressure union, hammer union, quick joint, etc., the connection of each section of pipe is required to achieve the purpose of fast non-leakage. the most common type is the flange connection. For the steel wire braided pipe, the crimp connection is used, while the spiral steel wire frame generally uses a more reliable vulcanized flange connection.

and other fluid transmission pipeline.
