Flange large-diameter hoses are widely used in coal mine transportation. The following is a detailed exploration of their application:

1. Structure and characteristics of flange large-diameter hoses
Structure: Flange large-diameter hoses are mainly composed of inner rubber layer, steel wire layer and outer rubber layer. The inner rubber layer is responsible for contacting and conveying the medium, the steel wire layer provides strength and pressure resistance, and the outer rubber layer plays a protective role.
Features:
It has excellent corrosion resistance and can withstand the erosion of various chemicals and liquids.
It has high pressure resistance and can withstand high pressure without breaking.
It has good flexibility and toughness and can adapt to various complex use environments.
It has strong high temperature resistance and can work normally in high temperature environment.
It has outstanding wear resistance and can effectively resist the wear of particles.
2. Application of flange large-diameter hoses in coal mine transportation
Coal slurry transportation: In coal mines, the transportation of coal slurry is an important link. With its large diameter and wear resistance, flange large-diameter hoses can effectively reduce the wear of coal slurry flow on the inner wall of the pipeline and ensure the stable transportation of coal slurry.
Drainage system: The underground drainage system of coal mines also requires efficient and stable pipes. Flange large-diameter hoses can withstand high water pressure, reduce vibration and noise during transportation, and improve the comfort of workers’ working environment. At the same time, its excellent corrosion resistance also ensures the reliability of long-term use.
Other applications: In addition to the transportation of coal slurry and water, flange large-diameter hoses can also be used to transport other media, such as oil and gas. Flange large-diameter hoses also play an important role in coal mine ventilation, dust removal and other systems.
3. Connection method of flange large-diameter hoses
The connection method of flange large-diameter hoses generally adopts flange connection. This connection method makes installation and disassembly more convenient, and also improves the airtightness of the pipeline system to avoid leakage problems. The design of the flange joint adopts high-strength alloy material, which can withstand harsh use conditions under high pressure and high temperature environment.

4. Maintenance and maintenance of flange large-diameter hoses
In order to ensure the long-term and stable operation of flange large-diameter hoses in coal mine transportation, regular maintenance and maintenance are required. This includes checking the wear of the pipeline, cleaning the inner wall of the pipeline, replacing damaged parts, etc. At the same time, it is also necessary to avoid the pipeline being affected by adverse factors such as excessive pressure and temperature.

In summary, flange large-diameter hose has a wide range of application prospects in coal mine transportation. Its excellent performance characteristics, reliable connection methods and convenient maintenance and care measures make it an ideal choice in coal mine transportation systems.
