Mining hoses play an important role in industries such as coal mines, and their advantages and disadvantages can be summarized as follows:
Advantages:
1. High strength: Mining rubber hoses are made of high-strength materials, which have excellent mechanical strength, tensile and extrusion resistance, and can withstand large pressure and tension.
2. Wear resistance: In industries such as mining and oil fields, the working environment is harsh and the wear is severe. However, the service life of mining rubber hoses can be several times longer than ordinary pipelines, greatly reducing maintenance costs.
3. Corrosion resistance: Mining rubber hoses can resist the corrosion of chemicals such as acid, alkali, and oil, and can be used for a long time in harsh environments.
4. Pressure resistance and wear resistance: High pressure rubber hoses used in coal mines usually have high pressure resistance and wear resistance, and can withstand wear and tear in high-pressure liquid transportation and coal mining environments.
5. Corrosion and temperature resistance performance: High pressure rubber hoses used in coal mines usually have characteristics of corrosion resistance and high temperature resistance in response to corrosive substances and high temperature conditions that may exist in the coal mine environment.
6. Anti static: Some high-pressure rubber hoses used in coal mines have anti-static function, which helps to reduce the harm of static electricity to equipment and workers.
Disadvantages:
1. Relatively poor temperature resistance: Some mining rubber hoses may have poor temperature resistance and cannot withstand the action of high-temperature liquids.
2. Easy to age: After long-term use, mining rubber hoses may easily lose flexibility and elasticity, and need to be replaced regularly.
3. High installation cost: The installation of mining rubber hoses may require professional personnel, so the installation cost may be higher.
4. Safety hazards: In the working face and roadway, if a few hundred meters long, exposed high-pressure pipeline malfunctions, it may increase safety hazards, such as U-shaped card breakage or detachment, joint detachment, high-pressure hose explosion, etc., which may lead to dangerous situations.
