Basic structure and classification of high-pressure hoses

 

In the mining and industrial sectors, especially in extreme environments, there are strict and special requirements for pipelines transporting materials and liquids. As a core transportation tool, high-pressure hoses not only need to withstand high pressure, but also need to adapt to changing working environments and face erosion from different substances such as water, oil, acid and alkali. This article will deeply explore the diversity, durability and application of mining high-pressure hoses in water delivery, water absorption and filtration of emulsions, and provide a comprehensive purchase and use guide for related industries.

 

 1. Basic structure and classification of high-pressure hoses

 

High-pressure hoses generally consist of three parts: inner rubber layer, reinforcement layer and outer rubber layer. The inner rubber layer is in direct contact with the conveying medium and has good oil resistance or water resistance; the reinforcement layer is usually woven from high-strength steel wire, which is the key to the pipeline being able to withstand high pressure; the outer rubber layer needs to have certain weather resistance and wear resistance , protect the pipeline from the external environment. These hoses can be divided into various types according to the use environment and requirements, such as commonly used wear-resistant hoses, oil-resistant hoses, high-temperature resistant hoses, etc.

 

 2. The necessity of wear resistance

 

In mining, pipeline systems often need to pass through complex terrain, not only facing sharp rock wear, but also withstanding the impact of various gravels and dust. The wear resistance of high-pressure hoses has become the key to extending their service life. Wear-resistant hoses usually use high-strength materials as the outer layer. In some cases, the outer layer is even added with an additional protective layer or treated with special materials to adapt to more harsh working environments.

 

 3. Ability to resist grease and chemicals

 

Mining hoses often need to transport emulsions containing grease or other chemical liquids, and these media may cause corrosion to the material. Therefore, it is particularly important to choose a high-quality oil-resistant hose. The inner material of oil-resistant hose must be able to resist the attack of oil and grease and maintain the integrity of the material to avoid leaks and interruption of service.

 

 4. The particularity of steel wire reinforced hoses in mining

 

Steel wire reinforced high pressure hoses are widely used in various machinery and equipment in the mining industry. The addition of steel wire can significantly enhance the pressure-bearing capacity of the pipeline, allowing it to operate safely in extremely high-pressure environments. In addition, this reinforcement method also increases the tensile resistance of the pipeline and reduces deformation problems caused by mechanical forces during long-distance transmission.

 

 5. Temperature adaptability analysis

 

The temperature in mining areas changes greatly, and high-pressure hoses must adapt to complex environments of low and high temperatures. High temperatures will soften the hose material, reducing its pressure-bearing capacity; low temperatures may cause the material to harden, increasing the risk of brittleness. Therefore, choosing the right materials and structural design, and adjusting the hose formula according to the specific environment, are the keys to ensuring that it maintains good performance at different temperatures.

 

 6. Application examples and operation suggestions

 

In actual mining operations, correct installation and regular maintenance of high-pressure hoses are necessary to ensure their long-term operation. During installation, it is necessary to ensure that the pipes are not twisted and the connections are tight; during use, the wear degree of the pipes and the sealing of each connection part should be checked regularly. In addition, for hoses that convey special chemicals or operate under extreme temperatures, products that meet specific standards should be selected to ensure safety and efficiency.

 

 Conclusion

 

Mining is an industry with extremely strict equipment requirements, and high-pressure hoses play an indispensable role in it. The selection and use of appropriate high-pressure hoses is not only related to production efficiency, but also directly affects the safety of operations. Therefore, understanding the material properties, structural design and application details of high-pressure hoses in actual operations is an important step for mine managers and engineers to improve work efficiency and safety.
