Rubber hose, as a critical component in industrial production, is widely used in various industries, including the petroleum, chemical, and food industries. Its primary function is to serve as a channel for transporting media. Therefore, the materials and designs of rubber hoses vary depending on the specific requirements of each industry. This article will detail the differences in the application of rubber hoses in the petroleum, chemical, and food industries.

 

Rubber Hose Applications in the Petroleum Industry

 

As a resource-intensive industry, the petroleum industry has a huge demand for rubber hoses and stringent requirements. Rubber hoses in the petroleum industry are primarily used to transport petroleum raw materials and their derivatives, such as crude oil, gasoline, diesel, and lubricants. Therefore, when selecting rubber hoses, their oil resistance, high temperature resistance, and high pressure resistance are key considerations.

 

Primarily, oil resistance is essential. When rubber hoses come into contact with petroleum and its products, their materials must be resistant to corrosion or dissolution by the chemical components in the petroleum. Tubing is typically made of materials such as fluororubber and nitrile rubber, which offer high oil resistance and long-term durability.

 

Secondly, the production environment in the oil industry is often characterized by high temperatures and high pressures. Rubber hoses must be able to withstand high temperatures without softening or melting, and withstand high-pressure fluids without bursting. Nitrile rubber, due to its excellent high-pressure resistance, and fluororubber, due to its high-temperature resistance, are the preferred materials for rubber hoses in the oil industry.

 

Furthermore, the oil industry has extremely high safety requirements, so rubber hoses must also possess anti-static and flame-retardant properties to prevent safety accidents.

 

Applications of Rubber Hoses in the Chemical Industry

 

The chemical industry uses rubber hoses in a wide variety of applications, involving a wide range of chemicals, resulting in relatively complex application requirements. This requires rubber hoses to possess both good chemical compatibility and excellent physical and mechanical properties.

 

Because the chemical industry involves numerous corrosive chemicals, rubber hoses must possess extremely high corrosion resistance. Materials such as perfluoroelastomer (FFKM) and chloroprene rubber can be used to create highly corrosion-resistant hoses, which are resistant to acids, bases, solvents, and various organic compounds.

 

Furthermore, rubber hoses in the chemical industry must also exhibit resistance to heat aging. Because long-term use in high-temperature and highly corrosive environments requires no significant degradation in hose performance, EPDM rubber holds a niche in this field due to its excellent heat-aging resistance.

 

Environmental protection and safety are always emphasized in chemical processes. Therefore, environmentally friendly rubber materials with little or no pollutants are widely used. Furthermore, the physical strength of the rubber hose, such as tensile strength and abrasion resistance, must also meet the requirements of the equipment and process.

 

Application of Rubber Hoses in the Food Industry

 

The food industry also places high demands on the material selection of rubber hoses. In addition to meeting relevant national standards, they are often also required to meet the company's own high standards. Food-grade rubber hoses are primarily used for transporting fluids such as milk, juice, beverages, and other food additives during production.

 

The primary requirement for rubber hoses in the food industry is safety, meaning they must be non-toxic, non-toxic, tasteless, and odorless. Therefore, food-grade rubber hoses made of silicone and EPDM are preferred, as they ensure they will not contaminate the food being transported.

 

Heat resistance is also crucial, not only because it needs to withstand high-temperature sterilization processes but also because rubber hoses may be exposed to hot fluids or environments for extended periods. Silicone is widely used due to its excellent temperature resistance (typically exceeding 200°C).

 

Antibacterial and mildew-resistant properties are another key requirement for rubber hoses in the food industry. To prevent bacterial growth and cross-contamination, rubber hoses should have a smooth, easy-to-clean surface and be antibacterial. The "Food-Grade Rubber Control Standard" stipulates that materials must be tested and certified by relevant agencies to ensure they do not produce harmful substances.

 

Summary

 

In summary, the applications of rubber hoses in the petroleum, chemical, and food industries each have their own unique characteristics and corresponding specialized requirements. In the petroleum industry, oil resistance, high-temperature resistance, and safety are emphasized; in the chemical industry, chemical compatibility, corrosion resistance, and environmental friendliness are more important; and in the food industry, non-toxicity, heat resistance, and antibacterial properties are crucial. Selecting the appropriate rubber hose material and formulation based on the diverse needs of each industry is key to ensuring a smooth production process and consistent product quality.

 

Continuously optimizing rubber hose design and improving its materials to provide safer and more effective protection for industrial production is the result of scientific and technological progress and market demand. In the future, as technology continues to advance, the application areas of rubber hose will become more extensive, and its performance will surely be even better, meeting the needs of emerging industries and markets.
