Multi-field application of rubber pipe: Differentiated analysis of petroleum, chemical and food industries
As an important component in industrial production, rubber pipes are widely used in many industries such as petroleum, chemical industry, and food. Its main function is to serve as a channel for medium transportation, so the material and design of rubber pipes vary according to the characteristics and needs of different industries. This article will analyze in detail the differences in rubber pipes in petroleum, chemical industry and food industries.
Application of rubber pipes in the oil industry
As a resource-intensive industry, the oil industry has a huge demand for rubber pipes and strict requirements. Rubber pipes in the petroleum industry are mainly used to transport petroleum raw materials and their derivatives, such as crude oil, gasoline, diesel, lubricating oil, etc. Therefore, when choosing rubber pipes, they mainly consider their oil resistance, high temperature resistance and high pressure resistance.
First of all, oil resistance is an essential property. When rubber tubes come into contact with petroleum and its products, it is necessary to ensure that their materials will not be corroded or dissolved by chemical components in petroleum. Tubes usually made of fluoro-rubber, nitrile rubber and other materials have high oil resistance and can be used for a long time without deterioration.
Secondly, the production environment of the oil industry is often accompanied by high temperatures and high pressures. Rubber tubes must be able to withstand high temperatures without softening or melting, and can withstand high pressure fluids without bursting. Nitrile rubber has good high pressure resistance and high temperature resistance of fluoroelastomer, making them the preferred material of rubber pipes in the petroleum industry.
In addition, the oil industry has extremely high requirements for safety, so rubber pipes must also have anti-static and flame retardant properties to avoid safety accidents.
Application of rubber pipes in the chemical industry
There are many scenarios for using rubber pipes in the chemical industry, and there are many types of chemicals involved, so their application requirements are relatively complex. This requires that the rubber tube must have both good chemical compatibility and excellent physical and mechanical properties.
Since the chemical industry involves many corrosive chemicals, rubber tubes must have extremely high corrosion resistance. Materials such as perfluoroether rubber (FFKM) and neoprene can be made into high corrosion resistance tubes, which can resist the corrosion of acids, alkalis, solvents and various organic compounds.
At the same time, rubber pipes in the chemical industry must also have thermal aging resistance. Because the performance of the pipe should not be significantly reduced in long-term use under high temperature and high corrosion environments. EPDM rubber occupies a place in this field for its excellent heat-resistant aging properties.
Environmental protection and safety have always been emphasized during the chemical process. Therefore, environmentally friendly rubber materials that contain less or no contaminants are also widely used. Moreover, the physical strength of rubber pipes, such as tensile strength, wear resistance, etc., must also meet the equipment process requirements.
Application of rubber tubes in the food industry
The food industry also has high requirements for the selection of rubber pipes. In addition to meeting relevant national standards, it is usually necessary to meet the high standards of the enterprise. Food-grade rubber tubes are mainly used for the transportation of fluid substances during the production process, such as milk, juice, beverages and other food additives.
The primary requirement of rubber pipes in the food industry is safety, that is, non-toxic and harmless, odorless. Therefore, food-grade rubber tubes made of silicone materials and EPDM are preferred because they ensure that they do not contaminate the transmitted food.
In addition, heat resistance is also important, not only because of the process of resisting high temperature sterilization, but also because the rubber tube may be in hot fluid or environment for a long time. Silicone is widely used for its excellent temperature resistance (usually up to 200 degrees or above).
Antibacterial and mildew-resistant properties are another important requirement of rubber tubes in the food industry. To prevent bacterial growth and cross-contamination, the rubber tube has smooth surface, easy to clean and has antibacterial properties. The "Food Grade Rubber Control Standard" stipulates that materials must pass the inspection and certification of relevant institutions to ensure that no harmful substances are produced.
summary
To sum up, the application of rubber pipes in the petroleum, chemical and food industries has their own characteristics and corresponding professional requirements. In the petroleum industry, it emphasizes oil resistance, high temperature resistance and safety; in the chemical industry, it pays more attention to chemical compatibility, corrosion resistance and environmental protection; in the food industry, non-toxic and harmless, heat resistance, and antibacterial properties are the key. Selecting the right rubber pipe material and formula according to different needs of different industries is the key to ensuring smooth production process and stable product quality.
Continuously optimizing the design and material improvement of rubber pipes to provide safer and more effective guarantees for industrial production, which is the result of continuous promotion of scientific and technological progress and market demand. In the future, with the continuous development of technology, the application fields of rubber pipes will be more extensive, and their performance will be better, meeting the needs of emerging industries and markets.
