In order to satisfy the diversity of working conditions of the centrifuge, the materials constituting the centrifuge must be extensive, and different process conditions use different materials. The materials used in Zhangjiagang Baihun Centrifuge include carbon, alloy steel and cast iron, as well as non-ferrous metals and their alloys as well as non-metallic materials.
Centrifuges use a variety of non-ferrous metals and alloys of various types, commonly used aluminum, copper, lead, titanium and their alloys. In petrochemical industry, due to the requirements of special process conditions such as corrosion, low temperature, high temperature and high pressure, non-ferrous metals have many advantages, such as good conductivity and low temperature toughness of copper, relative density of aluminum, and radiation resistance and resistance of lead. Dilute sulfuric acid and other media corrosion. . However, since these non-ferrous metals are still rare metals and they are expensive, they can only be used as a whole in the low-pressure field. If they are high pressure, they are often used as lining materials.
Non-metallic materials have excellent corrosion resistance, rich source of raw materials, variety of species, suitable for local conditions, on-site materials, is a device with a wide range of development prospects. Non-metallic materials can be used as separate structural materials, as well as protective linings and coatings for metal equipment, as well as sealing materials, insulation materials and refractory materials for equipment. According to its composition is divided into inorganic non-metallic materials plant, organic non-metallic materials in two categories. It is a very important problem for chemical equipment to correctly select materials and adopt effective anti-corrosion measures for key equipment so that it will not corrode or reduce corrosion so as to ensure the normal operation of the equipment and prolong its service life.
In order to meet the production and operation requirements of centrifuges, related companies must not only consider the equipment structure, manufacturing process, service conditions, and service life, but also must adapt the material's corrosion resistance and physical and mechanical properties to the working conditions of the equipment. With less materials, abundant sources, and low prices, etc.
With the continuous development of industry and science and technology, higher requirements are placed on materials for manufacturing equipment and parts. In the design and manufacture of centrifuges, proper selection and proper use of materials is a very important task.
