The thermal stability of rotary joint materials in high or low temperature environments varies depending on the type of material. The following is an analysis of the thermal stability of several common rotary joint materials in high or low temperature environments:
Stainless steel rotary joints have good corrosion resistance and high temperature performance, and are suitable for harsh working environments such as marine, chemical and other fields. In high temperature environments, stainless steel can maintain good mechanical properties and chemical stability, and is less prone to deformation or failure. Meanwhile, its surface is smooth, easy to clean, and has a long service life. In low-temperature environments, stainless steel also exhibits good stability and can resist potential issues such as condensation, freezing, or material embrittlement that may occur at low temperatures.
Copper rotary joints have good conductivity and are suitable for fields such as electrical equipment. In addition, copper material has high stability at high temperatures and is not easily oxidized or corroded. However, copper is relatively expensive and is often used in high demand situations. In low-temperature environments, the thermal conductivity of copper decreases, but the overall stability is still good, which can meet the low-temperature application needs within a certain range.
Aluminum alloy rotary joints have good thermal conductivity and wear resistance, making them suitable for applications that require heat dissipation or high strength requirements, such as mechanical equipment and other fields. In high-temperature environments, the thermal conductivity of aluminum alloys helps with heat dissipation, but excessively high temperatures may lead to a decrease in their mechanical properties. Therefore, the application of aluminum alloy rotary joints in high-temperature environments needs to be carefully considered. In low-temperature environments, the toughness of aluminum alloys may decrease, but overall stability is still acceptable, making it suitable for some low-temperature but not overly demanding application scenarios.
Polyurethane rotary joints have good elasticity and wear resistance, and are suitable for industries such as food and medical. In high temperature environments, polyurethane may soften or decompose, leading to a decrease in mechanical properties. Therefore, the application of polyurethane rotary joints is limited in high-temperature environments. In low-temperature environments, polyurethane still has good elasticity and can maintain a certain degree of sealing performance.
Polytetrafluoroethylene rotary joints have good corrosion resistance and high temperature resistance, and are widely used in high demand fields such as chemical, pharmaceutical, aerospace, etc. Under high temperature conditions, polytetrafluoroethylene can maintain stable chemical and mechanical properties, and is not prone to deformation or failure. At the same time, its surface is smooth, does not adhere to foreign objects, and is easy to clean and maintain. At low temperatures, polytetrafluoroethylene also exhibits good stability and can resist possible brittleness and other issues that may occur at low temperatures.
Polypropylene rotary joints have good toughness and corrosion resistance, and are suitable for industries such as food, medical, and pharmaceutical. Under high temperature conditions, polypropylene may soften or deform, leading to a decrease in mechanical properties. Therefore, the application of polypropylene rotary joints is limited in high-temperature environments. At low temperatures, the toughness of polypropylene is still good, but it is important to avoid brittleness caused by excessively low temperatures.
In summary, the thermal stability of rotary joints made of different materials varies in high or low temperature environments. When selecting materials for rotary joints, appropriate materials should be chosen according to specific application scenarios and requirements to ensure the performance and service life of the rotary joint. At the same time, it is also necessary to pay attention to regular maintenance and upkeep of the rotary joints to extend their service life and improve the overall reliability of the equipment.
