There are various materials for rotary joints, and the selection of these materials depends on the working environment, medium characteristics, pressure, temperature, as well as the required wear resistance, corrosion resistance, and other factors of the rotary joint. Here are some common rotary joint materials and their characteristics:
1).stainless steel:
· Features: Has good corrosion resistance and high temperature performance, smooth surface, easy to clean.
· Application: Suitable for harsh working environments such as marine, chemical, and other fields.
2).Copper and copper alloys:
· Characteristics: Copper rotary joints have good conductivity, while copper alloys (such as those containing elements such as tungsten, iron, and silicon) can increase strength and wear resistance. In addition, copper material has high stability at high temperatures.
· Application: Suitable for electrical equipment and some high demand occasions.
3).aluminium alloy:
· Characteristics: It has good thermal conductivity and wear resistance.
· Application: Suitable for occasions that require heat dissipation or high strength requirements, such as mechanical equipment and other fields.
4).Cast iron, gray iron, ductile iron:
· Characteristics: These materials have high strength and wear resistance.
· Application: Commonly used for the housing or support structure of rotary joints.
5).45 # Steel:
· Characteristics: It has high strength and toughness.
· Application: Used in rotating joints with specific requirements.
1).Polyurethane:
· Characteristics: It has good elasticity and wear resistance, as well as a certain degree of corrosion resistance.
· Application: Suitable for industries such as food and healthcare, it can resist the erosion of various chemicals and solvents.
2).Polytetrafluoroethylene (PTFE):
· Features: Excellent corrosion resistance and high temperature resistance, smooth surface, no foreign matter adhesion, easy to clean and maintain.
· Application: Widely used in high demand fields such as chemical, pharmaceutical, aerospace, etc.
3).Polypropylene (PP):
· Characteristics: It has good toughness and corrosion resistance, is non-toxic, odorless, non deformable, and has high safety.
· Application: Suitable for industries such as food, healthcare, and pharmaceuticals.
The spring in the rotary joint is usually used to provide sealing pressure, and its material selection is also crucial. Common spring materials include:
· Phosphorus bronze: suitable for media such as oil and seawater.
· Copper plated carbon steel: suitable for ambient temperature environment.
· Chromium steel: used in weakly corrosive media.
In addition to the main materials mentioned above, rotary joints may also use other auxiliary materials such as O-rings, gaskets, etc. The selection of these materials also needs to be determined based on the specific working environment and medium characteristics.
In summary, the selection of materials for rotary joints is a comprehensive process that needs to be determined based on specific application scenarios and requirements. When selecting materials, factors such as material performance, cost, and maintainability should be fully considered.
