Rotating Pipe Joint

Material selection and precautions of rotary joint

The material of the rotary joint is generally considered according to the nature of the medium, the use environment and the working pressure.

Common rotary joint materials include the following:

1. Carbon steel: suitable for general low temperature, low pressure media, such as tap water, industrial wastewater, etc.

2. Stainless steel: has excellent corrosion resistance, suitable for high temperature resistance, high pressure, corrosive media occasions, such as chemical, petroleum, pharmaceutical and other industries.

3. Cast iron: suitable for low temperature, low pressure general media, can also be used to transport corrosive gases and liquids.

4. Copper: suitable for conveying cooling water, air conditioning water and other liquid media.

5. Aluminum alloy: used in occasions with high lightweight requirements, such as some aviation and aerospace fields.

Note of rotary joint:

1. Material selection should be based on the nature of the medium and the use environment, and the requirements should meet national standards and industrial standards.

2. Rotary joints of different materials have different degrees of corrosion, wear and other problems during use, and need regular inspection and maintenance.

3. The rotary joint should be inspected before use, including whether there is obvious damage to the appearance and whether there is any problem in the sealing performance.

4. When connecting the rotary joint, it should be operated in accordance with the requirements of the specification, and it is forbidden to process or change it without authorization to avoid safety accidents.

5. According to different media and environment, different sealing structures are used to ensure the normal operation and service life of the joint.

Rotary joint is an important pipe connection element widely used in industrial production and civil fields. The selection of suitable material plays a crucial role in its performance and life. Regular inspection and maintenance should also be paid attention to during use to ensure that it works safely and reliably.
