Apply Proper Sealing: Apply the recommended sealing materials and techniques as specified by the manufacturer. This may involve using gaskets, O-rings, or sealants to ensure a tight and secure seal. Follow the manufacturer’s instructions regarding the application of sealing materials, torque specifications, and tightening sequences to prevent leaks.

Properly Tighten Fasteners: Use the recommended torque specifications and tightening sequences when fastening the rotary union to the equipment. Over-tightening or under-tightening can lead to issues such as leaks, distortion of sealing surfaces, or damage to the rotary union. Follow the manufacturer’s guidelines to achieve the correct level of tightness.

Conduct a Leakage Test: After the installation, perform a leakage test to ensure the integrity of the rotary union. Apply the appropriate pressure or flow rate to the system and inspect for any signs of leakage. If leakage is detected, double-check the sealing, connections, and fasteners to identify and address the source of the issue.

Document Installation Details: Keep a record of the installation details, including the date, installation technician, torque values, sealing materials used, and any other relevant information. This documentation will be valuable for future reference, maintenance, and troubleshooting purposes.

Regularly Inspect and Maintain: Once the rotary union is installed, establish a regular inspection and maintenance schedule. Periodically check the condition of seals, fasteners, and connections. Conduct routine cleaning, lubrication, and seal replacement as recommended by the manufacturer. Regular maintenance will help identify potential issues early and ensure the continued performance of the rotary union.

By following these best practices for rotary union installation, you can optimize the performance, reliability, and longevity of your system. Proper installation reduces the risk of leaks, misalignment, and premature wear, allowing for efficient fluid or gas transfer in your rotating applications.
