Globe Star Engineers presents information on troubleshooting major causes of rotary joint and rotary union problems. Improper piping can lead to strains that exert excessive force on components and cause misalignment. Rotary joint or union misalignment is also a major issue and can occur when components are not properly aligned, leading to increased wear. Lack of or improper torque restraints can increase radial forces on self-supporting joints. The document provides tips on preventing these issues such as proper installation, alignment, and use of an appropriately designed torque restraint.
