Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it is centered for even pressure distribution. 2. Thread the provided nuts onto each leg of the U-bolt, hand-tightening initially. 3. Using appropriate wrenches, tighten the nuts evenly and progressively until the pipe is firmly secured, avoiding over-tightening which can deform the pipe or bolt.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the pipe diameter.Always verify the nominal pipe size and select a U-bolt with the corresponding inside dimensions (width and length) for a secure and proper fit.
Over-tightening the nuts, causing damage to the pipe or bolt.Tighten nuts gradually and evenly. Consult torque specifications if critical, but generally, tighten until firm and secure without deforming the components.

Common Applications

  • Pipe support and clamping in marine environments
  • Conduit and cable tray mounting in corrosive atmospheres
  • Structural fastening for lightweight pipe systems

⚠️ Engineering Warnings

  • Ensure compatibility of the U-bolt material with the surrounding environment to prevent galvanic corrosion.
  • Do not exceed the recommended load capacity for this U-bolt; consult engineering specifications for specific applications.
