Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it sits flush against the mounting surface. 2. Thread the accompanying nuts onto the U-bolt legs, hand-tightening initially. 3. Use appropriate wrenches to tighten the nuts evenly, achieving a secure fit without over-compression of the pipe or mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe's nominal diameter.Always verify the inside dimensions (width and length) of the U-bolt against the actual pipe OD and required clearance for the intended application.
Over-tightening the nuts, potentially damaging the pipe or mounting surface.Tighten nuts incrementally and evenly. A torque wrench can be used for precise tensioning if specified by application requirements.

Common Applications

  • Marine hardware and shipbuilding
  • Chemical processing plant piping
  • Food and beverage industry plumbing
  • Exhaust system supports
  • General pipe and conduit securing

⚠️ Engineering Warnings

  • Ensure threads are clean and free of debris before installation to prevent galling or cross-threading.
  • Always use appropriate personal protective equipment (PPE) during installation.
