Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring the pipe is centrally located within the U-bolt's arc. 2. Insert the threaded legs of the U-bolt through the mounting surface or bracket, applying the provided flat washers and lock nuts. 3. Tighten the nuts evenly and progressively, alternating between nuts, to achieve a secure and snug fit without overtightening, which could deform the pipe or mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Always verify the nominal pipe size and compare it with the U-bolt's inside dimensions (Width A and Length B) to ensure a proper fit.
Overtightening nuts, causing damage to the pipe or mounting.Tighten nuts incrementally and evenly. Stop when the U-bolt is snug and the pipe is firmly secured, avoiding excessive force.
Not using washers, leading to uneven pressure distribution.Always use flat washers under the nuts to distribute the clamping force evenly across the mounting surface and prevent damage.

Common Applications

  • Pipe and conduit support in chemical plants
  • Marine and offshore structural applications
  • Food and beverage processing facilities
  • Water treatment and wastewater management systems

⚠️ Engineering Warnings

  • Ensure proper torque is applied to avoid damaging the pipe or mounting hardware.
  • For critical load-bearing applications, consult engineering specifications and load ratings.
