Installation Procedure

1. Select appropriate mounting surface and hardware (nuts and washers) compatible with the 1/2"-13 thread. 2. Position the U-bolt around the 3" nominal pipe, ensuring it rests securely in the pipe's contour. 3. Pass the threaded legs through the mounting holes, and secure with nuts and washers, tightening evenly on both sides to achieve firm but not over-stressed clamping pressure.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Verify the nominal pipe size and ensure the U-bolt's inside dimensions (A and B) are suitable for a snug fit without excessive deformation of the pipe or bolt.
Over-tightening the U-bolt, which can deform the pipe or damage threads.Tighten nuts evenly on both sides until the pipe is securely held, but avoid excessive force that could cause damage. Torque specifications should be consulted if available for the specific application.
Using incompatible or dissimilar metal fasteners, leading to galvanic corrosion.Always use brass nuts and washers with brass U-bolts to maintain the corrosion resistance benefits of the brass material.

Common Applications

  • Marine piping support
  • Chemical processing fluid lines
  • Water and wastewater systems
  • Plumbing in corrosive environments

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts, washers) with brass to prevent galvanic corrosion.
  • Do not exceed the recommended load capacity for the U-bolt and its mounting system.
  • Inspect regularly for signs of wear, corrosion, or loosening, especially in harsh environments.
