Installation Procedure

1. Position the U-bolt around the 3" nominal pipe, ensuring the pipe rests securely within the curve. 2. Place the provided or appropriate flat washers onto each threaded leg of the U-bolt. 3. Thread the corresponding nuts onto the U-bolt legs and tighten them evenly and progressively to achieve the desired clamping force, as specified by system requirements. Ensure nuts are fully engaged on the threads.

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 against the U-bolt's internal dimensions (A and B) to ensure a proper fit and secure support.
Over-tightening or uneven tightening of the nuts.Tighten nuts evenly and progressively. Over-tightening can deform the pipe or U-bolt, while uneven tightening can lead to stress concentrations and potential failure. Consult system-specific torque recommendations if available.
Using standard carbon steel nuts and washers with a stainless steel U-bolt.Always use stainless steel nuts and washers (ideally 304 or 316 grade) with 304 stainless steel U-bolts to prevent galvanic corrosion and maintain the integrity of the assembly.

Common Applications

  • Piping and conduit support in chemical processing plants
  • Marine and offshore structural applications
  • Plumbing and HVAC systems in corrosive environments

⚠️ Engineering Warnings

  • Ensure proper thread engagement when tightening nuts to avoid stripping or failure.
  • For critical applications or extreme environments, consult with a qualified engineer to confirm material suitability and load-bearing capacity.
