Installation Procedure

1. Position the U-bolt around the 4" nominal pipe, ensuring it straddles the pipe evenly. 2. Secure the U-bolt by threading the provided nuts onto the bolt ends, tightening them incrementally and evenly. 3. Ensure the U-bolt is firmly seated against the pipe and the mounting surface, and that no excessive stress is applied to the pipe itself.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the pipe or the U-bolt.Tighten nuts to a snug fit, then apply an additional quarter to half turn. Refer to torque specifications if available.
Using the wrong size U-bolt for the pipe, leading to a loose or damaging fit.Always verify the nominal pipe size and U-bolt dimensions (Inside Width A and Inside Length B) before installation.

Common Applications

  • Marine piping systems
  • Chemical processing plant infrastructure
  • Offshore oil and gas platforms
  • Food and beverage processing lines
  • Wastewater treatment facilities

⚠️ Engineering Warnings

  • Ensure compatibility with the fluid or gas being transported to prevent material degradation.
  • Always use appropriate personal protective equipment (PPE) during installation.
