Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it sits flush against the mounting surface. 2. Insert appropriate flat and lock washers onto the threaded ends of the U-bolt. 3. Thread the 1/2"-13 nuts onto the bolt ends and tighten them evenly to secure the pipe. Avoid over-tightening to prevent pipe deformation.

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 select a U-bolt with the correct inside dimensions (width and length) to ensure a snug and secure fit.
Over-tightening the nuts, leading to pipe damage or deformation.Tighten nuts evenly in a star pattern to apply consistent pressure. Stop when the pipe is firmly held, but do not crush or deform the pipe wall.
Failing to use washers, which can lead to fastener loosening and uneven pressure distribution.Always use both a flat washer to distribute the load and a lock washer to prevent loosening due to vibration.

Common Applications

  • Plumbing and HVAC pipe support
  • Marine and offshore applications
  • Chemical processing and industrial piping systems

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the fluid or environment to prevent premature corrosion.
  • Use appropriate torque specifications to avoid over-stressing the pipe or U-bolt.
