Installation Procedure

1. Position the U-bolt around the pipe, ensuring it straddles the supporting structure. 2. Thread the nuts onto the U-bolt legs, hand-tightening initially. 3. Evenly tighten the nuts using a wrench to achieve the required clamping force, ensuring the pipe remains securely fastened without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the pipe diameter.Always verify the inside width (A) of the U-bolt against the nominal pipe size to ensure a proper fit.
Insufficient or uneven tightening of the nuts.Tighten nuts incrementally and alternately to distribute clamping force evenly, preventing pipe distortion and ensuring secure attachment.

Common Applications

  • Marine pipe support
  • Chemical processing equipment
  • Outdoor structural fastening
  • Plumbing and conduit support

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts and washers) with 316 stainless steel to prevent galvanic corrosion.
  • Do not overtighten, as this may deform the pipe or damage the U-bolt threads.
