Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it rests within the saddle or mounting surface. 2. Thread the nuts onto the U-bolt legs, initially hand-tightening to snug the component. 3. Gradually tighten the nuts in an alternating pattern to achieve uniform pressure, ensuring the pipe is securely held without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening, leading to pipe deformation or thread stripping.Utilize a torque wrench to adhere to recommended torque specifications for the chosen thread size and material, ensuring secure fastening without overstress.
Using the wrong size U-bolt for the pipe diameter.Always verify the Inside Width (A) and Inside Length (B) of the U-bolt against the nominal pipe size and any required clearances for optimal fit and support.

Common Applications

  • Marine pipe support
  • Chemical processing equipment mounting
  • Offshore platform infrastructure

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts and washers) with 316 stainless steel to prevent galvanic corrosion.
  • Avoid exposing to chlorides at elevated temperatures, which can still induce stress corrosion cracking in even the most resistant stainless steels.
