Installation Procedure

1. Select appropriate washers and hex nuts for the 1/2"-13 thread size. 2. Position the U-bolt around the 3" pipe, ensuring it rests securely within the U-bolt's radius. 3. Place washers and thread hex nuts onto the bolt legs, hand-tightening initially. 4. Use calibrated torque wrenches to tighten nuts to the specified torque, ensuring even pressure on both legs for secure clamping.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the pipe diameter.Always verify the nominal pipe size against the U-bolt's internal width and length specifications to ensure a proper fit.
Over-tightening or uneven tightening of nuts.Utilize calibrated torque wrenches and tighten nuts in an alternating pattern to achieve uniform clamping force and prevent deformation.
Using standard carbon steel hardware with 316 stainless steel U-bolts.Always use 316 stainless steel or compatible high-grade hardware to maintain corrosion resistance and prevent galvanic corrosion.

Common Applications

  • Marine and offshore structural support
  • Chemical processing plant pipe securing
  • Wastewater treatment facility infrastructure
  • Industrial plumbing and conduit mounting

⚠️ Engineering Warnings

  • Ensure compatibility of mating hardware (nuts and washers) with 316 stainless steel to prevent galvanic corrosion.
  • Do not exceed the rated load capacity or torque specifications to maintain structural integrity.
