Installation Procedure

1. Verify the U-bolt's inside dimensions are appropriate for the 3" nominal pipe diameter. 2. Position the U-bolt around the pipe, ensuring it is centered on the desired support point. 3. Secure the U-bolt by threading the provided nuts onto the threaded legs, tightening evenly on both sides with calibrated torque wrenches to the manufacturer's recommended specification.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting a U-bolt with insufficient inside width for the pipe's actual outer diameter.Always measure the outer diameter of the pipe to be supported and cross-reference with the U-bolt's inside width specification for a precise fit.
Under-tightening or over-tightening the U-bolt nuts, compromising load-bearing capacity or damaging the pipe/support.Utilize a calibrated torque wrench to apply the manufacturer-specified torque to ensure optimal clamping force and prevent overstress.

Common Applications

  • Marine and offshore structural support
  • Chemical and petrochemical piping systems
  • Food and beverage processing lines

⚠️ Engineering Warnings

  • Ensure all hardware (nuts, washers) is also corrosion-resistant, ideally 316 stainless steel, to prevent galvanic corrosion.
  • Consult relevant engineering codes and standards for specific application load requirements and permissible stresses.
