Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it sits flush against the mounting surface. 2. Thread the appropriate nuts onto the U-bolt legs, hand-tightening initially. 3. Use calibrated torque wrenches to tighten the nuts evenly to the manufacturer's recommended torque specification for the M12 thread size, ensuring consistent pressure on the pipe and mounting surface.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using carbon steel U-bolts in corrosive environments.Always specify brass or stainless steel U-bolts for applications exposed to saltwater, chemicals, or high humidity to prevent premature corrosion and failure.
Incorrectly sizing the U-bolt for the pipe diameter.Verify the pipe's nominal diameter and ensure the U-bolt's inside width and length are appropriate for a snug, secure fit without deforming the pipe.

Common Applications

  • Marine pipe support
  • Chemical processing equipment
  • Plumbing systems in coastal areas

⚠️ Engineering Warnings

  • Ensure all fasteners (nuts and washers) are also made of brass or a compatible corrosion-resistant material.
  • Do not exceed the recommended torque specifications during installation to prevent damage to the pipe or mounting structure.
