Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it straddles the pipe and rests on a suitable mounting surface or bracket. 2. Thread the provided nuts onto both ends of the U-bolt, ensuring they are started evenly. 3. Tighten the nuts alternately and progressively to achieve the specified clamping force, ensuring the pipe is held securely without deformation.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong U-bolt size for the nominal pipe diameter.Always verify the U-bolt's internal dimensions (width and length) against the specific pipe's outside diameter and the intended mounting configuration.
Over-tightening the nuts, potentially deforming the pipe or U-bolt.Tighten nuts alternately and to the manufacturer's recommended torque specifications, ensuring even pressure is applied.
Using standard carbon steel U-bolts in corrosive environments.Select 304 or 316 stainless steel for applications exposed to moisture, chemicals, or saltwater to prevent premature corrosion and failure.

Common Applications

  • Pipe support and clamping in chemical processing plants
  • Marine and offshore structural applications
  • Food and beverage processing equipment mounting

⚠️ Engineering Warnings

  • Ensure all fasteners are torqued to specifications to prevent loosening or damage.
  • Inspect regularly for signs of corrosion or wear, especially in harsh environments.
