Installation Procedure

1. Position the U-bolt around the pipe, ensuring it rests evenly on the supporting structure or mounting plate. 2. Thread the provided nuts onto the U-bolt legs, hand-tightening initially. 3. Using appropriate wrenches, tighten the nuts progressively and evenly until the pipe is securely held, avoiding overtightening which could deform the pipe or U-bolt.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting a U-bolt with insufficient inside width for the actual pipe OD.Always measure the Outer Diameter (OD) of your pipe and select a U-bolt with an inside width that accommodates it comfortably, typically allowing for pipe wall thickness.
Using carbon steel U-bolts in corrosive environments.For marine, chemical, or outdoor applications, always opt for 304 or 316 stainless steel to prevent rust and premature failure due to corrosion.

Common Applications

  • Marine pipe and conduit support
  • Chemical processing plant installations
  • Plumbing and HVAC systems
  • Structural framework attachment

⚠️ Engineering Warnings

  • Ensure nuts and washers are compatible with 304 stainless steel to prevent galvanic corrosion.
  • Do not exceed the recommended load rating for this U-bolt; consult engineering specifications for load capacity.
