Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening, causing pipe deformation or damage.Refer to torque specifications for the specific application and use a calibrated torque wrench for accurate tightening.
Using incorrect size U-bolt for the pipe diameter.Always verify the nominal pipe size and the U-bolt's inside dimensions (Width A) to ensure a proper fit and secure support.

Common Applications

  • Pipe hanging and support systems
  • Securing conduit and electrical raceways
  • Structural framing and bracing

⚠️ Engineering Warnings

  • Ensure proper torque is applied to avoid over-stressing the pipe or U-bolt.
  • Inspect U-bolts regularly for signs of corrosion or wear, especially in harsh environments.
