Installation Procedure

1. Position the U-bolt to straddle the pipe, ensuring the curved section fully contacts the pipe's outer diameter. 2. Thread the nuts onto both ends of the U-bolt, hand-tightening initially to achieve proper alignment. 3. Utilize a calibrated torque wrench to tighten the nuts to the manufacturer-specified torque value, ensuring even pressure distribution on both sides of the pipe.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the nuts, leading to pipe deformation or damage.Always use a calibrated torque wrench and adhere to the recommended torque specifications for the pipe size and material.
Selecting a U-bolt with incorrect dimensions, resulting in a loose or overly restrictive fit.Verify the pipe's actual outer diameter and compare it with the U-bolt's inside dimensions (width and length) before purchase.
