Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using undersized or oversized U-bolts for the pipe diameter.Always verify the nominal pipe size and select a U-bolt with matching inside dimensions to ensure a proper and secure fit.
Over-tightening the nuts, which can deform the pipe or the U-bolt.Use a torque wrench to tighten nuts to the recommended specification for the pipe material and application to prevent damage.
