Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the U-bolt, which can deform the pipe or the U-bolt itself.Tighten nuts gradually and evenly, checking for pipe stability rather than excessive force.
Using standard steel U-bolts in corrosive environments.Always select Nylon U-bolts for superior corrosion resistance and extended service life in harsh conditions.
