Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nuts, which can deform the pipe or the U-bolt.Tighten nuts to the manufacturer's recommended torque specification for the pipe and mounting surface.
Using the wrong size U-bolt for the pipe diameter, leading to a loose or damaging fit.Always verify the pipe's nominal size and select a U-bolt with the appropriate inside width (A) to ensure a snug and secure fit.

Common Applications

  • Plumbing and HVAC pipe support
  • Chemical processing equipment mounting
  • Marine and offshore structural support

⚠️ Engineering Warnings

  • Ensure compatibility of 304 stainless steel with the specific environmental conditions and fluids it will be exposed to.
  • Do not exceed the rated load capacity of the U-bolt and its mounting hardware.
