Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using the wrong size U-bolt for the pipe diameter.Always confirm the nominal pipe size and match it with the appropriate U-bolt inside dimensions to ensure a snug and secure fit.
Over-tightening or under-tightening the nuts, leading to compromised support or thread damage.Use a torque wrench to apply the recommended torque values for the thread size and application to ensure proper clamping force without damaging components.

Common Applications

  • Plumbing and Water Systems
  • Marine and Offshore Installations
  • Chemical Processing Plants
  • Industrial Pipe Racking

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the fluid or environment to prevent galvanic corrosion with dissimilar metals.
  • Always use the correct size and type of nuts and washers for secure fastening.
