Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening nuts, leading to pipe deformation or thread stripping.Utilize a torque wrench and adhere to recommended torque specifications for the bolt size and application.
Using a U-bolt with insufficient clearance for insulation or expansion joints.Verify that the U-bolt's inside dimensions (A and B) are adequate for the pipe, any insulation, and expected thermal movement.

Common Applications

  • Marine pipe systems
  • Chemical processing pipelines
  • Potable water systems
  • Sanitary plumbing

⚠️ Engineering Warnings

  • Ensure compatibility of brass with the fluid or environment to prevent galvanic corrosion if dissimilar metals are present.
  • Maximum load ratings are dependent on installation and supporting structure integrity. Consult engineering documentation for specific load limits.
