Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overtightening the nuts, which can deform the pipe or U-bolt.Use a torque wrench to apply the manufacturer-recommended torque value, or tighten until firm and secure without excessive force.
Using the wrong size U-bolt for the pipe diameter, leading to a loose or damaged installation.Verify the nominal pipe size and corresponding U-bolt dimensions to ensure a proper fit before installation.

Common Applications

  • Marine and offshore installations
  • Chemical processing plants
  • Food and beverage production
  • Wastewater treatment facilities

⚠️ Engineering Warnings

  • Ensure compatibility of other hardware (nuts, washers) with 316 stainless steel to prevent galvanic corrosion.
  • Regularly inspect for signs of wear, damage, or corrosion, especially in highly corrosive environments.
