Installation Procedure

1. Position the U-bolt around the pipe, ensuring it spans the desired support location. 2. Thread the provided nuts onto the U-bolt legs, hand-tightening initially. 3. Using appropriate wrenches, tighten the nuts evenly on both sides until the pipe is firmly secured against the mounting surface, but avoid over-tightening which can deform the pipe.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Selecting the wrong U-bolt size for the nominal pipe diameter.Always verify the U-bolt's inside width and length against the nominal pipe size and any insulation or outer jacketing.
Using standard carbon steel U-bolts in corrosive environments.For marine, chemical, or other corrosive applications, always specify 316 stainless steel or other suitable corrosion-resistant materials.

Common Applications

  • Marine pipe support systems
  • Chemical processing plant piping
  • Food and beverage industry equipment mounting
  • Wastewater treatment facilities
  • Offshore oil and gas platforms

⚠️ Engineering Warnings

  • Ensure proper thread engagement to achieve rated load capacity.
  • Inspect regularly for signs of corrosion or material fatigue, especially in harsh environments.
