Detailed Engineering Specifications

Purpose-built for heavy-duty applications, this brass U-bolt provides robust support for 3-inch nominal pipe sizes. The material, solid brass (e.g., UNS C26000 cartridge brass or equivalent), offers exceptional resistance to galvanic corrosion, ideal for saltwater and chemical exposure. Its dimensions are precisely manufactured with an Inside Width (A) of 2.69 inches and an Inside Length (B) of 2.49 inches, ensuring a snug and secure fit around standard 3" pipe schedules. The 1/2"-13 UNC (Unified National Coarse) thread size on each leg allows for secure fastening with compatible nuts (sold separately), delivering reliable structural integrity in demanding industrial and marine settings.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel U-bolt in a corrosive environment.Always select brass or other corrosion-resistant materials like stainless steel for applications exposed to saltwater, chemicals, or high humidity to prevent premature failure.
Overtightening the nuts, which can deform the pipe or the U-bolt.Tighten nuts firmly but avoid excessive force. Use a torque wrench if specific torque values are critical for the application to prevent damage and ensure longevity.

Common Applications

  • Marine pipe support
  • Chemical processing systems
  • Plumbing and water systems in corrosive areas
  • Offshore structures
  • Industrial exhaust systems

⚠️ Engineering Warnings

  • Ensure compatibility of mating nuts with the 1/2"-13 thread size.
  • Verify the U-bolt's load capacity is sufficient for the pipe and its contents.
