Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this 3" pipe U-bolt features an Inside Width (A) of 3.80 inches and an Inside Length (B) of 7.87 inches, accommodating standard 3-inch nominal pipe sizes. The U-bolt is forged from high-impact, UV-stabilized polycarbonate, providing exceptional resistance to a wide range of chemicals, acids, and alkalis, making it ideal for marine, chemical processing, and water treatment applications. The 1/2"-13 UNC thread size ensures secure fastening with standard nuts and washers. Its non-metallic composition eliminates galvanic corrosion, a critical advantage over traditional metal fasteners in corrosive atmospheres.

Installation Procedure

1. Position the U-bolt around the 3" pipe, ensuring it rests securely on the pipe's outer diameter. 2. Insert the threaded legs through the mounting holes of the supporting structure or bracket. 3. Attach nuts and washers to the threaded ends, tightening evenly to achieve firm but not excessive clamping force, avoiding over-compression of the polycarbonate.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the nutsTighten nuts incrementally and evenly. Polycarbonate can be brittle under excessive localized stress. Use a torque wrench if precise values are required by the application.
Using for applications exceeding its temperature or load ratingConsult the product's technical data sheet for specific temperature limits and load capacities. Do not use in environments where these limits may be exceeded without consulting the manufacturer.

Common Applications

  • Chemical processing plants
  • Wastewater treatment facilities
  • Marine and offshore installations
  • Food and beverage processing
  • Plumbing and conduit support in corrosive areas

⚠️ Engineering Warnings

  • Ensure compatibility with specific chemicals and environmental conditions.
  • Avoid exposure to temperatures outside the specified operating range.
  • Do not use as a structural support element unless explicitly rated and approved for such use.
