Detailed Engineering Specifications

A high-performance industrial component, this brass U-bolt is meticulously manufactured to reliably secure 3" nominal pipe diameters. Featuring an inside width (A) of 2.59 inches and an inside length (B) of 2.21 inches, it is designed for a snug fit around the pipe OD. The robust 1/2"-13 UNC thread size ensures significant load-bearing capacity and secure tightening. Fabricated from high-grade brass, it exhibits superior resistance to galvanic corrosion, making it ideal for marine, chemical processing, and other corrosive environments where steel fasteners would degrade rapidly. This component meets stringent industrial standards for structural integrity and longevity.

Installation Procedure

1. Position the U-bolt around the pipe, ensuring it rests evenly on the supporting surface or structure. 2. Thread the nuts onto the U-bolt legs, hand-tightening initially to seat the component. 3. Using appropriate wrenches, tighten the nuts incrementally and alternately to achieve uniform clamping pressure, ensuring the pipe is securely held without deformation. Refer to torque specifications if applicable for the application.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using a steel U-bolt in a corrosive environment.Select a brass U-bolt for applications where corrosion resistance is critical to prevent premature failure and ensure longevity.
Over-tightening the nuts, which can deform the pipe or U-bolt.Tighten nuts to the manufacturer's recommended torque specifications or until firm and secure, avoiding excessive force.
Incorrectly measuring pipe size leading to improper U-bolt selection.Always verify the nominal pipe size and measure the outer diameter (OD) to ensure correct U-bolt dimensions are chosen.

Common Applications
