Specified by design engineers worldwide, this U-bolt is manufactured from premium 316 stainless steel, offering exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, even in highly aggressive environments. The precise dimensions, including an inside width (A) of 3.58 inches and an inside length (B) of 3.37 inches, are optimized for snug and secure clamping of 3" nominal pipe. The standard 1/2"-13 UNC thread size ensures broad compatibility with common mounting hardware, facilitating straightforward integration into engineered systems. This specification guarantees structural integrity and longevity in demanding operational conditions.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Position the U-bolt around the 3" nominal pipe, ensuring it sits flush against the supporting structure. 2. Thread the 1/2"-13 nuts onto the U-bolt legs, hand-tightening initially to secure the pipe. 3. Using appropriate torque wrenches, tighten the nuts evenly in an alternating pattern to the manufacturer's recommended torque specification for the 1/2"-13 thread size, ensuring consistent pressure and eliminating pipe movement.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-tightening the U-bolt nuts, which can deform the pipe or the U-bolt itself. | Adhere strictly to the recommended torque specifications for the 1/2"-13 thread size, utilizing a calibrated torque wrench for accurate application. |
| Using a lower-grade stainless steel or carbon steel in corrosive environments, leading to premature failure. | Always select 316 stainless steel for applications exposed to saltwater, chemicals, or high humidity to ensure long-term corrosion resistance and system integrity. |
