A proven choice for industrial professionals, this 316 stainless steel U-bolt is engineered to securely fasten 4" nominal pipes. It features an inside width (A) of 4.13 inches and an inside length (B) of 5.33 inches, ensuring a precise fit. The robust 1/2"-13 thread size provides a strong and reliable connection, capable of withstanding significant tensile loads. The inherent properties of 316 stainless steel, including its high molybdenum content, provide superior resistance to pitting and crevice corrosion, making it ideal for marine, chemical processing, and food & beverage industries where aggressive media is prevalent.
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 pipe, ensuring the pipe is centered within the U-bolt's width. 2. Thread the nuts onto the U-bolt legs until snug against the mounting surface or pipe saddle. 3. Tighten the nuts alternately to achieve uniform pressure and a secure, stable fit, but avoid over-tightening which can deform the pipe.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong U-bolt size for the nominal pipe diameter, leading to loose or damaged pipe. | Always verify the nominal pipe size and select a U-bolt with matching or slightly larger inside dimensions to accommodate insulation if present. |
| Over-tightening nuts, which can crush the pipe or distort the U-bolt threads. | Tighten nuts evenly and progressively. Consult torque specifications for the specific application if critical. |
| Using carbon steel U-bolts in corrosive environments, leading to premature failure. | Always select 316 stainless steel or equivalent corrosion-resistant materials for applications exposed to moisture, chemicals, or salt. |
