Precision-manufactured to tight tolerances, this U-bolt is constructed from premium 316 stainless steel, renowned for its exceptional resistance to chloride pitting and crevice corrosion, making it suitable for marine, chemical, and food processing environments. The U-bolt features an inside width (A) of 3.22 inches and an inside length (B) of 5.22 inches, specifically designed to accommodate standard 3-inch nominal pipe sizes. The threads are a robust 1/2"-13 UNC (Unified National Coarse) size, ensuring secure fastening with corresponding nuts and washers. The material's high tensile strength and ductility provide reliable load-bearing capacity under 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-inch pipe, ensuring it is centered and square. 2. Place the provided saddle or mounting surface against the pipe and through the U-bolt legs. 3. Thread the 1/2"-13 nuts onto the U-bolt legs and tighten evenly to secure the pipe. Do not overtighten.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong size U-bolt for the pipe diameter. | Always verify the pipe's nominal and actual outside diameter against the U-bolt's inside dimensions (A) and (B) before installation. |
| Using standard carbon steel U-bolts in corrosive environments. | For applications exposed to moisture, saltwater, or chemicals, always select 316 stainless steel for superior corrosion resistance and longevity. |
| Uneven tightening of nuts, leading to stress concentration. | Tighten nuts incrementally and evenly on both legs of the U-bolt to distribute stress uniformly and prevent pipe deformation. |
