Trusted by engineers across multiple sectors, this U-bolt is constructed from high-grade 304 stainless steel, offering excellent resistance to pitting and crevice corrosion, making it suitable for a wide array of chemical and marine applications. Featuring an inside width (A) of 1.72 inches and an inside length (B) of 4.83 inches, it accommodates standard 3-inch nominal pipes. The robust 1/2"-13 UNC thread size ensures secure fastening with compatible nuts and plates, providing reliable structural integrity for pipe systems under moderate loads and varying environmental 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 nominal pipe, ensuring it aligns with the mounting surface. 2. Place the provided or compatible flat or saddle washers onto the threaded legs. 3. Secure the assembly by threading the nuts onto the U-bolt legs, tightening evenly on both sides until firm, but avoid overtightening. 4. For critical applications, verify torque specifications against the load requirements and mounting surface capabilities.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Selecting the wrong U-bolt size for the pipe's nominal diameter. | Always confirm the U-bolt's inside dimensions (width and length) are appropriate for the specific nominal pipe size being supported, accounting for insulation if present. |
| Using a U-bolt in a corrosive environment without verifying material compatibility. | Ensure the 304 stainless steel grade is suitable for the specific chemical or environmental exposure. For more aggressive conditions, consider higher grades like 316 stainless steel. |
| Uneven tightening of the U-bolt nuts, leading to stress concentrations. | Tighten nuts incrementally and alternately on each leg to ensure uniform clamping force and distribute stress evenly across the pipe and mounting surface. |
