Custom U Bolt Clamps Single Plate Type for Horizontal Flat Tapes

คำอธิบาย

U bolt clamps are specialized fasteners consisting of a U-shaped bolt paired with a metal plate or saddle, designed to securely clamp pipes, cables, or flat surfaces to fixed structures. U bolt clamps provide high tensile strength, vibration resistance, and adaptability to various shapes and sizes.

Specifications of U Bolt Clamps (Single Plate Type for Horizontal Flat Tapes)

1. Material

• U-Bolt:

  • Carbon Steel (Grade 4.8/8.8): General-purpose, cost-effective.

  • Stainless Steel (304/316): Corrosion-resistant for outdoor/marine use.

• Plate (Saddle):

  • Galvanized Steel: Rust-proof for industrial applications.

  • Aluminum: Lightweight, non-corrosive for electrical/telecom.

2. Surface Treatment

• Hot-Dip Galvanized: Heavy-duty corrosion protection (e.g., bridges, pipelines).

• Electro-Galvanized: Smooth finish for moderate environments.

• Powder-Coated: Aesthetic + abrasion-resistant (architectural/urban infrastructure).

3. Common Specifications

• Bolt Diameter: 6mm–24mm (M6–M24).

• Plate Width: 20mm–100mm (customizable to tape width).

• Thread Type: Metric (M6–M24) or UNC/UNF.

• Standards: DIN 3570, ISO 1461, ASTM A153.

4. Applications

• Electrical: Securing flat busbars or grounding tapes in substations.

• Telecom: Fixing fiber-optic cables to poles/towers.

• Construction: Anchoring flat steel straps in HVAC/plumbing systems.

• Transportation: Fastening cargo straps to truck/trailer beds.

Excellent Case: Earthquake-Resistant Cable Management in Subway Tunnels

Challenge:
A metro system needed to prevent power/communication cable sagging or displacement during seismic activity, which risked service outages.

Solution:

• Deployed stainless steel U-bolt clamps (Single Plate Type, 316SS) with M12 bolts to horizontally secure flat copper grounding tapes to tunnel walls.

• Key Features:

  • Vibration Resistance: Withstood 8.0-magnitude simulated quakes without loosening.

  • Corrosion Proof: 316SS resisted tunnel humidity and chemical exposure.

  • Easy Inspection: Single-plate design allowed quick visual checks.

Result:

• Zero cable failures over 5 years, reducing maintenance costs by 50%.

Key Advantages Summary

✔ High Load Capacity – Clamps flat tapes without deformation.
✔ Safety Compliance – Meets seismic/electrical safety standards (e.g., IEC 62444).
✔ Customizable – Adjustable plate width/bolt length for unique tape thicknesses.
