Double Bolted Clamp

Product Description

Double Bolted Clamp

A double bolted clamp is a heavy-duty fastening device characterized by a two-part semi-circular design secured by two separate bolts. Unlike standard single-bolt clamps (like a typical hose clamp), the dual-bolt configuration allows for significantly higher torque and more uniform radial pressure.

Primary Design & Function

• Two-Piece Construction: These clamps consist of two interlocking or mirroring halves. This design allows the clamp to be installed on existing piping or hosing systems without needing to slide it over a free end.

• High Clamping Force: By tightening two bolts—usually situated on opposite sides—the clamping force is distributed evenly around the circumference of the object. This prevents the "pinching" or "gapping" that can occur with single-bolt designs.

• Reinforcement: Many versions feature an inner "tongue" or a "bridge" that spans the gap between the two halves, ensuring 360° contact and preventing the hose material from bulging through the bolt gaps.

Key Types and Applications

1. Hose Clamps (Industrial): Used for heavy-duty suction and discharge hoses in agriculture, mining, and construction. They are often used with "interlocking" hose nipples to prevent the hose from blowing off under high pressure.

2. Pipe Support Clamps: Used in plumbing and HVAC to secure rigid pipes to walls or ceilings. The double-bolt design allows the clamp to support the weight of the pipe while also absorbing vibrations.

3. Split Muffler Clamps: Common in automotive exhaust systems, these connect two pipes of the same or slightly different diameters, providing a gas-tight seal that can withstand high temperatures and road vibration.

Technical Specifications

Advantages

• Reusability: These clamps are rugged and can be disassembled and re-installed multiple times without losing structural integrity.

• Security: The use of two bolts provides a mechanical redundancy; if one bolt were to experience tension loss, the second bolt helps maintain the seal.

• Versatility: They are effective for securing high-durometer (stiff) hoses that require massive compression to create a seal.

Installation Note

For the most effective seal, it is best practice to tighten the bolts alternately and in small increments. This ensures the two halves of the clamp close evenly and maintain a perfect circle around the hose or pipe.
