“Manual cage pipe clamps” typically refer to mechanical clamps used to securely hold and align pipes—especially in pipeline construction or welding—without the use of hydraulics or motors. These clamps are often used during pipe welding, fit-up, or fabrication processes to ensure correct pipe alignment and maintain gap spacing.
Key Features of Manual Cage Pipe Clamps:
Manual Operation: Adjusted using hand-operated screws or levers.
Cage Design: Open-frame or “cage”-like structure surrounds the pipe to provide stable alignment.
Range of Sizes: Often adjustable or available in models that fit specific pipe diameters.
Materials: Usually made from steel or cast iron for durability.
Applications: Used in industries like oil and gas, construction, shipbuilding, and pipeline fabrication.
Types:
Single Chain Cage Clamps – For basic pipe-to-pipe alignment.
Dual Chain or Gear Drive Cage Clamps – Offer more even pressure and better control.
Tack-Type Manual Cage Clamps – Allow tacking (temporary welding) while holding pipes.
Benefits:
Portable and lightweight compared to hydraulic models.
No need for external power.
Durable and simple to use in field conditions.
