Product description
Medium Clamps
Heavy Duty clamps

Our Hydraulic External Pipe Clamps have a wide gap, which allows the welding of the root up to 90% before removing the clamp. Edge misalignment can be eliminated by means of jackscrews or a wedge which is placed under the alignment bridge.

The air gap can be adjusted by means of chisel. The hydraulic cylinder, which is available as an option, operates in all positions and can be used for all pipe diameters.

Hydraulic External Pipe Clamps - Versions

Medium-duty version

Due to the widely recessed bridges of the hydraulic external pipe centering, up to 90% of the root pass can be welded without loosening the centering. The edge offset is eliminated by driving the splitting iron under the obliquely chamfered bridges.

The product does not contain a hydraulic cylinder.

Heavy-duty version

The hydraulic cylinder works in a vertical position and can be easily changed, if necessary. The alignment bridges have ample clearance, allowing up to 90% root welding before the clamp is removed. For gas pipes (fine-grained steel) and for thick-walled pipes made of studio flat steel.
