Large Diameter Screw Jack
Internal Alignment Clamps:

The simple answer for internal aligning of any large O.D. pipe.

Individual jackscrews allow for specific pressure application on any particular area while still aligning the total pipe gap.

Internal alignment application increases production and welding.

Wheel mounted for ease of operation and internal pipe mobility.

Available in sizes 48" through 144"
