Some typical applications for flange spreaders are; pipe and flange repair, removing elbows, coupler/gasket/metal seal replacement and heavy equipment maintenance.

With your hydraulic spreader you will require; a hose, manifold, safety blocks, split flow manifold, pressure gauge and a hand (or air) operated pump.

Flange spreading is a specialist skill, so should only be carried out by trained personnel.
