Well Flange Separation

ThinJack is a unique splitting and separating service that effectively separates well flanges. The ThinJacks themselves are usually curved steel envelopes less than 3mm thick which are inserted between the 2 items for separation. In this application, they are made to fit between the flange’s bolt holes and the outer edge.
