Abstract:
1. A device to separate a first pipe having a first pipe flange and a second pipe having a second pipe flange, wherein said first pipe flange and said second pipe flange are bonded at a flange joint comprising: an elongated frame having a front end and a back end; a frame retaining plate connected to said front end, whereby said frame retaining plate is placed adjacent to said first pipe flange so that said frame extends over said flange joint, and whereby said frame retaining plate prevents longitudal slippage of said device; a pusher pin having a pusher pin top end and a pusher pin bottom end, located a first distance along said frame from said frame retaining plate, wherein said pusher pin is capable of moving transversely between a first retracted position and a first extended position; a leveling pin having a leveling pin top end and a leveling pin bottom end, located at said back end, wherein said leveling pin is capable of moving transversely between a second retracted position and a second extended position, and whereby when said leveling pin is pushed to said second extended position, said device is stabilized against said second pipe; an anchoring pin having an anchoring pin top end and an anchoring pin bottom end, located between said pusher pin and said leveling pin along said frame, wherein said anchoring pin bottom end contains a member which extends toward said flange joint and is configured to anchor said anchoring pin to said second pipe flange; and whereby when said anchoring pin is anchored to said second pipe flange, and said pusher pin is pushed to said first extended position to apply a transverse force on said first pipe flange, said first pipe flange and said second pipe flange slide in opposite directions from each other and are separated.
