Small Bore VBR Front Packers for Cameron Type VBR Ram Blocks

By: Cpi  09-12-2011

These Variable Bore Ram (VBR) packers with the new and improved straight sided metal inserts that limit upward rubber extrusion from well bore pressure between the segments and the pipe as shown. The segments are also overlapped to limit upward rubber extrusion between them. The rubber should be compressed and sealing around the drill pipe and not extruding upward. Variable Bore Ram (VBR) packers are expensive and longer working life is a cost saving measure. Day rate is saved by changing fewer Variable Bore Ram (VBR) packers.
