Made from high quality steel or stainless steel with an elastomer outer skin with a profiled sealing system, the Expandable Steel Patch is run on tubing, drill pipe and coiled tubing. At depth the Patch is expanded using a high pressure inflatable packer, and pushed against the casing to activate the outer seals. The setting tools are extracted to leave a pressure resistant inner lining inside the well.
