Duoline Technologies, a member company of the Robroy Industries Group, found its beginnings in the oilfield industry designing, installing and operating produced saltwater gathering & disposal systems since 1953. Through these endeavors, Duoline Technologies developed the DUOLINE lining process in 1964 as a means to solve our own downhole steel tubular corrosion problems.
