Company History
Duoline Technologies, a Maxtube Group company since 2017, 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 1963 as a means to solve our own downhole steel tubular corrosion problems. Since that time we have installed more than 100 million feet of DUOLINE tubing worldwide. DUOLINE’s unmatched performance has made it the most successful system for prevention of downhole tubular corrosion.
Maxtube found its beginnings in 1996 as the licensee of Duoline® Technologies Inc, TX, USA. Duoline® Technologies are the pioneers in developing the Fiberglass / Glass-reinforced epoxy lining process to solve downhole steel tubular corrosion problems since 1963. The companies developed the first lining system for unmodified premium connections in collaboration with connection licensors in 2004. The Duoline® lining technology now has a global footprint installed in more than 55,000 wells and 110 million feet across the 6 continents in major IOCs and NOCs making it the most successful system for downhole corrosion prevention. Carbon steel lined with Duoline® has been applied as a cost-effective alternative to CRA tubing in gas and oil production applications. The Duoline® technology has flow assurance and flow enhancement benefits eliminating the deposition of scales, asphaltene, wax, and improving the flow dynamics in downhole tubing. The Duoline® technology has also made its presence in surface flowline applications. Maxtube acquired Duoline® Technologies Inc. in 2017 bringing R&D, production, testing, the application under one roof becoming a single stop shop offering operators corrosion and flow assurance solutions in technically and commercially attractive terms.
