Duoline Technologies 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. 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.

Headquartered in Gilmer, Texas, Duoline Technologies has combined forces with international partners who each will provide DUOLINE products and services for their respective territories. MaxTube Ltd. , with a DUOLINE® lining facility base in Scotland and U.A.E. provides Duoline service to the North Sea, Europe, and the Middle East. Duoline® products are represented in Brazil by Nova Coating and in the U.S. by PetroSmith. Rice Engineering & Operations LTD. operates a Duoline® lining facility in Edmonton, Alberta, Canada.
