DUOLINE® 20, manufactured by Maxtube’s Duoline Technologies, is a filament-wound Glass-Reinforced Epoxy (GRE) liner which is installed to OCTG in corrosive service. It is widely accepted that GRE lining is a more robust alternative to internal plastic coating. DUOLINE® 20 is a very effective corrosion barrier with a long history of tubular protection in a variety of offshore and landbased applications.

The workhorse of the DUOLINE® lining systems. DUOLINE® 20, developed in 1971, is targeted for more demanding corrosive downhole environments. The DUOLINE® 20 system has a proven track record in a great number of demanding environments including water injection, CO2 injection, gas production, gas-lifted oil production and chemical disposal wells, onshore and offshore. DUOLINE® 20 has an outstanding performance history in environments containing produced fluids and gasses with CO2 and H2S. DUOLINE® 20 has successfully prevented corrosion in gas production wells with BHT as high as 292°F (144°C), and is typically used in water injection and gas production service up to 284°F (140°C) dependent on well conditions.

DUOLINE® 20 has proven to be the most abrasion resistant coating or lining product in downhole wireline trials in deviated wells. It is acid compatible, impact resistant, resistant to gas service failures common to other coatings or linings, premium connection compatible, chemically resistant and tolerant to common tension and bending loads. Quite simply, DUOLINE® 20 offers unsurpassed corrosion protection by a lining system.
