The workhorse of the DUOLINE lining systems, DUOLINE 20, developed by DUOLINE TECHNOLOGIES in 1971, is targeted for the majority of downhole corrosive applications. 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 formation temperatures as high as 292°F (144°C), and is typically used in water injection and gas production service up to 250°F (121°C).

The MaxTube installation system is completely portable and our Portable Lining Units (PLU's) have lined pipe for blue chip national and independent oil companies in over 20 countries.
