DUOLINE 20

The workhorse of the DUOLINE lining systems. DUOLINE 20, developed by Rice Engineering 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 DUOLINE 20 liner is fabricated exclusively by Rice Engineering. The liner is a GRE composite (glass reinforced epoxy resin system) manufactured with a filament winding & high temperature cure process. The only fiberglass-epoxy lining system in the marketplace today with over 27 years of accumulated field history. Rice Engineering and DUOLINE 20 have pioneered the acceptance of fiberglass-lined pipe around the world. DUOLINE 20 is manufactured and available in a number of international locations.

DUOLINE 20 has proven to be the most abrasion tolerant coating or lining in downhole wireline trials completed in deviated wells. It resists gas service failures common to other coatings or linings, is premium connection compatible, as well as unyielding to common tension and bending loads while also offering proven chemical resistance. Quite simply, DUOLINE 20 offers unsurpassed corrosion protection by a lining system.
