Without special coupling, corrosion barriers enable GRE internal liner placing

DL-Ring corrosion barrier system

"DL-Ring" corrosion barrier systems help you place GRE internal liners inside any shoulder-to-shoulder premium thread without need for a special coupling.

The patent-pending connection technology "permits the lining to accommodate any proprietary premium connection."

"DL-Ring" is wireline abrasion and chemically corrosion-resistant in controlled lab testing and in more than 75,000-ft of downhole application. These attributes help accomplish internal corrosion protection using a glass-reinforced-epoxy lining system for oilfield steel tubing and line pipe.

Two DL-flares place the DL-CBR in compression during field make-up. The concept and material composition have been used extensively and successfully with DUOLINE tubing in numerous other "FGL' versions of modified premium and API connections.
