Learn how to beat the high cost of oilfield and gasfield corrosion...
This unique insert liner process secures a corrosion resistant material such as GRE (glass- reinforced-epoxy) or PVC (polyvinyl chloride) inside the steel pipe. The benefit? Isolation of corrosive oilfield fluids and gases from the steel.

The cost of replacing failed downhole production tubing or subsea flowlines is extremely high. Duoline® products offer an unsurpassed record for prevention of corrosion in very demanding conditions. Duoline® Technologies offers cost-effective superior performance compared to the less durable option of spray-on coatings.
