DUOLINE® Technologies – the global leader in fiberglass internal lining systems for protecting oilfield tubulars – is proud to announce the development of a higher temperature resistant product: D-350.

Here are the benefits to you:
Reliable temperature resistance up to 350°F (177°C)
Proven to maintain mechanical and chemical resistance similar to that of Duoline® Technologies' successful D-20 lining system.
Consists of a seamless glass reinforced filament wound liner wrapped in a continuous helical pattern to provide the greatest tensile and hoop strengths.
Glass is saturated during the winding process with a proprietary aromatic amine resin formulation providing fusion between the fibers. This ensures a holiday-free, flawless liner.
Saturation of fibers with resin provides chemical resistance required to prevent corrosion attack of the steel tubulars.
Liners are cured by applying internal heat to a hollow mandrel. This ensures that encapsulated air pockets do not occur on the liner's bodywall, a major differentiation from liners produced using a thermal cure cycle which cures the outer diameter first and increases the potential for product failure by encapsulating air pockets on the liner's bodywall.
