DUOLINE ® TECHNOLOGIES INTRODUCES…
Reliable corrosion protection of steel tubulars
with temperature resistance up to 350°F/177°C.
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.
