    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.
