TechnowrapTM 2K high ambient chemical injection drip pan

Scope
ICR was asked to offer a solution to reinstate a production chemical injection skid pan experiencing localised pitting, wall loss, and through-wall defects of varying sizes. Structural capacity was a minor consideration as loads were small, and the primary goal was to provide containment of fluids.
Solution
ICR proposed two layers of Technowrap 2K™ substrate with Technowrap HA™ (High Ambient) resin, with localised plates over numerous through-wall defects. The repair would fully cover the skid pan and ensure proper pan gradient for draining fluids. The repair was based on a 10 year design life, load of 20psf fluid loading, and a max temperature of 120ºF. The composite repair was designed to share the load with the steel, where it is assumed that this average remaining wall thickness is 0.125” (3.175mm). One challenge during the application was limited space access. The ICR technician fabricated a custom roller with an extension that enabled the Technowrap 2K™ to be applied between the equipment and skid pan catch basin to overcome the cramped working area.
Results

  • The repair was engineered with a 10 year defined life
  • No hot work required, reducing safety risk
  • A cost-effective solution compared with welded replacement
  • Carried out with minimal POB requirements
