ACS™ HT-200 Insulation System

ACS™ HT-200 is used as thermal insulation for offshore pipelines. The product can be customized to meet specific project requirements such as offshore lay method and thermal requirements. The insulation system is composed of three layers:

  • Anti-corrosion coating layer which can be an FBE coating or a liquid epoxy/novolac coating selected to meet the temperature requirement
  • PN based insulation
  • Polypropylene topcoat for UV resistance and mechanical protection
