Advanced Coating System HT-200 (ACS™)

HT200 is a flow assurance insulation system for ultra deepwater applications used for thermal management of subsea flowlines and risers. This product is designed to perform at the highest known service temperatures.

Layers

The insulation system is composed of three layers:

  1. An anti-corrosion coating layer (high temp FBE)
  2. A molded insulation layer
  3. A polypropylene topcoat for UV resistance and mechanical protection
