System DBPP 4.b—Enhanced corrosion/insulation protection with shrink sleeve

This system enhances System DBPP 4.a with the added durability and protection of an outer Canusa shrink sleeve. This provides superior corrosion protection above ground, but is especially designed to protect buried pipe. This system is designed for pipelines with operating temperatures ranging from -45°C (-49° F) up to 95°C (203° F) normal service and up 110°C (230° F) intermittently.

  • Surface prep. SSPC SP10 near white (NACE 3)
  • Applied direct to steel
  • Standard 20 – 25 mils DFT
  • Polyurethane injection moulded foam insulation/rock shield (minimum 3 lb. density) to guarantee a completely sealed final product (thicknesses ranging from 1" – 3" with custom sizing available)
  • Canusa shrink sleeve applied over injected insulation to Canusa specs
