Protection Systems
System DBPP 3 - Corrosion/insulation protection with shrink sleeve
This system enhances DBPP2 with the added durability and protection of an outer Canusa shrink sleeve. Designed especially for buried pipe, it is an effective solution for pipelines with operating temperatures ranging from -34° C (-30° F) up to 85° C (185° F).
- Surface prep. SSPC SP6 commercial sandblast (NACE 3)
- Renwrap #327 high bond primer direct to steel
- Renwrap #303 13 mil yellow coating tape
- 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
System DBPP 4.a—Enhanced corrosion/insulation protection
The application of a dual component epoxy coating that is highly adhesive, provides permanent and fully-effective corrosion protection. In conjunction with our insulation/rock shield, this system supplies uninterrupted protection 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)
- Application of Renwrap #330 50 mil black outer tape wrap
