Belzona SuperWrap II

Belzona SuperWrap II offers a new generation repair solution for corroded, weakened and holed pipe and tank walls, compliant to ISO24817 and ASME PCC2. It comprises a fluid grade resin system, a bespoke hybrid reinforcement sheet based on fibre glass and carbon fibre, as well as release film to consolidate and finish off the application.

The system is available in two different resin grades, Belzona 1981 and Belzona 1982, making it suitable for applications in various service temperatures (from 5°C/41°F to 80°C/176°F) as well as where either a short or long working life is required.

This composite repair system was engineered for pipe wrap and patch repair as an alternative to replacing defective metallic substrates, providing superior strength, corrosion and chemical resistance. Belzona SuperWrap II allows quick and easy repair of equipment within industries such as Oil and Gas, Power Generation and Marine.

Key benefits:

  • Compliant to ISO24817 and ASME PCC2 and applied by trained and validated personnel
  • Quick and easy to apply even under online conditions, ensuring rapid back to service time
  • Belzona paste grade is available for restoration of pitted surfaces prior to application of the compliant wrap system
  • Can be used in service temperatures ranging from 5°C (41°F) to 80°C (176°F)
  • Superior strength (high Young’s modulus),
  • Outstanding corrosion and chemical resistance
  • Thermal expansion coefficient similar to that of steel, reducing build-up of strain due to thermal cycling
  • Long working life of Belzona 1982 resin allows application in large volumes
  • Excellent bonding to carbon steel
  • Reduced health and safety risks as it is solvent free
  • Validated training available for Belzona SuperWrap II Designers, Supervisors and Installers, providing specific theoretical knowledge and practical skills

Applications for Belzona SuperWrap II include:

  • Composite pipe wrap system for the repair of complex geometries of pipes including bends, straights and tees
  • Compliant patch repair to large diameter pipes (over 600mm) and tank walls
  • Repair of through wall and thin wall defects on pipes and tank walls
