Belzona SuperWrap II

A new generation compliant composite repair system for restoring the strength of corroded, weakened and holed pipes and tank walls.  

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 PCC-2. 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:

  • 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
