Belzona SuperWrap

Engineered composite repair systems designed to restore strength and maintain asset integrity in weakened, holed and corroded pipes and tanks.

Belzona SuperWrap

 

Based on high-performance epoxy resins combined with bespoke glass fibre or carbon/glass fibre hybrid reinforcement, Belzona SuperWrap offers a long-term alternative to replacing defective steelwork. This cold-cure composite pipe repair system restores strength to weakened or holed metallic substrates, helping to maintain asset integrity and provide long-term corrosion protection for pipework, pipelines and process vessels in safety-critical and pressurised applications.

By eliminating the need for traditional cut-and-weld repairs and costly asset replacement, Belzona SuperWrap helps reduce downtime, minimise operational disruption and extend the service life of existing infrastructure. Its engineered composite repair approach provides a durable, standards-compliant solution that can be tailored to individual operating conditions, helping customers maintain asset integrity while reducing maintenance costs and health and safety risks.

The Belzona SuperWrap system comprises four specialised systems, each designed for different application temperatures and service conditions. The range combines a choice of resin systems with a bespoke reinforcement, providing flexible composite pipe wrapping solutions for a variety of operating environments. These include a carbon/glass fibre hybrid reinforcement sheet for Belzona 1981 (WG-Wrap), Belzona 1982 (SG-Wrap), Belzona 1983 (HT-Wrap) and Belzona 1984 (ST-Wrap).

The Belzona SuperWrap system comprises five specialised systems, each designed for different application temperatures and service conditions. The range combines a choice of resin systems with two types of bespoke reinforcement, providing flexible composite pipe wrapping solutions for a variety of operating environments. These include a heavy-duty glass fibre sheet for Belzona 1972 (XL-Wrap) and a carbon/glass fibre hybrid reinforcement sheet for Belzona 1981 (WG-Wrap), Belzona 1982 (SG-Wrap), Belzona 1983 (HT-Wrap) and Belzona 1984 (ST-Wrap).

Each system is engineered to address the specific requirements of a broad range of industrial maintenance applications.

  • Belzona 1972 (XL-Wrap): Combines a high-thickness, heavy-duty glass fibre reinforcement sheet with a long-working-life resin. Ideally suited to large-scale applications, this system helps minimise the number of wraps required.
  • Belzona 1981 (WG-Wrap): Specifically formulated for cooler ambient temperatures and winter climates, providing reliable application and performance in low-temperature conditions.
  • Belzona 1982 (SG-Wrap): Optimised for higher ambient temperatures and summer climates, providing seamless application and reliable performance in warmer conditions.
  • Belzona 1983 (HT-Wrap): Designed for high-temperature service conditions, providing reliable performance at elevated operating temperatures, with compliance up to 150°C (302°F).
  • Belzona 1984 (ST-Wrap): Combines tolerance to surface preparation and water contamination with underwater application capability, making it ideally suited to demanding wet or submerged applications.

Belzona SuperWrap offers flexibility through a choice of specialised resins, reinforcement options and a range of thicknesses and widths, making it suitable for pipe wrap repair applications, from small, complex geometries to large-scale applications.

What is ISO 24817 testing?

ISO 24817 testing refers to the standardised qualification and performance testing of composite repair systems for metallic pipes and pipelines suffering from external corrosion or mechanical damage. This standard ensures that the repair method is structurally sound, long-lasting, and safe under defined pressure and temperature conditions.

Belzona SuperWrap has been tested and fully qualified to ISO 24817, demonstrating that it can restore or maintain the structural integrity of pipework in line with strict industry requirements for both design and application.

Are composite wraps compliant with ISO or ASME standards?

Yes, Belzona SuperWrap is fully compliant with both:

  • ISO 24817 (for composite repairs of metallic pipework)
  • ASME PCC-2 Article 4.1 (which governs non-metallic composite repair systems)

This compliance assures asset owners that Belzona SuperWrap meets globally recognised standards for performance, reliability, and safety, including under high-pressure, high-temperature, and hazardous service conditions.

What is the purpose of a pipe wrap?

The purpose of a pipe wrap like Belzona SuperWrap is to:

  • Restore structural integrity to damaged, corroded, or leaking pipes
  • Extend the service life of pipelines without the need for shutdown or replacement
  • Contain pressure and reinforce weakened areas
  • Provide a non-intrusive, cold-applied repair that avoids hot work

It's commonly used in oil & gas, petrochemical, marine, and utilities where traditional welding or replacement may not be feasible or safe.

What is a composite pipe repair system?

A composite pipe repair system is a solution that uses high-performance composite materials typically a combination of a reinforcement fabric (like carbon or glass fiber) and a polymeric resin to reinforce or restore pipework affected by corrosion, erosion, or mechanical damage.

Belzona SuperWrap is an engineered composite system that:

  • Is custom designed for each application based on pressure, temperature, and pipe geometry
  • Provides structural reinforcement and pressure containment
  • Offers a cold-applied, rapid-curing alternative to cutting and welding
What material is used for pipeline wrapping?

Belzona SuperWrap uses a high-strength composite system composed of:

  • Reinforcement fabric: Typically carbon fibre (for high-strength, high-performance needs) or glass fibre (for more general applications)
  • Epoxy resin: A specially formulated Belzona epoxy resin that bonds to the substrate and encapsulates the fibres
  • Release film: Used during the application process to ensure proper compaction and cure

The materials are selected and combined according to the specific design requirements of the repair (e.g., pipe diameter, pressure rating, environmental exposure).

Can composite wraps be used for high-pressure pipe repairs?

Belzona SuperWrap is specifically engineered for high-pressure applications. It can be designed to handle:

  • Both through-wall and non-through-wall defects
  • Live repairs, meaning pipework can remain in service during application

The system is backed by full engineering calculations and third-party testing, providing assurance for use in critical service lines such as hydrocarbons, chemicals, steam, and water.
