Belzona SuperWrap Composite repair system

Belzona SuperWrap

Based on epoxy resins and performance enhancing fillers in combination with high density treated glass fibre reinforcement, Belzona SuperWrap offers a long-term alternative to replacing defective steelwork. This cold cure solution has been developed as a compliant pipe wrap or patch repair to return strength to weakened or holed metallic surfaces and provides excellent corrosion protection and chemical resistance.

Belzona SuperWrap has been extensively tested at pressures in excess of 250 bar (3,625 Psi) and can be used in a large variety of environments, on almost any pipework geometry and over a wide range of temperatures.

The Belzona SuperWrap material has been prequalified to the international composite repair standards ASME PCC-2 Article 4.1 and ISO/TS 24817 and complies with US DOT regulations for "an engineered solution". It can be used where engineered calculations and documentation including quality control records are required.

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.
