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 helpsreduce downtime,minimise operational disruptionandextend 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.

Key Features and Benefits

• Fully Compliant Engineered Solution – Belzona SuperWrap designs and applications can be carried out in accordance with international composite repair standards ISO 24817 and ASME PCC-2 (Article 401).
• Quick Return to Service – The in-situ, wet-on-wet application procedure and fast cure help minimise downtime. Thin-wall repairs can be completed in service, without the need for shutdown.
• Extensive Damage Repair – Lightweight composite technology effectively repairs through-wall defects with minimal additional load, reducing installation complexity and eliminating the need for hot work.
• Strong, Durable and Long-Lasting Solution – High Young's modulus and strong adhesion help ensure long-term repair integrity and performance, particularly for through-wall defects. The system can remain maintenance-free for up to 20 years.
• Global Training and Technical Support – Fully validated training available at 19 global training centres ensures installers, supervisors and designers meet internationally recognised engineering standards.
