Belzona SuperWrap

A compliant composite repair system for adding strength to damaged pipes and tanks.

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.
