Internal and external protection of process vessels
Belzona elevated 60°C – 90°C (140°F – 194°F) and high temperature 90°C – 160°C (194°F – 320°F) linings can be spray or hand-applied and, once cured in service, form a barrier between the substrate and corrosive media, enabling the operator to extend the corrosion management timescales. As well as resisting erosion-corrosion, Belzona linings are designed to withstand vast pressure and temperature fluctuations, including steam-out and explosive decompression. A complete corrosion solution includes small bore nozzle and flange face protection, using materials such as Belzona 1511 (Super HT-Metal) and Belzona 1391T, in order to fully isolate the substrate from the corrosive environment.
Pipework repair and protection
Thin-wall and through-wall damage can be repaired with the use of Belzona metal repair composites. Pipe wraps, plate bonding and pit filling can prolong the life of assets.
Repairs to pressurised and safety critical systems can be completed with Belzona SuperWrap II in accordance with the ISO 24817 and ASME PCC-2 standards. This wrap is one of the strongest composite wrap systems on the market and its tensile shear adhesion actually increases in service. It is suitable for pipes and vessels, including complex geometries and can repair thin- and through-wall defects, eliminating the need for traditional cut and weld hot work. The system is suitable for use in a range of climates and service temperatures (up to 150°C (302°F).
Belzona 3411 (Encapsulating Membrane) can be used to prevent flange corrosion by sealing the flanged connection from the environment. The system can be easily peeled back for inspection and resealed to reinstate protection.
Corrosion under insulation (CUI) can be repaired using surface-tolerant heat-activated polymeric materials and further corrosion prevented by encapsulating the insulation with a microporous Belzona 3211 (Lagseal) system.
Belzona provides cold bonding solutions as an alternative to welding for installation and maintenance of assets such as decks, tanks, pipes and fittings, which can be safely and easily carried out in situ. Deck equipment, framework and supports can be bonded permanently and safely. Belzona cold bonding is equally effective at the fabrication stage, during turnarounds or whilst the platform is in operation. Corroded equipment and structures can be repaired in situ with Belzona’s pioneering injection bonding technology. This technique has been successfully utilised for deck renovation and other structural integrity repairs.
Splash zone repair and protection
Corrosion resistant repair composites and coatings can be used to repair rubber sheath and pitting corrosion damage and will ensure long-term erosion and corrosion protection of risers. Belzona’s flexible sealing solutions such as Belzona 2111 (D&A Hi-Build Elastomer) can be used for repairs, creation of fillets and rubber rebonding. Belzona’s surface-tolerant protective coatings such as Belzona 5831 (ST-Barrier) can be applied in situ on splash zones and below the waterline.
Storage tank and secondary containment area repair and protection
Belzona provides solutions for damaged storage tanks including emergency leak sealing and cold plate bonding, using fast-curing epoxy materials that will eliminate the need for hot work, therefore reducing health and safety concerns. Tank bases can be sealed with our solvent-free coatings such as Belzona 3111 (Flexible Membrane) that will allow trapped moisture to escape whilst preventing water ingress at the tank base for long-term protection.
Concrete floors and walls of secondary containment can be repaired and protected using the range of Belzona concrete repair composites and coatings, which will greatly reduce downtime. Concrete repair materials such as Belzona 4111 (Magma-Quartz) are ideal for the repair and resurfacing of damaged secondary containment areas. Epoxy coatings such as Belzona 4361 and Belzona 4341 (Magma CR4) are designed to provide long-term chemical protection against a wide range of substances including acids and alkalis even at high temperatures.
Our metal repair composites, high temperature coatings and linings are suitable for other areas, including:
