Repair Composites and Coatings for the Petrochemical Industry

Belzona epoxy-based metal repair composites, coatings and linings for the repair and protection of equipment common in the petrochemical industry.

Repair Composites and Coatings for the Petrochemical Industry

The petrochemical industry is regularly faced with problems such as erosion, corrosion, chemical attack, wear, abrasion and mechanical damage which cause deterioration of infrastructure and equipment over time. Rather than replacing these assets, engineers and plant managers are using Belzona epoxy-based metal repair composites, high temperature coatings and linings for reliable, long lasting maintenance solutions.

Our solvent free materials offer solutions for the toughest environments and can be applied in-situ to reduce downtime and labour costs, eliminating the need to replace equipment.

Deterioration of pipework

Pipework can suffer from erosion and corrosion including corrosion under insulation (CUI), which can result in leaks and loss of containment. Epoxy coatings such as Belzona 5851 (HA-Barrier) can be applied on equipment at elevated temperatures to provide corrosion protection and prevent loss of wall thickness. Additionally, Belzona offers insulation protection for pipes and other insulated equipment using fire retardant Belzona 3211 (Lagseal) which is simple to apply and will resist water and UV radiation.

Pipe leaks can be sealed in-situ using Belzona metal repair composites such as Belzona 1221 (Super E-Metal) and Belzona 1111 (Super Metal). Alternatively, the ASME PCC2 Article 4.1 and ISO/TS 24817 compliant pipe wrap system, Belzona SuperWrap II, can be used to return strength to weakened or holed pipes and provide excellent corrosion protection and chemical resistance.

Deteriorated pipe supports due to corrosion, sliding wear and galvanic effects can lead to extended forced shutdowns. Belzona's cold-applied epoxy composite repair material can be used to bond new pipe supports, eliminating the requirement for welding.

Corrosion protection process vessels

Absorber towers and strippers are subject to a number of corrosion problems during their service life. Epoxies are proven to be the optimum lining solution for process vessels as they provide excellent chemical, erosion and temperature resistance.

Belzona high temperature epoxy linings including Belzona 1391 (Ceramic HT) have a proven track record in aggressive operating conditions and are resistant to problems associated with MEA, MDEA, sulfanol and other stripping agents.

Additionally, our solvent free epoxy coatings have resistance to explosive decompression, steaming out, bacterial and chemical attack. The unique binary curing mechanism allows Belzona coatings to cure in service, thus enabling you to get equipment back into service with the minimum of downtime.

Storage tank and secondary containment area repair and protection

Belzona provides solutions for storage tanks damaged as a result of deterioration, corrosion and adverse weather conditions, including emergency leak sealing and cold metal bonding. Our fast cure epoxy repair materials such as Belzona 1221 (Super E-Metal) and Belzona 1111 (Super Metal) will eliminate the need for hot work, therefore reducing health and safety concerns.

Tank bases can be sealed with our safe and easy to apply flexible membranes 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.

Containment areas and support structures can be repaired and protected against chemical attack using Belzona's range of conrete repair composites and coatings. Belzona 4111 (Magma-Quartz) and Belzona 4131 (Magma-Screed) are ideal for the repair and resurfacing of damaged secondary containment areas. Epoxy coatings such as Belzona 4311 (Magma CR1) 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 and concentrations.

Repair composites and coatings for heat exchangers

Belzona provides a variety of solvent free metal repair composites and epoxy coatings for repair and protection of heat exchangers damaged by erosion and corrosion on areas such as tube sheets, water boxes, division bars and end covers.

Our cold curing epoxy products allow for rapid, in-situ application minimising downtime whilst providing long-term erosion and corrosion protection. Belzona materials are excellent electrical insulators, which enables them to prevent galvanic corrosion by isolating the dissimilar metals used in heat exchangers.

Our repair composites, high temperature coatings and linings are suitable for other areas including:

  • Pump repair and protection
  • Insulation protection
  • Conveyor belts, valves and other rubber repairs
  • Protective coatings and repair compounds for floors
  • Anti-seize for mating compounds
