Coating & Lining
Coating: Resistant film applied to the exterior of an asset. Not necessarily subject to immersion.
Lining: Resistant film applied to the interior of an asset. And subject to immersion in liquids, chemicals of food products.
- Pre-qualified for fitness in oil and gas service
- 2 color systems
- Phenol-formaldehyde Novolac resin-based two-component systems
- Thin coatings DTF < 40 mil & thick coating DTF > 40 mil

Type of Belzona Coatings Based on Intended Purpose
Environmental Protection
Coatings primarily used for protecting assets which are susceptible to environmental damage or deterioration (roofs, external concrete or steel wals, flanges, pipes, risers, buildings, etc)
CUI
Protection
Coatings primarily used for protecting assets which are susceptible to corrosion under insulation (insulated pipelines, piping, nozzles, tanks, vessels, heat exchangers etc)
Flooring
Coatings primarily used for protecting floors suffering from abrasion, impact, erosion, or lack of slip resistance (floors and stairs in foot and vehicular traffic areas, warehouses, parking areas, industrial facilities, helpads, etc)
Chemical Protection
Coatings primarily used for protecting assets which are susceptible to chemical attack (tanks and secondary containment areas, exterior metallic or concrete walls exposed to frequent or incidental chemical spillage, etc)
Environmental Protection
Repair of walls suffering from environmental damage
- spalled beams
- cracked or spalled concrete
- damaged columns
Repair of structures exposed to offshore chemical & marine environment
- platform risers and legs, deck, splash zone, topside living quarters, piping and accessories (flanges)
Repair of exterior structures exposed to inland oil refining and petrochemical areas
- piping and accessories, equipment walls and supports exposed to the environment
Repair of exterior structures in inland rural areas
- bridges, towers

Fixing Heat Exchangers Tube Sheets Using Belzona Technology
Chemical attack and corrosion was severely wearing the tube sheets of this heat exchanger.
A Belzona coating was chosen based on service and operating conditions.
Heat exchanger is isolated from adjacent equipment.
Tubes are sealed using corks before surface preparation commences to prevent blasting media from entering them and potentially wearing the internal wall.
Surface cleanliness as per SSPC SP10 (Near White Metal) with average 3 mil profile and no soluble ion contamination embedded into profile
Coating application can be carried out by hand (brush/roller) or airless spray
Corks are pushed inside the tubes and removed by compressed air

Nozzle Insert
How do We Ensure Vessel or Tank Full Protection?
Nozzles also need to be lined or the vessel will not be entirely protected
The Belzona Solution for Nozzle Protection
- Nozzle inserts can be pre-fabricated of fit-for-service paste grade Belzona materials
- Designed to the asset owner’s size requirements, but some restrictions based on best practices: diameters between 1 and 4 inches, minimum wall thickness of 120 mil, and length limited by manufacturing techniques
- Glued onto the nozzle inner wall with Belzona fluid-grade materials into the nozzle

Pipe Lining
Piping can be lined by spin spray for internal protection against erosion, corrosion, and chemical attack using fit-for-service coatings.
Inspection techniques are used to ensure holiday-free finishes.
Flange Protection Solution
- Quick and easy
- Suitable for any flange size
- Peelable and resealable
- U.V. resistant
- Acceptable for manual surface preparation
- Available in two colors
SF6-FIX Solution
Key Benefits of Belzona SF6-FIX:
- Can reduce leaks to undetectable levels
- Removable for joint access
- Excellent corrosion protection
- Rapid installation, short cure times
- Online application, minimum downtime
SF₆ is commonly used in medium and high voltage electrical equipment making it crucial to the efficient functioning of power grids. Despite its utility, SF₆ is incredibly detrimental to the planet with a warming potential.Most common causes of SF6 leaks include corrosion and mechanical damage.
Belzona SF6-FIX is an effective solution that can reduce SF₆ leaks to undetectable levels.
