Industry operating characteristics
Variable chemical media, splash, vapour, wet service and process heat require substrate-specific system selection.
Industry applications
Chemical & Fertilizer
Barrier and thermal protection for process vessels, scrubbers, tanks, pipework and wastewater assets exposed to identified media.
Typical process and equipment systems
Reaction, absorption, neutralisation, storage, transfer and wastewater treatment expose steel and concrete differently.
Typical equipment
Operating environment and conditions
Environmental exposure
Acids, alkalis, salts and process liquids
Corrosive mist and splash
Wet-dry and temperature changes
Operating conditions
Continuous process exposure
Cleaning and maintenance contact
Steel and concrete substrates
Why the problems form
Media penetrate at pores, cracks, joints and film defects; temperature, concentration and wet-dry cycling change the attack mechanism.
Chemical-medium attack
Typical equipmentProcess vessel · tank · scrubber
Identified acids, alkalis, salts or process liquids can penetrate incompatible or discontinuous films.
Softening, discoloration, loss of adhesion and substrate attack can develop around defects.
View solutionCondensation and under-film corrosion
Typical equipmentPipeline · steel structure · ventilation duct
Moisture collects at cold spots, welds, supports and poorly drained details.
Blistering, pitting and hidden corrosion can spread beyond the visible defect.
View solutionHigh-temperature oxidation
Typical equipmentReactor exterior · hot line · dryer
Heat, cycling and the local gas atmosphere accelerate oxidation at exposed surfaces and joints.
Scale, cracking and local loss of the protective barrier can increase maintenance exposure.
View solutionHeat loss and hot surfaces
Typical equipmentReactor · process line · vessel
Exposed surfaces, damaged insulation, supports and complex geometry create thermal paths.
Uneven surface temperature and heat loss can affect access, process stability and energy use.

What information is needed to review protection in Chemical & Fertilizer?
Provide the equipment location, substrate, medium, operating state, visible chemical-medium attack signs, access and maintenance constraints. The review must begin with the actual service condition.
Which Chemical & Fertilizer equipment should be inspected first?
Prioritise assets such as Storage tank · Pipeline · Scrubber · Process vessel where exposure is concentrated, coating condition is changing or access is only available during shutdown.
Can an old coating be overcoated in Chemical & Fertilizer service?
Only after adhesion, contamination, moisture, defects and compatibility are assessed. Loose or chemically affected layers around chemical-medium attack zones must not be buried.
How should combined corrosion and wear be handled in Chemical & Fertilizer?
Map where each mechanism dominates, especially around chemical-medium attack areas, then define preparation and a compatible layered system for each zone.
How is application quality checked for Chemical & Fertilizer equipment?
Use traceable preparation records, environmental checks, coverage and defect inspection, confirmed hold points and the protection objective: identify the actual medium and exposure.
What should a maintenance plan for Chemical & Fertilizer include?
Record repeatable inspection locations on Storage tank · Pipeline · Scrubber · Process vessel, changes at welds, edges and repairs, and correct local damage before it spreads beneath the surrounding system.
