Chemcote Steel Manufacturing Coating Solutions
Advanced Anti-Corrosion, Extreme Temperature and Structural Life Extension Coatings for Steel Manufacturing Infrastructure
Protecting steel manufacturing, blast furnace and coking plant infrastructure requires specialised engineering coating systems capable of withstanding extreme thermal shock, aggressive chemical exposure, severe mechanical wear and continuous process water immersion. Critical plant assets including preheaters, demisters, gas scrubbing pipework, hot car structures, steel clarifiers and supporting structural steelwork suffer from rapid pitting corrosion, microbiologically influenced corrosion (MIC), thermal degradation and wall thinning. Without advanced surface protection, these harsh operating environments lead to catastrophic pipe perforations, unexpected plant outages and escalating capital replacement expenditure.
Chemcote provides industry-leading, Australian-owned protective coating applications, NACE and ACA certified inspections, design specifications and asset refurbishment services across Australia. Servicing major steel producers including BlueScope Steel, Chemcote deploys high-performance vinyl ester glassflakes, high-temperature novolac epoxies, basalt fibre composites and surface-tolerant epoxies to extend asset service life while ensuring operational reliability and environmental compliance.
The Steel Manufacturing Corrosion Challenge
Operating blast furnaces, coke ovens and steel processing mills presents severe thermal, chemical and mechanical degradation hurdles:
Extreme Thermal Cycling & Thermal Shock: Hot car structures transporting 1,000°C coking coal to quenching stations endure extreme thermal shock when dumped with 80 tonnes of recirculated water, causing standard coatings to fail in 2 to 8 weeks.
Severe Gas & Process Water Attack: Blast furnace gas, sulphur, zinc deposits and recirculated process water cause aggressive pitting up to 10mm deep and MIC inside demisters, scrubbers and preheaters.
Premature Failure of Stainless Steel Piping: Austenitic and 316L stainless steel pipes suffer rapid pitting corrosion and crevice attack in salt water or chemical lines, causing total plant shutdowns within months of installation.
Strict Shutdown Schedules & Hot Working Limits: Plant maintenance must proceed under tight turnaround windows (often 50 to 76 hours) where dry grit blasting, dust generation and solvent fumes are strictly restricted.
Why Chemcote? The Technology Advantage
Chemcote shifts the maintenance paradigm by deploying surface-tolerant, high-temperature novolac epoxies, glassflake-filled vinyl esters and basalt fibre composite wraps engineered for mechanically prepared or hydro-blasted steel. Our specialised technologies eliminate the need for costly abrasive blasting containment, allowing rapid return to service without disrupting parallel site operations.

Key Technical Benefits
1. Thermal Shock & High-Temperature Armour
Our high-temperature novolac epoxy systems (Epo-Chem RE 500P & RW 500) withstand extreme thermal shock and cycling from 1,000°C coking coal transport to 80°C water quenching, providing years of continuous protection.
2. Impermeable Glassflake Corrosion Barriers
Our vinyl ester glassflake series (Chem-tect RB 300 / RB 332) features an exceptionally low moisture vapour transmission (MVT) rate, halting deep pitting corrosion, MIC and chemical attack across a pH range of 0 to 13.
3. Composite Reinforcement & Stainless Steel Repair
By combining low-MVT vinyl esters with woven basalt fibre composite wraps and Kevlar laminates, Chemcote reprofiles and structurally reinforces pitted 316L stainless steel pipes and centrifugal pump vanes without expensive piping replacement.
4. Fast Turnaround & Immersed-Rated Steel Protection
Using high-pressure water jetting (up to 40,000 psi) and surface-tolerant epoxies (Epo-Chem RS 500P & RA 500M), we convert atmospheric structural steel exposed to active leaks into heavy-duty immersed assets with expected service lives of 20+ years.
Specialised Steel Manufacturing Solutions
1. Preheater, Demister and Gas Scrubbing Equipment
Internal re-lining of preheaters, blast furnace demisters, fume suppression pipes and gas cleaning scrubbers using Chem-tect RB 332 glassflake vinyl ester, eliminating deep pitting and MIC during short 50 to 72-hour plant shutdowns.
2. Hot Car Coking Coal Wagon Refurbishment
Protecting mild steel hot car structures exposed to 1,000°C coking coal and 80 tonnes of quenching water. Applying high-temperature surface-tolerant novolac epoxies over mechanically prepped steel to prevent severe structural degradation.
3. Stainless Steel Pipework & Centrifugal Pump Armouring
Repairing perforated 316L stainless steel elbows, condenser mains and split-case centrifugal pumps using Kevlar laminates, basalt fibre composite wraps and Chem-tect RB 364 linings to halt crevice and pitting corrosion.
4. Steel Clarifier, FRP Chemical Tanker & Structural Steel Life Extension
Full restoration of steel clarifiers, chemical transport tankers and critical supporting pipe bridges exposed to steam and salt water leaks using Epo-Chem RS 500P MIO primer and RA 500M glassflake topcoats.

Frequently Asked Questions
How do Chemcote coatings survive extreme thermal shock on coking hot cars?
We deploy specialised high-temperature novolac epoxy systems (Epo-Chem RE 500P primer and RW 500 glassflake topcoat). Formulated specifically for aggressive thermocycling, this system withstands the rapid transition from 1,000°C coking coal transport to 80°C recirculated water quenching without cracking or delaminating.
Can Chemcote repair perforated 316L stainless steel pipes without fabricating new sections?
Yes. We re-profile deep pitting perforations using composite repair techniques, apply a low-MVT vinyl ester glassflake lining (Chem-tect RB 364) to the interior and wrap the exterior with a woven basalt fibre composite matting. This restores structural integrity and prevents crevice attack at a fraction of the cost of new piping.
How does Chemcote complete major vessel re-linings within short 50 to 72-hour shutdowns?
Our fast-curing vinyl ester (Chem-tect RB 332) and surface-tolerant epoxy systems require minimal surface cure delays. Because these coatings can be applied over mechanically prepped steel or UHP water-blasted surfaces, we eliminate lengthy abrasive blasting setups and return critical assets like demisters and clarifiers to service on time.
What surface preparation methods are used when dry grit blasting is prohibited in active mills?
When dry abrasive blasting is prohibited due to dust contamination or nearby trades, Chemcote utilises mechanical surface preparation tools (scabblers, needle guns, bristle blasters) or ultra-high pressure water jetting up to 40,000 psi. Our surface-tolerant primers (Epo-Chem RS 500P) bond directly to damp, mechanically prepared steel.
