Chemcote Oil and Gas Coating Solutions
Advanced Anti-Corrosion, Extreme Temperature and Asset Integrity Coatings for Onshore & Offshore Infrastructure
Protecting onshore and offshore oil and gas assets requires specialised engineering coating systems capable of withstanding extreme environmental pressures, aggressive chemical exposure, high humidity and continuous thermal cycling. Critical infrastructure including offshore rig decks, caissons, produced water separators, storage tanks and vacuum pumps face rapid pitting, microbiologically influenced corrosion (MIC), osmotic blistering and crevice attack. Without advanced surface protection, these harsh operating conditions lead to structural metal loss, potential vessel perforations, environmental risks and costly unscheduled shutdowns.
Chemcote provides Australian-owned protective coating applications, NACE and ACA certified inspections, design specifications and asset refurbishment services across Australia. Servicing leading energy operators including Mobil, Viva and Caltex, Chemcote deploys high-performance glassflake vinyl esters, high-temperature novolacs and surface-tolerant epoxies to extend asset service life while dramatically lowering ongoing maintenance and preservation expenditure.
The Oil & Gas Corrosion Challenge
Operating upstream, midstream and downstream oil and gas infrastructure presents severe degradation mechanisms:
High Humidity and Splash Zone Degradation: Offshore rig decks, risers and splash zones experience continuous marine exposure where conventional coatings quickly fail due to high humidity during application.
Elevated Temperatures and Thermal Cycling: External exhaust stacks, manifolds and process pipework operating at elevated temperatures (up to 105°C and higher) suffer from rapid atmospheric corrosion and CUI.
Osmotic Blistering and Pitting in Vessels: Produced water vessels, separators and de-aerators suffer internal osmotic blistering from corrosive cargo, leading to severe localised pitting rates of 2-3 mm per year.
Complex Asset Maintenance Under Hot Working Conditions: Offshore and refinery environments often require online maintenance where hot working, spark risks, dehumidification setups and plant outages are strictly prohibited.
Why Chemcote? The Technology Advantage
Chemcote shifts the maintenance paradigm by deploying moisture and surface-tolerant, solvent-free glassflake coatings engineered for hot, wet or corroded steel substrates. Our specialised technologies eliminate the need for costly dehumidification or plant shutdowns, providing long-term corrosion protection even under active operating conditions.

Key Technical Benefits
1. Extreme Temperature & Immersed Protection
Our high-temperature glassflake-filled novolac epoxies (Epo-Chem RW 500) and vinyl esters (Chem-tect RF 300 / 900 Series) withstand continuous immersion up to 180°C and dry surfaces up to 850°C.
2. Online Application & Hot Work Safety
Using wet and surface-tolerant coatings (Epo-Chem RL 500PF / RS 500P), Chemcote carries out spark-free external stack and pipe repairs while equipment remains online at operating temperatures up to 105°C.
3. Galvanic & Crevice Attack Prevention
Precision machining and rebated flange designs filled with Chem-tect RB 300 vinyl ester eliminate crevice corrosion at gasket faces while restoring pump rotors and barrels back to original manufacturer tolerances.
4. Fast Turnaround & Extended Warranty Protection
Fast-cure, glassflake-reinforced systems (Epo-Chem RA 564) remove the delay and cost of dehumidification in large storage tanks, delivering 10 to 15+ year performance warranties and returning critical vessels to production within days.
Specialised Oil and Gas Solutions
1. Offshore Rig Decks, Risers and Splash Zones
Applying moisture and surface-tolerant glassflake epoxies directly to wet, hydro-blasted rig decks and structural steelwork in high-humidity offshore environments, completely halting recurring corrosion cycles.
2. Produced Water Vessels, Separators and Process Tanks
Internal re-lining of pressure vessels using high-temperature novolac glassflake barriers (Epo-Chem RW 500) to eliminate osmotic blistering, pit-fill localised corrosion and prevent wall thinning.
3. Vacuum Pump and Rotating Equipment Refurbishment
Rebuilding corroded carbon steel vacuum pump barrels, rotors and end plates using Chem-tect RB 300. Post-machining to tight dimensional tolerances and dynamic balancing eliminates costly 20-week new equipment lead times.
4. Fuel Storage Tank Floor and Wall Protection
Applying glassflake-reinforced epoxy systems (RA 564) over 40m diameter oil storage tank floors and internal walls. Moisture tolerance eliminates dehumidification costs while delivering 15+ years of maintenance-free service.

Frequently Asked Questions
How does Chemcote apply coatings to high-temperature stacks without shutting down the plant?
We utilise specialised wet and surface-tolerant coating systems (Epo-Chem RL 500PF) combined with spark-free mechanical surface preparation. This allows our team to safely prepare and coat external stacks and hot pipework operating online at temperatures up to 105°C without requiring plant outages.
Can Chemcote rebuild severely corroded vacuum pumps back to original manufacturer tolerances?
Yes. We apply Chem-tect RB 300 glassflake vinyl ester up to 3000µm thick over corroded carbon steel components. The coating is then post-machined and dynamically balanced to exact manufacturer specifications, eliminating 20-week lead times for new pump replacements.
Why are Chemcote tank coatings more cost-effective for large oil storage tanks?
Traditional tank coatings require expensive, continuous dehumidification equipment to prevent flash rusting on blasted steel. Chemcote’s moisture-tolerant Epo-Chem RA 564 glassflake epoxy can be applied directly in humid conditions without dehumidification, reducing setup costs and providing over 15 years of corrosion protection.
How do Chemcote internal linings stop osmotic blistering in produced water vessels?
Osmotic blistering occurs when moisture penetrates standard coatings, causing localised corrosion pitting rates up to 3mm per year. We replace failed linings with high-temperature novolac glassflake epoxy (Epo-Chem RW 500), forming an impermeable barrier that prevents fluid migration and halts ongoing metal loss.
