Denso Archco 466 Jeddah | Glass Flake Epoxy Tank & Pipe Lining

Chemical exposure and abrasive wear can damage steel tanks and pipework from the inside. A suitable lining creates a protective barrier between the steel and the service medium.

Nassguard supplies Denso Archco 466 in Jeddah for coating contractors, fabrication workshops, technicians and industrial maintenance teams. Denso Archco 466™ Epoxy Pipe Lining combines epoxy protection with glass flake reinforcement for chemically aggressive environments.

We supply projects across Saudi Arabia, including Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Is Denso Archco 466 Epoxy Pipe Lining?

Denso Archco 466™ is a two-part, glass flake epoxy phenolic-novolac coating for suitable steel tanks, vessels and pipe internals. It protects against corrosion, abrasion and chemical attack.

The lining offers resistance to compatible oil products, solvents, inorganic salts, water and certain acids. Its low permeability helps limit the passage of aggressive substances through the protective film.

Archco 466 also suits assessed applications involving crude oil, natural gas, wastewater and hydrogen sulphide. The exact chemical composition, concentration and temperature determine suitability for each installation.

Key Features of Denso Archco 466

The glass flake epoxy lining combines barrier protection with resistance to demanding industrial exposure.

• Glass flake reinforcement contributes to the lining’s low-permeability barrier.
• Strong adhesion helps the coating bond to correctly prepared steel.
• Chemical resistance supports compatible process and storage applications.
• Abrasion resistance helps protect surfaces against mechanical wear.
• Hydrocarbon resistance supports suitable oil-related service.
• H₂S resistance makes the lining relevant to assessed hydrogen sulphide exposure.
• Freshwater and saltwater immersion suitability supports compatible fluid-handling applications.
• Single-leg or plural-component spray application provides equipment options for coating work.

Applications of Archco 466 Glass Flake Epoxy Lining

Archco 466 suits internal steel protection projects where the coating matches the operating conditions and required chemical resistance.

• Coating contractors in Jeddah can specify it for suitable industrial tank and pipe lining projects.
• Fabrication workshops in Riyadh can apply it to suitable steel equipment within an approved coating programme.
• Maintenance teams in Dammam can consider it for internal corrosion protection during refurbishment.
• Process contractors in Jubail can assess it for compatible chemical tanks, vessels and pipelines.
• Engineering teams in Al Khobar can include it in suitable oil and gas equipment specifications.
• Specialist applicators can assess it for tubulars and downhole casing protection.
• Shutdown maintenance teams can plan compatible lining repairs alongside inspection work.

Steel Preparation and Glass Flake Lining Application

Correct preparation helps create continuous coverage, particularly around welds, edges and surface defects. Establish the preparation, application and curing requirements before starting work.

• Identify the service medium, including chemical concentration, operating temperature and cleaning conditions.
• Remove oil, grease and contamination before abrasive blasting.
• Smooth weld spatter, sharp edges and projections that could interrupt the protective film.
• Dry abrasive blast the steel to the cleanliness and profile required by the approved specification.
• Remove dust and abrasive residue before coating.
• Keep the steel dry and control condensation throughout application.
• Mix the components accurately and apply within the available pot life.
• Stripe-coat difficult details where the specification requires extra attention.
• Monitor film thickness during application and observe the recoat requirements.
• Complete the specified cure or post-cure before returning the equipment to service.

Certifications, Standards and Compliance

• ISO 9001:2015 – Quality Management applies to Denso’s manufacturing quality management system.
• ISO 14001:2015 – Environmental Management applies to Denso’s environmental management system.

Inspection and Maintenance of Lined Tanks and Pipes

Inspection confirms coating coverage and helps maintenance teams identify defects before service exposure causes further damage.

• Examine the finished lining for pinholes, cracks, runs, embedded debris and uneven areas.
• Measure dry film thickness with a calibrated gauge against the project acceptance limits.
• Perform holiday testing using the approved procedure and settings.
• Check welds, edges and connections where coating coverage needs closer examination.
• Prepare and repair defective areas with compatible materials.
• Reinspect repairs before accepting the completed lining.
• Record batch numbers, environmental conditions and inspection results for future maintenance.
• Review compatibility before service changes, especially when chemicals or temperatures change.

FAQs

1. What is Denso Archco 466 used for?

It protects suitable steel tank, vessel and pipe internals against corrosion, abrasion and chemical exposure.

2. Does Archco 466 contain glass flakes?

Yes, glass flake reinforcement forms part of its epoxy lining construction.

3. What mixing ratio does it require?

The standard formulation uses four parts base to one part hardener by volume.

4. Can it resist acids and hydrocarbons?

Yes, subject to confirmation of the chemical type, concentration, temperature and exposure conditions.

5. What thickness does the lining require?

A typical two-coat system achieves 762–1,016 microns total dry film thickness, subject to the project specification.

6. How does hot weather affect application?

Higher temperatures shorten the available working time, so crews must plan mixing and spraying around the actual material and site temperatures.

7. What should I send Nassguard for a quotation?

Provide the substrate, surface area, service medium, temperature, required thickness and coating specification.
