Process Vessel Repair and Linings
ASTM-tested coatings that outperform industrial standards — applied cold, in place, with local expertise you can trust.
When Standard Coatings Fall Short
Process vessels face some of the harshest conditions in any industrial facility — aggressive chemicals, elevated temperatures, abrasive slurries, and constant thermal cycling. Standard industrial coatings are designed for general corrosion protection, not the specialized demands of chemical processing, pulp and paper, food and beverage, or power generation environments.
Belzona process vessel solutions are engineered for performance and tested to prove it. While many coatings claim chemical resistance, Belzona products are tested to ASTM standards across hundreds of chemical combinations, temperatures, and exposure durations — and we publish the results.
Cold-applied and in-situ curing means no hot work permits, no vessel removal, and faster return to service. And with over 100 years of combined experience in the Pacific Northwest — including NACE Level 1-3 and SSPC certified professionals who have worked these industries for decades — you get local expertise that understands your facility, your regulations, and your operational constraints.
Pacific Northwest Expertise Since Day One
Our team brings over 100 years of combined experience — all of it in Washington, Oregon, Alaska, and Northern Idaho. We hold NACE Level 1-3 certifications and SSPC credentials, but more importantly, we've spent decades working inside the refineries, pulp mills, power plants, and processing facilities of the Pacific Northwest. We know what works in your environment, we understand your regulatory landscape, and we're here when you need us — not across the country waiting for a flight.
Tested Performance, Not Marketing Claims
Most industrial coatings publish basic adhesion and hardness. Belzona publishes complete ASTM test results across dozens of performance categories — so you can verify before you specify.

Applications
Mixing Tanks
Protect against chemical attack, rebuild eroded walls, and line tanks for long-term corrosion resistance. Products selected based on your specific chemical environment.
Reactor Vessels
High-temperature chemical immersion protection for reactors handling aggressive chemistry. Belzona 1391T provides continuous service up to 120°C with steaming-out capability.
Pressure Vessels
Rebuild corroded shell sections, repair nozzle connections, and protect internal surfaces — all without hot work permits or vessel removal from service.
Agitator Shafts
Rebuild worn shafts to original dimensions, protect sealing surfaces, and apply low-friction coatings for reduced wear. Belzona 1341 provides excellent release properties.
Manways and Nozzles
Repair and protect high-wear entry points, rebuild corroded flanges, and seal leaking connections without welding or hot work.

Frequently Asked Questions
How do I know which Belzona product to use?
Product selection depends on your chemical environment, operating temperature, and type of damage. Contact us with your specific conditions — we'll review Belzona's chemical resistance data and recommend the right system.
Can you repair vessels without removing them from service?
Yes. Belzona products are cold-applied and cure at ambient temperature. Most repairs can be completed during scheduled maintenance windows without removing equipment or requiring hot work permits.
What surface preparation is required?
Proper surface preparation is critical. Depending on the product, this typically involves solvent degreasing, abrasive blasting or mechanical preparation to white metal or near-white metal, and application of Belzona conditioner. We provide detailed specs and on-site support.
How long do repairs last?
With proper surface preparation and product selection, Belzona repairs routinely last 10-20+ years. We have documented case studies throughout the Pacific Northwest with repairs still performing after decades of service.
Are Belzona products FDA compliant?
Several Belzona products are FDA compliant for incidental food contact. For food and beverage applications, contact us to discuss your specific requirements and we'll recommend compliant solutions.
Do you provide on-site application support?
Yes. Our NACE-certified team provides training, application guidance, and on-site supervision throughout Washington, Oregon, Alaska, and Northern Idaho. We've worked in facilities across the region and understand local requirements.
How quickly can I get product?
We stock common products locally and can typically ship within 24-48 hours for standard orders. For emergency repairs, same-day delivery may be available depending on location. Call us directly for urgent needs.
Where can I find chemical resistance data?
Belzona publishes comprehensive chemical resistance charts for each product on their website. We can also provide specific immersion test results for your chemicals and help interpret the data for your application.
