Tank & Process Vessel Internal Lining Services

Reduce downtime, extend asset service life and avoid replacement costs

Banks Industrial provides tank coating and process vessel internal lining services to shield valuable assets against chemical attack, abrasive solids, continuous immersion, elevated temperature and high-pressure operating environments. Application and maintenance of protective coatings will prevent metal loss and reduce risk of forced shutdown with costly downtime. We use a range of proven Belzona epoxy coatings backed by comprehensive testing and extensive historical data from actual applications. This allows selection of a fit for purpose solution matched to your operating environment. Our start-to-finish service includes site evaluation, surface prep, competent application and ongoing testing to verify condition of internal linings. We also repair holed conditions, cracked weld seams and areas of severe metal loss. Our epoxy linings are fast curing and applied in place for speedy return to service. In many cases we can save tanks that might otherwise need demo and replacement.

Benefits:

  • Reduce downtime with rapid application and fast curing capability
  • Provide long-term protection against corrosion, erosion and chemical attack
  • Excellent chemical resistance against a wide range of acids, alkalis and hydrocarbons
  • Create a durable barrier for tanks and process vessels operating under continuous immersion including those at elevated temperature
  • Stands up to steam-out, process upsets and explosive decompression
  • NSF ANSI 61 approved coatings suitable for potable water contact
  • Applied by brush or spray for large surface areas – faster application with less downtime
  • Cold applied, rapid curing at room temperature – no hot work needed
  • VOC and solvent-free materials lower health and safety risks in confined spaces

Applications:

  • Food & Beverage: tanks and silos requiring hygienic environment for drinking water and food contact
  • Pharma: settlement tanks, mixing tanks
  • Water / Wastewater: mixers, clarifiers, settlement tanks, aeration channels, buffer tanks
  • Facilities: hot water tanks, fire water tanks, TES tanks
  • Oil, Gas & Chemical: storage tanks and process vessels subject to aggressive operation at high temperature and pressure, handling amines, liquid hydrocarbons, gas and process chemicals
  • Patch repair for existing coatings such as glass flake and ebonite is possible

Need Internal Tank Coating?

Problem: Possibility of forced shutdown due to tank minimum wall thickness from corrosion

Over time, corrosion prevention methods such as protective linings, passivation, cathodic coatings and claddings will deteriorate. Chemical exposure, abrasion, immersion, elevated temperature, high-pressure, or combination thereof will eventually break through to the carbon steel substrate. The result is corrosion and metal loss damage to your asset. Sooner or later the deterioration will force a shutdown due to potential leaks and loss of containment. Unfortunately, internal lining repair or replacement is difficult considering the high cost of downtime, lost production and restart. Potential safety issues and environmental contamination further complicate this challenging situation.

Solution: Rapid rebuild of metal loss and application of tank lining to shorten downtime and extend service life

Whether planned or forced shutdown, application of an appropriate epoxy tank lining presents an effective option to minimize downtime and give your assets lasting protection. Applications are done in place and typically cure within 24 to 48 hours. This is much faster than the rebuild of process vessels or components using metal clads or increased metallurgy that take weeks or months. The time savings gained from epoxy tank lining often result in significant cost savings during an unplanned stoppage.

There are two important factors needed to make an epoxy lining work:

  1. Selection of a coating that is fit for purpose
  2. Competent prep and application

Coatings must be suitable for the intended operating conditions and applied correctly with best practices. Anything less will lead to premature lining failure. However, when properly selected and applied, epoxy tank linings are robust – even in process vessels where elevated temperature, high-pressure, steam-out cleaning and explosive decompression are brutal.

Banks Industrial uses durable Belzona epoxy tank linings backed by extensive testing data with confirmed field results. This enables us to find and recommend a solution that will suit your exact requirements and provide long-term protection. We handle all phases of application including blasting, rebuild of metal loss and coating application. After work is complete, we measure wall thickness as the basis for ongoing testing. This allows future verification of coating performance in an otherwise hidden area. You will be able to estimate coating service life and plan maintenance accordingly to avoid forced shutdowns.

Belzona internal linings are easily patch repaired or partially recoated. It is not necessary to replace the entire lining should damage occur. This simplifies maintenance and saves you money by further increasing service life.

Tank Lining Example

The tank shown above is part of a water remediation system at a superfund cleanup site in NJ. Interior corrosion was blasted to white metal in a climate-controlled enclosure, then lined with a chemical resistant epoxy coating suitable for continuous immersion. The tank exterior also received a barrier coating to protect against weather and UV wear.
