Industrial tank and vessel lining
Storage tanks, process vessels, retention basins and separators suffer chemical attack, under-product corrosion, permanent immersion and fill-empty cycles. Induscoat applies novolac epoxy, vinyl ester and polyurethane internal lining systems certified for immersion — NSF/ANSI 61 compliant for potable water and API 653 compliant for tanks.
The challenge: internal corrosion and product contamination
An unlined tank — or one whose lining has reached end of life — releases rust particles into the stored product, lets walls perforate and can cause a catastrophic leak. Internal corrosion of a potable-water tank risks bacterial contamination; of an acid tank risks rupture. Proper tank rehab requires good surface preparation and the right lining system — selected by fluid, temperature and immersion duration.
The solution: immersion-certified lining systems
Induscoat applies multi-coat internal lining systems in novolac epoxy, vinyl ester and polyurethane formulated for permanent immersion and chemical attack. Each project starts with a substrate condition inspection, followed by SSPC-SP10 near-white grit blasting, airless application in controlled DFT layers, and final thickness and adhesion testing. NSF/ANSI 61 (potable water) and API 653 certifications available.
Inspection of substrate condition, stored fluid and service temperature
SSPC-SP10 near-white blasting + anchor profile verification
Multi-coat airless application with wet and dry DFT control
Adhesion testing (ASTM D4541) + holiday test + QA/QC report
Benefits of professional tank lining
- Tank service life extended by 15 to 25 years
- Eliminates product contamination by rust particles
- Broad chemical resistance: acids, bases, hydrocarbons, potable water
- NSF/ANSI 61 potable water certification available
- API 653 compliance for storage tanks
- Reduced frequency of inspections and rehabs
Systems we apply
Induscoat selects the lining system based on your fluid (water, acid, hydrocarbon, slurry), temperature and immersion duration. We apply novolac epoxies and vinyl esters for immersion and high temperature, high-performance polymers and our own Induscoat formulations for Canada's most demanding services.

Frequently asked questions
How long does a tank lining last?+
A properly applied lining system after SSPC-SP10 blasting typically delivers 15 to 25 years of service depending on stored fluid, temperature and cycle frequency. We provide a recommended re-inspection plan with every project.
Does the tank need to be emptied for lining?+
Yes, internal lining requires an emptied, cleaned, degassed and isolated tank. Project duration depends on tank size and condition — allow 1 to 3 weeks for a typical storage tank. We schedule the work around your shutdown windows.
Are your linings certified for potable water?+
Yes, we apply lining systems certified to NSF/ANSI 61 for potable water contact. These systems are used for municipal reservoirs, cooling towers and potable water distribution systems in Canada.
What tank types do you line?+
Atmospheric storage tanks (API 650), pressure vessels, process tanks, retention basins, separators, cooling towers, road and rail tank cars. In carbon steel, stainless, concrete or composite.

Process vessel corrosion protection: internal linings and repair for reactors, columns and pressure vessels
Reactors, columns, separators and pressure vessels corrode in ways a storage tank does not: process chemistry, deposits, liquid-vapour interfaces and acid condensates. This guide covers the usual mechanisms, the protection options from alloy to internal lining, local pitting repair, the regulatory frame around a pressure boundary and how linings are inspected during a shutdown.
10 minIndustrial tank coating: how to choose the internal lining for the product you store
The right tank lining is decided by the service, not by the product catalogue. This guide walks through the selection criteria (stored product, temperature, vacuum, abrasion, cleaning, potable water and food contact), compares the main lining families, and explains how resistance charts, immersion tests and weld details turn a shortlist into a specification.
10 minApplying epoxy coatings in cold weather: what changes below 10 °C during a winter shutdown
Most industrial epoxies are formulated for application at 10 °C or above. In Quebec and Ontario, the shutdown window that matters most runs from November to January, when unheated tanks, pipe racks and containment areas sit well below that. This guide explains what actually goes wrong when epoxy is applied cold, how to measure the four numbers that decide whether a coating will cure, and which combination of low-temperature formulation, heating and dehumidification makes a winter lining job succeed.
8 minTank internal lining: fitting the job inside the shutdown window
An internal tank lining rarely fails because of the product. It fails because the shutdown window was planned around application time, forgetting the blasting, the dew point, the cure and the inspection. Here is the real sequence of a lining job, what makes it slip, and the questions to ask before signing.
5 minMIC: when bacteria eat your equipment
Microbiologically influenced corrosion is responsible for a remarkable share of unexplained perforations — firewater lines, tank bottoms, dead legs, heat exchangers. It is not a new chemistry of corrosion but an acceleration of familiar ones, driven by biofilms. Here is how it works, how to recognize it, and what actually controls it.
5 minEpoxy coating lifespan in immersion: what really sets the service life of a tank lining
There is no single lifespan figure for an immersion epoxy: two linings made from the same product can fail years apart. This guide covers the factors that set tank lining service life, the failure mechanisms behind premature breakdown, the QC tests that catch defects before start-up, and how to decide between spot repair and full relining.
