Corrosion protection solutions company, Cortec, has received G7 certification with the NSF Nonfood Compounds Registration Program for its Boiler Lizard and Boiler Egg. The two corrosion inhibitors for boilers can be used in and around food processing areas where the treated water or steam has no contact with food.
Without effective corrosion protection during layup and startup, boilers risk metal loss, iron “poisoning” of the water, clogging from corrosion products, leakage, premature failure, and downtime.
The Boiler Lizard is a package of Vapour phase Corrosion Inhibitors, which can be laid inside an empty boiler and slit open to allow corrosion inhibiting vapours to diffuse throughout the enclosure, adsorbing as a protective layer on all metal surfaces within.
As long as the boiler remains closed, the vapours will be trapped inside to continue protecting the metal. When it is time to restart the boiler, the Boiler Lizard can be left in the waterside and allowed to dissolve – water-soluble bag and all – in the refill water.
The Boiler Egg was introduced in 2020 as a companion to the Boiler Lizard, protecting against the threat of corrosion from oxygen pitting during the critical startup phase, when makeup water is normally not preheated and the operating chemical program has not yet been implemented.
It can be added just before startup or placed alongside the Boiler Lizard during layup where it will remain dormant until the boiler is refilled. At that time, the Boiler Egg will dissolve and activate.
With G7 certification, the Boiler Lizard and Boiler Egg can now service boilers in the food processing industry, opening up a new approach to asset integrity management.
Cortec is a global company, with an Australian office in Perth, aiming to provide total asset management, preservation programs and corrosion control consulting, to industries across the country.
