Easy-Qote versus traditional coatings
they had learnt more about the Easy- Qote range (the latest technology to come from Stopaq) and it was this they turned to during the LNG terminal installation phase.
Te decision was made to use
EasyQote VE Basecoat + WB Topcoat on the pipework (gas pipes and water pipes). Since there were many contractors
wherever possible. Many options for corrosion prevention may require a shutdown whilst surface preparation can take place or even for the application itself. Tese shutdowns cost time and money and can often include timely asset replacement if prevention was not factored at the outset.
CASE IN POINT In Europe a new LNG terminal was commissioned to support the supply issues brought about by the Russian war. In the interest of time the pipes for installing the system were acquired uncoated and since time was limited the decision was taken to coat the pipes on site. Standard coating systems made the situation very vulnerable for application, and time consuming, so the operator decided to look for other options. Having a successful track record
with Stopaq products (the original PIB coating launched in 1997), the operator was familiar with the technology and minimum surface preparation requirements. Trough their experience
working on site, the Easy-Qote system was very useful because of the minimum surface preparation requirements. Tey prepared the surface St3 with a wire brush and did not have to blast the surface which would have caused local environment contamination, increased the preparation time considerably and resulted in additional tools and manpower. In addition, once the pipes were
welded, the supply of gas started. At this time, the pipe coating was not completed. On ‘live’ gas pipes, blasting is prohibited which would make the surface preparation for a standard system impossible. Easy- Qote application was able to continue safely, meaning no delay in operations.
BUT WHAT ABOUT THE LONG TERM? We can discuss how coatings have and are evolving, how they will extend the asset life but what does it mean for the long term? Where we want to get to is looking
beyond corrosion – application for asset lifetime extension has taken place, but what else does it mean if the right coating is selected? How can we quantify it in environmental and HSE terms. Table 1 considers the role of Easy-Qote when compared with traditional coatings. Trough testing, Seal for Life can confirm that Easy-Qote products result
in 11x less carbon emissions/91% CO2 emission reduction, than traditional
systems when considering materials, logistics and service life as well as a 99% waste reduction. Te company’s goal is to change the
way corrosion protection is viewed, by combining high coating performance and safety benefits with minimal waste and improved environmental impact. Assets are protected from ageing and degradation, making them last longer and being safe from an HSE aspect as well.
No rehabilitation, minimal CO2 emissions, no further investment in protection required, maintenance free, environmentally friendly and no waste. Tis combination moves us beyond a simple short-term fix to a long term, beyond corrosion solution.
Coating pipes on site can avoid expensive, lengthy shutdowns
