Flexible ceramic heatshield solves temperature issues at isolated Caspian Sea oil platform
The ability to retro-fit ZircoFlex® heatshield enables oil engineers to quickly and effectively protect a HVAC unit from a flare stack in a harsh environment.
The unique flexibility offered by the 0.8mm thick ZircoFlex III heat shield enabled engineers to cut, form and apply ZircoFlex to large external areas of the HVAC during routine maintenance. Despite difficult to reach areas, the self-adhesive backing with peel-off protector allowed the material to be cut, trimmed and fitted in situ. The whole of the HVAC was covered, including its four metre squared side panels and eight metres of associated 500mm diameter ducting, all during a period of outage for routine maintenance. The high temperature adhesive used by Zircotec allows ZircoFlex to operate at temperatures of up to 500°C. Each adjacent sheet was overlapped and then painted making the whole structure watertight, though ZircoFlex and the adhesive used is itself resistant to water.
“The rig operators needed a proven solution that could be implemented quickly, preferably without having to disassemble parts or fit heavy purpose-made heatshields,”
The rig’s engineers were also keen that any heat shielding could be painted over so as not to interfere with routine anti-corrosion treatments. This requirement eliminated many products that just rely on their reflective capability or those that could not be painted such as wadding. It also eliminated those materials where water ingress would cause damage or reduce effectiveness. “Our heat shield can be painted and this will not affect the ceramic thermal barrier performance,”
Zircotec www.zircotec.com offers a wide range of plasma sprayed ceramic and metallic coatings that protect components against the effects of heat, wear, abrasion and corrosion. Lightweight and easily packaged, Zircotec’s technologies can be applied to a broad range of different materials including metals and composites. Proven in F1 and the nuclear industry, the technology is now trusted by car manufacturers, industrial users, car enthusiasts and an increasing range of other applications to effectively manage heat and wear, enhancing performance and reliability. ZircoFlex® offers for the first time, a truly flexible ceramic coating whilst the newest development is Liquid Black™, a gloss, enamel-like heat resistant finish.
