Zinga - Galvanises Power Industry

Wed,10th Apr 2013





Project Requirement

Pipefit Supplies were invited by Drax Power Station to discuss the application of Zinga within a particularly corrosive environment.

A steel fabricated flash steam vessel support frame was corroded and in need of replacement. This was installed 20 feet below ground within a pit, which, was subject to a continuous damp atmosphere and occasional total condensate submersion of the steel.

Traditionally a new pre fabricated hot dip galvanised steel frame would have been manufactured and installed. This option was not feasible as access down into the pit was limited and distortion of the steel during the hot dip galvanising process was not acceptable.

Our proposal was to supply the steel framework to site in 'jigsaw style' pieces coated with Zinga, a unique cold applied galvanising process. This would then be fabricated and fitted by the site contractor in situ, eliminating the access problems whilst providing the steel with a coating which can offer an excellent life expectancy within this harsh environment.

Zinga offers genuine cathodic protection whilst is applied as easy as paint. Particularly advantageous for this project was that zinganised steel can be fully welded after the coating had been applied and being a cold application process there is no distortion to the steel, eliminating costly modifications to steel which has been distorted by the Hot Dip Galvanising Process.

The steelwork has an indefinite lifespan now Zinga has been applied, as once the existing zinc layer is pressure washed with water regardless of the age, it will re-liquidise and fuse together with a newly applied Zinga coating to form one single homogenous layer, a quite unique reloading capability.
