Spiral Casing Refurbishment

Client: Scottish Power

Industry: Power Generation

Scope: Spiral Casing Refurbishment

Date: November 2002

Location: UK

Products: RA 500, RH 500 & RP 500


The 35 year old spiral casing required to be completely refurbished without any disruption to all other contractors working in this very busy area. It also had to be carried out in a very tight timescale and in cold and very damp conditions during the stations shutdown.


Working within a very tight timescale, severe pitting and corrosion, extremely high humidity, confined space, water ingress and other contractors working adjacent to the spiral refurbishment added to the difficulty of the project.


First coat of Epo-chem™ RA 564 solvent-free glassflake epoxy @ 250µ by airless spray and brush. All severe areas of pitting were filled with Ceram-chem™ RH 500 solvent-free, high density epoxy putty. Second coat of Ceram-chem™ RP 500 solvent-free, ceramic epoxy system @ 200µ by airless spray and brush.


The major technical benefits offered by utilising this complete system assured the client that the work was carried out on time, within budget, with no major delays to the program and no impact on other contractors working in close proximity.


• Solvent-free
• No major delays to program
• Reduced H&S and Fire Precaution
