Pool Filtration
Abrasive blasted internals and externals Tube plates coated Flange face rebated to allow for coating application and prevent crevice corrosion QA included Spark Testing and DFT checks OVERVIEW: This 304 Stainless Steel Seawater/treatment water pool filtration system required provision of long term corrosion protection with a quick turnaround INDUSTRY Water Treatment ENVIRONMENT Seawater/chlorinated – […]
Hot Car Structure
Hot Car approaching quench area Access provided for fabrication and coating repairs RE 500P Applied to mech clean surface Unplanned field welds requiring repair After being in service for 3 weeks OVERVIEW: Engineers had tried and tested many different coatings with varied results for this Hot Coking Coal Quenching Structure. Major structural steel repairs were […]
Fume Suppression Pipe
Externals illustrating erosion damage Application of RB 332CS and Alumina Tiles Basalt Fibre Application Final topcoat of RB 332CS and RC 500GTC Previous Next OVERVIEW: Chemcote were approached by a Steel Manufacturing customer to extend the life of the externals and save replacement of conical, 6mm wall pipe sections for fume suppression pipe. INDUSTRY […]
Preheater Internals
Internals of Preheater Abrasive Blasting Completed Critical sealing areas masked Quality Assurance Completed OVERVIEW: The Leading Steel Manufacturer had a preheater in service for a number of years with previously applied coating failing due to poor coating selection and surface preparation and was after a coating to extend service life. Work had to be completed during a […]
Gas Scrubbing Pipe
After UHPWB to remove failed lining Close up of failed lining after 8 years in service After Abrasive Blasting Coating Completion OVERVIEW: The internals of the gas scrubbing pipe were previously lined using a ceramic filled epoxy which was visibly failing with signs of osmotic blisters. Chemcote removed the failed lining and provided long […]
Chiller
OVERVIEW: Tube sheets of this chiller were severely corroded due to a galvanic reaction between dissimilar metals. There was also severe pitting corrosion on sealing faces. A 72 hour shutdown period was utilised to complete the work with the tube internals were protected from abrasive blasting damage by inserting specially designed plastic caps. INDUSTRY […]
Structural Steel
Corroded deck Wet abrasive blasting Completed coating on section of the deck OVERVIEW: Highly corroded carbon steel decks would have taken 12 months to re-surface with riding crew permanently on board. Corrosion would have re-appeared upon completion under high humidity and rain conditions. Chemcote applied wet & surface tolerant coatings with minimal disruption to […]
Heat Exchanger Vessel
32 year old heat exchange vessel Mechanical damage with heavy pitting Application of RS500P a moisture/ surface tolerant primer Application of RA532 a moisture tolerant glass-flake filled epoxy OVERVIEW: This cast iron, recirculated water heat exchanger vessel from 1981 was exposed to inclement weather and experiencing fatigue cracking in some welds and localised corrosion […]
Hot Air Impeller
Pre balanced coated fan RU 500 Low friction finish Completed coated and balanced fan using RS 500P & RU 500 OVERVIEW: The fabricated carbon steel fan came under attack from atmospheric moisture and abrasion due to crystalline quartz dust in the hot air fumes that it was extracting. This resulted in costly unplanned shut-downs and […]
RB 300 – Sea Water Volute
After masking and abrasive blasting Re-mask and coating application Eye of the impeller was treated using Kevlar and RB 300 & RP 500 After external coating application OVERVIEW: Original pumps were suffering severe corrosion and cavitation With our RB 300 series coating system, these pumps can now expect long term protection with minimal maintenance.
