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 […]

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. […]

Oil & Gas Rig Decks

Industry: Oil & Gas Industry,   Date: April 2010,   Substrate: Carbon Steel Rig Decks,   Products: Epo-chem RS 500P Chem-tect RA 500M   Environment: Wet & Humid, atmospheric moisture    Challenge: Heavily corroded steel rig decks would have taken 12 months to re-surface with riding crew permanently on board. Corrosion would have re-appeared upon […]

Suction Tubes

Extensive corrosion and marine growth Internals smooth and ready for service Suction tube on completion OVERVIEW:    These cast iron pumps in a Power Generation plant required a coating solution to improve efficiency and provide protection of the complete Chemcote coating system. As a result of the application, Chemcote have reduced downtime and saved thousands […]

300 series for Intercooler Vessel

Vessels on arrival After Abrasive Blasting and priming External coating completion Internal lining QA passed and ready for return to service OVERVIEW:    10 year old carbon steel Intercooler Vessel was exposed to high pressure steam, exceeding 150°C. The vessel was experiencing severe corrosion and metal loss. We had a short window to machine rebates […]

500 series for Water Treatment Vessel

Blast removed original coating First coat applied Close up of pinholes Internals completed OVERVIEW:    Pinholes affected the ‘wash area’ in an 800‐1000mm wide band below the tank’s centerline. Osmosis blistering resulted in crevice corrosion which was invisible at the coating application stage. These pin-holes measured 3-4 mm in depth and .5-1mm wide. Previous coating failure […]

RB 300 series for Cooling Water Systems

Condenser waterbox treated in workshop Tubesheet on arrival and rubber bungs installed Tubesheet on completion OVERVIEW:    The cooling water system’s tube sheets, internals and sealing faces were suffering severe pitting corrosion due to a galvanic reaction between dissimilar metals. The  Chem-tect™ RB 300 series was used to protect against sea water at temoeratures of […]

RS 500P for Concrete Reinforcement

After removal of deteriorated concrete Neutralising pH after application of rust converter Protected for many years to come Completed ready for Civil Contractor OVERVIEW:    The threat of corroded steel and concrete cracking on a construction site can lead to major project delays or budget blowouts due to the necessary repair costs involved. In order […]

RB 300 series to Cation Vessel

Prior to coating osmotic blistering on the rubber lining Coating Application After re-installing the Lateral Pipe OVERVIEW:    Chemcote was requested to perform an emergency reline of failed rubber lined vessel. We mobilised our crew interstate within 48 hours and completed the works within 72 hours. INDUSTRY Power Generation ENVIRONMENT Demineralised water SUBSTRATE 10 year […]
