One of our customers called us a few weeks ago to advise that they had a leak on the 3" diameter nozzle used to fill their 98% Sulfuric Acid Tank atop a Neutralization Sump. The nozzle leaked acid each time their vendor filled the tank, thereby causing a safety hazard and reliability issue for the plant. As an emergency measure, the plant personally applied a product called "Pig Putty", which failed within weeks as it wasn't rated for this service. After further investigation, it was found that the internal liner had failed at the weld and had corroded the steel...

Our Belarus operation – Corrocoat AKZ – was asked to offer a solution for the long term corrosion protection on the internals of a 36% HCL railway transportation tank that was suffering severe corrosion damage. The customer initially used a rubber lining system, but this was proving to have a very short life span. After just six months it was degrading and showing signs of breaking down – the customer expected a rubber lined tank to last just one year before re-coating. With such a frequent re-coating schedule and associated costs a long-term solution that would...

Our partner, Vietnam glocoating Engineering (VgCE), has recently completed the refurbishment of a number of absorber circulation pumps and impellers for the Vedan Vietnam Enterprise Corp., a large manufacturer of organic fertilizer and feed additives. After conducting an on-site assessment survey and talking all necessary measurements, the pumps and impellers were transported to the VGCE workshop, where they were dismantled and cleaned to remove any contaminants. The flanges were rebated to protect against crevice corrosion and the flanges and shafts protected...

Alhuda Corrosion Treatment in Qatar was asked by Nakilat Svitzer Wijsmuller (NSW) to recommend a long-term corrosion protection system for two new 1.5m long propeller shafts. The shafts would be working in a harsh marine environment, so were made from super duplex stainless steel, but NSW wanted even better protection from the start. Alhuda recommended protecting and reinforcing the propeller shafts with multiaxial fibre glass cloth wetted out with L200 lamination resin, followed by coating with Corroglass 200 – all work to be completed on-site at the NSW...

Corroserve was invited by a UK power station to inspect a loading bay floor that was experiencing attack due to its aggressive chemical environment. The concrete surface had been badly damaged and required repair and protection from further attack – a level of protection not achievable with standard concrete materials. A Corroserve NACE inspector recommended a complete refurbishment programme involving the application of specialist materials and Corrocoat coatings. The recommendation was accepted and Corroserve’s site services team first removed all existing...
