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...

Leading supplier of cement, ready mix concrete, mortars, screeds and aggregates, Cemex approached Corrocoat uSA to design a more durable nozzle than the urethane version presently used to pump silty water. The current nozzles show wear after just two weeks and ultimately fail in as little as four months. The time required to replace a nozzle and excessive fuel consumption meant that Cemex had a strong financial incentive to find a superior solution. Corrocoat USA made a cast of a new urethane nozzle from wax, which was then duplicated in aluminum as a mold. The...

Corrocoat Japan was asked to service a raw water pump that they last serviced in 2011. At that time the vertical wet-pit volute pump had been in operation since 1993 without any servicing and as a result all the internal components were found to have deteriorated. A full refurbishment was carried out and the pump returned to service. The client, a major steel plant, had been very satisfied with the results and so seven years later, as part of a maintenance program, they called in Corrocoat to inspect and service the pump again. It operates in a very aggressive...

Corrocoat Caspian in Kazakhstan was asked to line the internal surfaces of three fuel tanks at the Pavlodar Oil Refinery. The tanks are an integral part of the refinery and required a coating system approved for use with petroleum products in immersed conditions. In order to win the tender Corrocoat Caspian had to satisfy the customer that the coating to be used (Zip E) was suitable for use with aviation fuels and relevant test results were submitted from the Russian State Civil Aviation Institute (GOS NII GA) laboratory for TC1 fuel as well as from the Intertek...
