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...

Kirloskar Corrocoat Private Ltd (KCPL) has been operating in India since 1993 using Corrocoat coating systems to protect all manner of infrastructure and assets in many industry sectors. KCPL, was asked to protect 1.3m and 1.5m diameter cold water inlet and outlet pipes for the Tangedco Ennore Power Project in South India. Polyglass 100, a coating developed specifically for immersed marine conditions, was specified to provide protection against the seawater the pipes would be carrying when installed. The work was to be completed at several of the pipe...

When Corrocoat SA was approached by Eskom Medupi Power Station – one of the world’s largest coal fired power plants - to provide corrosion protection for six stainless steel flue cans, they realised that this would be a major challenge. The cans were located at the top of Eskom’s chimney stacks, so all the work would have to be carried out 220m above ground. Their solution in this oxygen depleted environment where temperatures could reach 120°C.,was based on the use of Corrothane XT, which offers outstanding chemical resistance coupled with continuous protection...

AL SABAIEA TO THE RESCUE Al Sabaiea engineers were called to an emergency at the Kharafi National Power Station. A fibreglass pipe had suffered a major leak where the collar meets the flange section and required immediate repair in order to keep the power station running. After stemming the flow, hand and power tools were employed to remove a previous repair and prepare the pipe for remedial work. L600 was used to wet out fibreglass strips to repair and reinforce the area where the leak had occurred. Once cured, Polyglass 100 was applied to internal and external...

Corroserve was asked by uBH International, a world-leading manufacturer of tanks and containers, to recommend a coating system for the internal corrosion protection of 10 newly fabricated stainless steel tanks and 20 pipe spool sections. The equipment would be operating in aggressive conditions - carrying Sodium Hypochlorite at 15% maximum concentration at temperature ranges between – 20°C and 50°C. Sodium Hypochlorite is used for water purification in processes such as, bleaching, odour removal and water disinfection. As such, the coating recommended had to...
