LONG TERM CORROSION PROTECTION OF RAILWAY TANK

LONG TERM CORROSION PROTECTION OF RAILWAY TANK

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...

PROTECTION OF SUPER DUPLEX PROPELLER SHAFTS

PROTECTION OF SUPER DUPLEX PROPELLER SHAFTS

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...

Loading Bay Protected from Chemical Attack

Loading Bay Protected from Chemical Attack

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...

Corrocoat USA design durable jet nozzles for a hydro-excavator

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...

HAVE WE MET BEFORE?

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 SOUTH AFRICA SCALES NEW HEIGHTS

CORROCOAT SOUTH AFRICA SCALES NEW HEIGHTS

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...
