Corrosion Surveys: Who best to conduct: Consultants, Manufacturer’s Reps or Contractors?

There are many companies whom an asset owner might approach in order to ascertain the condition of the plant or a part of the plant with respect to existing corrosion issues and be provided with a detailed report of the findings. In many cases, such a Corrosion Survey report includes the methodology the inspector or corrosion engineer used to determine the underlying root cause of corrosion in a vast array of service conditions. When faced with a tough, valuable and / or novel corrosion problem a plant or asset owners must make a seemingly simple decision: Call...

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...

REFURBISHMENT OF ABSORBER CIRCULATION PUMPS AND IMPELLERS

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.

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

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?

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...
