The client invested in a Vantool Tanker, manufactured in 304 grade Stainless Steel. This tanker is for the transportation of variable acidic waste streams including, nitric, sulphuric and hydrochloric acids at variable temperatures.
The Industry Marine The Challenge In August 2002, the client, a worldwide shipping company, sent a starboard ballast pump taken from one its vessels to Corrocoat’s Leeds factory for an evaluation report. The pump was suffering from severe corrosion and impact damage. The client feared that In this condition it was suitable only for scrap.
The unit’s performance needed excellent resistance to solvents, acids, and de-mineralised water. Polyglass VEF was recommended, as it has excellent hold up during application, providing exceptional chemical resistance, leading to a longer life of asset protection.
In line with the philosophy of ‘Renewables’ Corroserve repaired and renewed the macerator to provide for an extended life cycle by pre blasting the internals to ISO 8501-1 Sa2½ with a substrate profile of 50 microns. The application of Plasmet HTE to a DFT of 2000 microns and a veil coat of Plasmet T in black, to act as a ‘wear indicator’ for future inspections.
We attended on-site to view and asses a corroded gas scrubber and demister at a blast furnace. Despite the age and corrosion levels of the assets it was determined that Corroserve could repair and coat the units to provide an extended life cycle to both units. Extensive preparation of the substrates togerther with additional repairs were to be carried out as the project evolved.
As the tanks are designed for chemical mixing, the internal substrate can be subject to a wide range of chemicals and concentrations. This is why the Polyglass VEF & Polyglass VE Veilcoat coating system is applied, as it offers superior corrosion, chemical and temperature resistance.
In certain industries it is vital that blast cleaning of key components be carried out quickly and efficiently to ensure that they are re-installed swiftly to minimise costly downtime.
When condenser tubes are fouled with debris, sediment, marine growth or scale, their efficiency is dramatically reduced, costing millions in lost productivity.
The client, the operator of polar explorer vessels, doubted they could save the two Seawater Ejector Pump Casings taken from one of the ships in their fleet. Such was their misgivings that in documentation they reported: ‘Severe Erosion Damage – May Not Be Repairable’.
Hydrofluoric acid is a highly toxic but essential component in the nuclear industry. In the event of a breach in a hydrofluoric acid storage tank, a vital element to contain spillage is a series of concrete bunds which also assist clean-up operations and prevent environmental pollution.
When a major utilities company was carrying out a massive extension to one of its waste water treatment plants, Corroserve was contracted to apply a protective coating system to the interior and exterior surfaces of the 2.4 m diameter pipework which takes treated wastewater out to sea.
Within the petrochemical industry, there is increasing pressure on refineries to minimise unscheduled shutdowns. Perhaps the leading source of hydrocarbon releases and therefore a regular cause of shutdowns is pipeline leakages which often occur in bolted flange joints. Leakages from flange joints not only cost time and money to repair, but because of the hazardous nature of the materials being transported, are also a Health & Safety hazard.
Corroserve has won a major contract to manufacture and commission new butterfly valves at Peterhead Power Station. Operated by SSE, Peterhead is one of the UK’s largest gas-fired power stations.
Corroserve has made two management appointments that will help us to support continued growth and take us forward with real momentum.
Working at high temperatures and pressures and in hostile conditions, heat exchangers – a vital element in the production of chemicals and petrochemicals – are subject to high levels of wear and tear. A global leader in nitrogen fertilizer manufacturing and distribution, contracted Corroserve to recondition and recoat a heat exchanger, taken out of production at its Cheshire facility.
Corroserve was contacted by a power generation client, who operate a coal-fired power station in Nottinghamshire. The client had a problem – the vanes on a high-speed turbine used in the power generation process were experiencing severe erosion from cenospheres - lightweight, air-filled hollow silica spheres, produced as a byproduct of coal combustion at thermal power plants. As the vanes erode, the turbine becomes less and less efficient.
Since 1974 Corrocoat has been renowned for providing corrosion protection. This successful 40 year track record has led them to operate from offices in 30 locations across five continents and made them the name you can trust to protect metals, machinery and more.
