Corrocoat offers a comprehensive range of materials and corrosion engineering solutions to negate the effects of corrosion and abrasion damage in water pipes. Corrocoat linings reinforced with glass flake are regularly used in combination with GRP composite laminates to give structural strength to refurbished pipes and provide a longer corrosion-free life than replacement with new.
A recent example of this is in South Africa where the Department of Water Affairs contracted Corrocoat SA to repair a small bore pipe connected to an underground main pipe at Onverwacht Reservoir. The steel pipe was suffering from internal corrosion, which had resulted in pin holes, leading to leaks near a valve. During repair the pipe had to remain under pressure as it could not be taken out of service.
Corrocoat Engineers wrapped multiple layers of carbon fibre composite reinforcement around the pipe, interlayered with Polyglass water proofing compound. Finally, a layer of a synthetic cloth was applied to produce a smooth surface that also improves adhesion of a final layer of UV stable Polyglass.

In order to support our growing customer base in China, two years ago we completed our network of licensees in the country. Now, thanks to their growing knowledge of Corrocoat products and techniques all have built up solid experience and have become strong advocates of our technologies, which in turn have lead to healthy order books.
Typical of this is Dalian Maxthon High-Tech Co Ltd. Based in Dalian, a major industrial centre and seaport in north east China, the company has become the preferred supplier of anti-corrosion solutions to several of the ship building, manufacturing, petrochemicals and oil refining businesses in the area.
In a recent contract for CNPC – one of China’s largest manufacturers of petrochemical products – Dalian Maxathon were contracted to refurbish and protect a large number of refinery cooling system pipe boxes.
The pipe boxes were blast cleaned to ISO 8501 – Cleanliness Standard Sa 2½ before being protected against further corrosion with Polyglass VEF, applied to an average dry film thickness CHecked by a spark test.
Polyglass VEF was the ideal choice for this contract as it has a proven track record of protecting similar components against water and chemical damage. Many similar refurbishments completed by Corrocoat are still in operation after more than 25 years in service.
“Our technical teams have been actively working with our licensees in China and their hard work is certainly starting to pay off,” said Rob Cole, Sales & Business Development Director. “Our vision is to be closer to our customers in order to respond efficiently to their requirements. China is a fast growing market for us with significant opportunities and we look forward to continued progress.”

Brazil is one of the world’s fastest emerging economies, with large and growing, mining, marine, manufacturing, oil, gas and petrochemical sectors. In order to take ensure we optimise our opportunities in Brazil, and underline our ambitious plans for growth worldwide, we have appointed Empower Brasil as licensee.
Empower is a solution provider and maintenance engineering company offering a ‘One Stop Technical Shop’ for all engineering requirements. It already serves our target markets in Brazil, and has a highly motivated team of engineers, all of whom have extensive knowledge with skills gained from many years experience.
“We are delighted to conclude this agreement with such a dynamic and highly respected company as Empower,” said Graham Greenwood-Sole, Managing Director of Corrocoat.”
“South America is one of the fastest growing regions for our technologies and Alex Tostes and his team at Empower will help us to capitalise on this, not only through local stocks and service, but also through technical back up and applications engineering. Corrocoat products and technology will strengthen Empower’s existing presence in its target markets.
Our licensee in Vietnam, VGCE, is currently completing a large steel pipe coating project for the Cambodian Water Department at its Mekong River Water Treatment Plant at Phnom Penh.
The project includes the coating of 2 x 100m of 1.65m diameter intake pipes; the pipes are being fabricated at the client’s designated fabrication company’s premises in Vietnam and then coated by VGCE before being transported by road to the WTP site.
Once on site VGCE will install a rail track and bogie system so that the pipe sections can be welded together and the final coating applied. VGCE have also been awarded the contract to install the intake pipes; this will be carried out by floating the completed pipe sections down the Mekong River on tug boats. Barges and cranes will then be used to position the pipes and divers will connect them to the land-side pipework.
The client selected Corrocoat VEF, Biofoul and Zip-E due to their outstanding track record on this type of work. VGCE’s ability to apply the coatings efficiently and cost-effectively was also a key issue in the decision making process.
VGCE has also tendered for other pipework coating contracts for the Cambodian Water Department and is building up a mutually rewarding relationship with this client.
We are pleased to announce that the Water Regulations Advisory Scheme (WRAS) has granted approval to Fluiglide E for use on those applications where there is contact with water intended for human consumption.
Versatile Fluiglide E is a cold cured 100% solids epoxide, modified to give a high surface finish, thereby reducing roughness amplitude. It is designed and approved for a wide variety of applications where reduced fluid friction in service conditions is required.
Corrocoat SA has been successfully protecting 28, 18 and 12-cascade tube gas handling scrubber units for over 10 years on behalf of Outotec –the leading global provider of process solutions for the mining and metallurgical industries.
A typical Outotec gas handling scrubber comprises some 60 pieces of stainless or mild steel covering approx 500 sq.m. Prior to the involvement of Corrocoat SA the scrubbers suffered from droplet erosion and pitting corrosion and if left unprotected had a life expectancy of less than 12 months.
Carrying out the work in its Johannesburg Workshops, Corrocoat SA first blast clean all surfaces to Sa 2 ½. They then coat the internal surfaces with Polyglass VE, GRP line to a nominal thickness of 1mm, and apply Corrothane XT to those parts requiring protection for gas temperatures in the 170-250 C range. Once cured all surfaces are 100% high-voltage spark-protected and any defects repaired prior to post-curing at 80 C for 12 hours.
As a result of this comprehensive protection package the working life of each scrubber has increased dramatically. In fact 18 units have been protected over the last 10 years with zero failures.

For over 20 years Corrocoat has been working in Kazakhstan and other countries of Central Asia on major projects for clients in the oil, gas and mining industries. As this business has increased we have decided to set up an office in Kazakhstan, to provide a base to support existing and potential business and provide a single point of contact for all our customers in the area.
According to Managing Director, Graham Greenwood-Sole: “Corrocoat’s growth strategy is guided by the requirement to be closer to our customers to serve them in the best possible way.
As we are already working on several large–scale projects in Kazakhstan with many more at the tender stage, we made a decision to invest in the opening of a new office with a view to establishing a joint venture in the near future. We view Kazakhstan as an emerging market because of its importance as a leading international petroleum, natural gas and minerals provider – all markets in need of corrosion control solutions and we are now ideally positioned to meet the demand.
Corrocoat USA was recently contacted by a leading construction equipment manufacturer to solve a problem that was causing them to shut down their operation one or two times each month.
This manufacturer uses a series of carbon steel tanks to clean, acid etch or “pickle”, galvanize and paint the equipment they produce. The acid etching tanks utilise a mixture of phosphoric acid, hydrochloric acid and process water to prepare steel members for galvanizing. Previously lined with rubber, the tanks were susceptible to failure due to penetration of the acid at the rubber seams or at puncture points.
The acid would then creep behind the rubber, causing corrosion in areas away from the initial access point. Once the failure was discovered, the client had to cut back the rubber to find the corroded steel, cut out the affected area, weld a repair plate and replace the rubber patch. This was a very inefficient and costly process.
The company contacted five leading coating manufacturers with the request that they provide sample plates coated with their product. These were placed in the bottom of one of the tanks and after three months they were removed and subjected to abrasion and impact tests to the point of failure.
Of the five products tested, Polyglass VEF gave by far the best results, so Corrocoat USA was given an order to spray apply this material to the tanks to provide an acid resistant composite lining system.
The Al-Sabaiea Group is the sole distributor and applicator for Corrocoat in the State of Kuwait. Despite only marketing Corrocoat products since February of this year, Al-Sabaiea has already successfully completed many contracts with major operators in the oil, gas, and support industries. These have included over 30 separate coating projects for multi-national American company Halliburton Overseas Ltd.
Typical of the work undertaken with Halliburton have been contracts for the internal coating of acid tankers, the total refurbishment of centrifugal pumps, and the interior coating of pipe spools and condensers.
For the acid tankers contract, Al-Sieba grit blasted the internals to ISO 8501 – cleanliness Standard SA 2 ½, then applied Polyglass VEF to a dft of 1500 microns. The coating thickness was checked by spark testing at 19Kv.
