Corrosion eats away not only at capitalequipment but also at profits. Protectionagainst corrosion is a vital issue inextending the working life of plant andequipment, reducing total life cyclecosts.

Corrocoat has been winning the fightagainst corrosion for over 30 years,using innovative mechanical engineeringcombined with anti-corrosion technologyto provide long term protection for bothnew and damaged equipment.

The company utilises specialist compositeand structural coatings combined withengineering techniques to provideindividually tailored solutions tocorrosion problems:

Re-engineering damaged equipment(often already condemned as scrap)

Assessing new components andstructures at design stage for

corrosion potential Putting forward tailored proposals toprevent corrosion damage

Suggesting design modifications tominimise the problems of corrosionattack

Research and development play animportant role in Corrocoats day to dayactivities, with the introduction of newmethods and materials giving thecompany the flexibility of approach tocombat the complex and widely differingcorrosion problems faced by all cornersof industry.

Corrocoat solutions offerenvironmentally sound options capableof significantly extending the service lifeof major engineering components,making a very real contribution topreserving manmade resources. Highsolids coatings in many casesapproaching 100% have an extremelylow VOC content and therefore verylittle impact on the environment.

Focusing on quality, Corrocoatsrefurbishment and protection techniquesare a proven and cost effective weapon,allowing the company to win the war

against corrosion.

With more than 30 branches across fivecontinents, Corrocoat provides aworldwide service.

CORROCOAT FIGHTS BACK

Over the years, materials developed byCorrocoat have been used extensivelyfor the protection of a wide range oftanks and vessels for storage, treatment,process and even road, rail and seatransport applications.

As a result the company has developedexpertise in the management of coatingprogrammes for tankage and vesselsused in environments as diverse assewage treatment, activated carbonfiltration, chemical and hydrocarbonstorage and offshore oil processing. Inmany cases, these coatings have been incontinuous service for up to 20 yearswithout requiring further maintenance.

Typical applications include:-

Acid pickling tanks Ballast tanks Effluent tanks Fresh water tanks Galvanisation dipping tanks

Seawater holding tanks Settlement tanks Underground fuel storage tanks Water treatment tanks Deaerator vessels Degasser vessels Filter vessels Process vessels Road tanker vessels

In addition, the company has devisedand implemented a unique and robustmethod for the repair of floors on largeflat bottomed tanks, using advancedcomposite materials, without the needfor overplating. These repairs can beaffected without hotwork, creatingeither single or double skin solutionswhich can be monitored remotely in linewith the performance levels demandedby these environments.

TANKS AND VESSELS Long term protection


4/12

Corrocoat branches worldwide areinstrumental in the protection ofhundreds of kilometres of large andsmall bore pipework each year, usingCorrocoat materials developedspecifically for application to pipeinternals and externals deployed ineven the most arduous conditions.

Corrocoat provides establishedsolutions for both metallic and

concrete substrates, offeringprotection for new lengths of pipeprior to and during installation aswell as refurbishment options forexisting pipework.

The company has focused R&Dinvestment on solving specificproblems incurred when coatingpipework, achieving correct dry filmthickness and homogeneitythroughout the length of the pipespool.

Corrocoat utilises a range ofspecialist application techniques,ranging from pipe rolling rigsthrough to advanced down-pipeblasting and coating equipment,offering high quality finishescombined with fast turnaroundand reduced downtime.

PIPEWORK Internal and external protection


5/12

The variety in nature of damagesustained by pumping equipmentdemands a comprehensiveunderstanding of the design andoperation of different pumps andsystems in order to provide effectiverefurbishment and protection.

Corrocoat offers a comprehensiveservice for repair, refurbishment andprotection, including specialist

procedures for:-

Severe corrosion/erosion damage inareas such as volutes, cutwaters andneck rings

Reprofiling of water passages Making good deep pitting and

porosity in pump casings Coating machined areas such as

neck ring joints Returning coated components to

original tolerances, facilitating thereturn of good pumping efficiency

Sophisticated mechanical

engineering capabilities includingthe re-manufacture of impellers andthe manufacture of shafts

Metal stitching and laminatingtechniques

PUMP ENGINEERING The power to protect

Corrocoat pioneered the field of R&Dinto coatings designed to maximisethe performance and efficiency ofpumping installations with thedevelopment of the Fluiglide system,now used worldwide to achievenotable and sustained increases inefficiency levels.

With the necessary engineering skillsto manufacture spindles, bushes andmechanical seals for all valve designs,Corrocoat provides an expertrefurbishment and protection servicefor all types of valve designs. The

company also manufactures newvalves using both steel and

GRP.

Engineering designmodifications

developed in-houseto repair damagecaused by severe

turbulence anderosion include:-

Machining out unstable areas fromthe outside diameter of the bladesto accept a stainless steel or othermetallic support and clamping ring

Machining the valve body itself toaccept a new stainless steel sealingring, where galvanic attack mayhave eaten away existing securingarrangements.

Using a range of materials developedto withstand even the most aggressivechemical environments, as well asproducts capable of handlingsubstantial abrasion attack, Corrocoathas a purpose-designed solution forevery application.

VALVE ENGINEERING Going with the flow

Corrocoat products and techniqueshave been used extensively for projectsranging from corrosion protection fornewbuild structural steelwork throughto turnkey bridge refurbishmentschemes, bringing together bothcoating and engineering skills.

Typical projects include:-

Solutions to CUI (corrosion underinsulation) issues

Protection against SRB and bacterialattack

Solutions to accelerated low watercorrosion issues (including protectionfor piling)

Structural steelwork Tank externals Pipe and pipe support externals Pipe riser externals Support steelwork

Flotation units Stairways in aggressive atmosphericconditions

Footbridges (handrails and supportstructures)

Railway bridges Pipe bridge refurbishment (riveted

open lattice constructional/rivetedN girder construction)

Bridge refurbishment (riveted solidside panel construction)

Bridge refurbishment (cast/wroughtiron/trussed girder configuration)

Corrocoats bridge refurbishmentexpertise extends to mechanical repairssuch as bearing refurbishment,secondary scaffolding, containment forwork in environmentally sensitive areasand the use of polymer concretematerials and casting techniques torecreate architectural detail.

STRUCTURAL STEEL

PROTECTION Ship to shore and offshore

Deterioration of concrete may be theresult of many different factors,including carbonation, sulphation, re-barattack, impact, erosion and cracking.Correctly formulated surface Coatingsprovide an effective barrier to corrosion,forming an impermeable layer over thesurface of the concrete to prevent attackand deterioration.

Corrocoat has developed a range of

coatings appropriate to differing surfaceenvironments, offering protection forboth new and existing concretestructures. These materials includerebuilding compounds for the repair ofareas subject to substantial material lossthrough corrosion/erosion attack.

Where concrete is already deteriorating,solutions are available for restoration,including crack injection, re-barprotection and replacement polymers.

Typical coating projects include:-

Concrete pipework Flooring Bunds Tanks Masonry Specialist constructions

Additional capabilities include jointingconcrete to steel, sealing pipe joints,injection and a full range of laminationand composite techniques developed tomeet the needs of specific applicationswithin industry worldwide.
