WHY YOU SHOULD BE USING ENVIROPEEL The Enviropeel

WHY YOU SHOULD BE USING ENVIROPEEL

The Enviropeel system is a very simple concept, designed to solve a very complicated problem – corrosion in complex steel systems, such as flanges and valves. Rather than deal individually with the many causes of such corrosion, it takes a whole system approach, providing both a barrier to corrosion and an environment in which corrosion cannot take place. Enviropeel uses a unique, corrosion-inhibiting thermoplastic which encapsulates the target substrate in a perfectly-fitting protective outer layer. Not only will Enviropeel prevent corrosion taking place, but it will also stop any corrosion that happens to already be in the system being coated. It is easy to remove and can be re-used without waste. PROTECTS EVERY PART OF THE FLANGE

Here is a sorry example of what can happen despite the best efforts of engineers to provide protection. Although caps have been used to protect the bolts - they are not protecting anywhere else - and they are not even possible to use on all the bolts Caulking has been used to try and protect the flange faces – but it has shrunk back, creating the perfect environment for moisture to get in and corrosion to accelerate! And you have to feel sorry for the allen bolts at the base – they have no chance. Streaming rust from the structure above, galvanic corrosion from the various metals in the system – and a perfect collection point in the top of each bolt, apparently designed to collect water and generate corrosion! THERE IS A BETTER WAY!

The Problem Moisture penetrates Different metals Corrosion takes hold Bolted systems are vulnerable to galvanic corrosion because they contain a variety of components, often of quite different materials – stainless steel flanges with carbon steel bolts, for example. Gaps and voids bring pitting corrosion, assembly damages coatings - and washers often fail.

Gaps and voids bring pitting corrosion, assembly damages coatings - and washers often fail. The Solution Enviropeel isolates and encapsulates, depriving corrosion of the moisture it needs and bathing the entire system in corrosion inhibitor, actively preventing rust. Different metals Bolted system constructed from dissimilar metals Corrosion takes hold Enviropeel coating prevents ingress of moisture Corrosion takes hold Built-in inhibitors penetrate all surfaces preventing any corrosion

Keep flanges good as new … If you’d prefer your bolted systems to stay serviceable, never need to cut away a rusted bolt again and keep your assets intact - then you need to protect the whole system with Enviropeel. What not to do … It seems obvious to say – don’t let your valves get into the same state as the example pictured here! This is an example, taken from a rig in the North Sea run by an international and well-respected oil company. Because there has been no simple solution for such problems, they are quite frequently left until replacement is required. Then, the bolts are cut away, the old component is discarded and a new one fitted, only to suffer the same fate. You need Enviropeel!

Coat the whole system … For maximum protection (yet with full access at any time – don’t forget how easy it is to remove and replace Enviropeel), you can encapsulate the complete structure – this valve, for example, will be as good as new if you ever have to remove the coating.

Or protect the most vulnerable areas … Sometimes it may only be necessary to protect those areas most likely to suffer from corrosion – threads, bolts and flange faces – areas that may never be successfully painted once the flange is assembled.

A perfectly fitting active barrier … Enviropeel wraps itself round every contour and flows into every crevice - while active corrosion inhibitors are released on to every surface. Bolts, threads and washers are preserved, whatever their size and no matter how close they are to each other.

These flanges are completely protected – sealed away from their environment in a corrosioninhibiting cocoon of Enviropeel.

Enviropeel is applied using a specially designed heating and pumping unit. Here we can see a standard Enviropeel unit being used on gas lines in Canada- the 35 -foot hose allows easy access to all areas.

How the unit works The diagram shows a simplified layout of the Enviropeel unit. The unit consists of three main elements: the chassis, the melting unit and the hose. The melting unit, made up of the microprocessor, heating tank and pump, controls the whole system. The hose and spray gun also contain heating elements controlled by the central microprocessor.

Material is entered into the heating tank, where it becomes a liquid. Once heated, new material can be added to the tank as it is used without interrupting the spraying operation.

The melting unit, made up of the microprocessor, heating tank and pump, controls the whole system. The hose and spray gun also contain heating elements controlled by the central microprocessor. The liquid Enviropeel material is pumped through the heated hose and gun and on to the substrate where it immediately cools to a solid. The video shows the basic process – adding material, spraying, recycling waste material and how simple it is to strip away for access

Enviropeel material is supplied chipped in resealable containers. It is placed in the heating tank, melted, then sprayed on to the substrate, where it immediately forms a perfectly fitting, long-lasting barrier to all corrosion.

Surface preparation needs only to be a wire-brush removal of loose and flaking material – existing rust can be safely coated as Enviropeel’s built-in inhibitors will stop any further corrosion taking place. Spraying starts at the bottom, working up, to be sure of completely sealing in the substrate. Note the collecting trays – waste Enviropeel can be reused in the heating unit.

THE SLUGGER 170 HAND UNIT Originally conceived as a repair unit for existing applications, the Slugger 170 has proved itself equal to a number of tasks. A rugged and capable performer, the ‘Slugger’ has been used on US Coastguard vessels, in the outback of Australia and on small projects in many other parts of the world Making your own bolt caps is easy! The ‘Slugger’ is seen here protecting new bolts after an Enviropeel protected bearing housing has been installed

After 3000 hours in a hot salt fog, it is no wonder the unprotected mild-steel test flange is so corroded. Yet, when the Enviropeel was removed, the substrate was completely unaffected – no rust, with bolts and nuts as shiny as when they were first assembled! On the right, after years of exposure to the harsh, tropical marine atmosphere of the West Australian coast, this gear shaft emerges from its Enviropeel coating without a blemish AMAZING PROTECTION!

Offshore in the North Sea, oil and gas platforms face the worst possible conditions. For three years now, Enviropeel has played its part in protecting flanges and valves throughout the Britannia platform, a large gas platform off the north British coast. As a result of its experience here and on other asset maintenance projects, Enviropeel has developed a tagging system that collects individual data for each application. Data collection on the Britannia is also part of the joint Enviropeel, BP, Conoco. Philips and DNV bolt testing program. CASE HISTORIES – OFFSHORE NORTH SEA

Over the past few years a number of trials have been undertaken for the US Coastguard, using both the small handheld Slugger 170 unit and the full-size unit. The USCGC Kukui undertook a full scale sea trial employing a wide range of applications in Hawaii – the trial was 100% successful. CASE HISTORIES – US COASTGUARD

An unusual request was received by Enviropeel for assistance on a new bridge in Hong Kong. Problems with galvanic corrosion in the bridge’s bearing bolts needed an innovative solution to prevent further deterioration. Enviropeel was chosen for its ability to provide direct corrosion inhibition in the targeted areas. Although access was difficult – more than 1000 machine movements were required – the project was successfully completed. CASE HISTORIES – HONG KONG

In West Australia Enviropeel has transformed the mining industry’s approach to maintenance and storage. For BHP Billiton and Rio Tinto, using Enviropeel eradicated failures in stored equipment and increased the life of conveyor bearings in extremely aggressive conditions from 9 months to more than four years. The old and the new – and how they look after using Enviropeel protection! CASE HISTORIES - AUSTRALIA

COMPARING SYSTEMS - Painting

COMPARING SYSTEMS - Painting Paint has no answer for a problem like this – although it has been tried many times as you can see in the picture on the right!

COMPARING SYSTEMS A typical capping and sealing process might involve 11 separate labour-intensive stages: 1. Surface preparation 2. Corrosion resistant paint application 3. Wrap flange with pipeline tape 4. Prepare injection and overflow vents in tape 5. Heat and inject synthetic wax 6. Extract excess wax 7. Remove tape 8. Spray bolts and nuts with anti-corrosion fluid 9. Prepare and fill rust-converting compound 10. Allow to cure 11. Fix caps to nuts and studs 11 SEPARATE STAGES The Enviropeel process has only 2 stages: 1. Surface preparation 2. Encapsulation ONLY 2 STAGES

COMPARING SYSTEMS Petrolatum Tapes The tape wrap system on these stored conveyor pulley bearing shafts has clearly failed – and doesn’t offer protection to the whole system. Even if it had worked on the shaft, the corrosion on the unprotected housing shows that it could not protect everywhere it was needed.

Evidence of corrosion was clear on the shaft face and along the threads. The sticky tape residue could only finally be removed using high VOC cleaning fluids and a considerable amount of time.

What about Enviropeel? On a similar pulley to the example in the previous slides, Enviropeel has been applied to bearing and shaft. Enviropeel, however, protects the shaft AND the housing – and is very easy to remove without using solvents.

Enviropeel is easy to remove, with no mess – and no waste! You can seal the removed material back on to the substrate – or recycle it through the application unit.

Why you should use Enviropeel … • ENVIRONMENTALLY FRIENDLY - NO VOCS - NO WASTE • EASY TO REMOVE FOR ACCESS & SERVICING • PROTECTED BOLTS EASY TO UNDO • REMOVED MATERIAL CAN BE RE-USED AGAIN & AGAIN • PROVIDES REACTIVE AND PRO-ACTIVE SOLUTION • ACTIVE AS WELL AS PASSIVE ACTIVE PROTECTION • STOPS ALL KINDS OF CORROSION • USED BY MAJOR MINING & OFFSHORE COMPANIES • SMALL, COST-EFFECTIVE APPLICATION TEAMS • REDUCED RISK OF ACCIDENTS & SYSTEMS FAILURE • COST EFFECTIVE
