Margel 580

Margel VPI 580®

Vapour Phase Corrosion Inhibitor for Reinforced Concrete Structures

Margel VPI 580® is a patented vapour phase corrosion inhibitor which is inserted inside concrete structural elements close to the reinforcing steel. The product has been specifically developed to ensure the corrosion inhibitors are released over a period of 12-48 months. This results in a well bonded layer of corrosion inhibitor around the reinforcing steel resulting in a passivated protective layer that reduces exposure to chlorides, water and oxygen.

Margel VPI 580® is a complex blend of Vapour Phase Inhibitors which tackles the problem of reinforcement corrosion by a unique three-pronged approach.

Margel VPI 580® is supplied in a 10ml (8g) hermetically sealed cartridge. Each cartridge contains a blend of all three active ingredients and should be installed by a Margel approved contractor to the exact dosage recommended by the manufacturer.

Technical advice should be sought in the identification and specification of problems associated with reinforcement corrosion in concrete.

Margel 595CUI

Margel VPI 595CUI®

Corrosion Inhibitor for Corrosion Under Insulation (CUI) Protection

Protech Global Ltd has formulated a unique corrosion inhibitor for the protection of steel pipe surfaces from corrosion under insulation(CUI). Designed to be installed directly onto the surface of pipes fitted with insulation materials, Margel VPI 595CUI® corrosion inhibitor is a mid to long term fit and forget cost effective solution to the problems of corrosion under insulation(CUI) in industry the world over. Margel VPI 595CUI® is formulated for use in temperatures from -55 ºC to +25ºC, with this upper temperature limit currently bearing witness to stringent scientific test.

Margel VPI 595CUI® corrosion inhibitor for corrosion under insulation(CUI), in liquid or patch form, works by emitting a controlled amount of corrosion inhibiting vapour that when applied to steel surfaces, disperses and is absorbed by its substrate, blocking the path of chlorides, water and oxygen. Margel VPI 595CUI® corrosion under insulation(CUI) is manufactured with organic compounds and forms a monomolecular layer onto the surface of steel, this eliminates any further corrosion, working equally well on both newly manufactured or already corroded steel products.

Margel VPI 595CUI® corrosion inhibitor for corrosion under insulation(CUI) migrates up to 2mtrs from its placement location, which is dependent on environmental condition, and will start working from the moment it is applied, typically eliminating further corrosion activity as soon as14 days from application. ProTech Global have a portfolio of projects where Margel® is still working 25 years from application. Margel® variants have to date been applied to more than 2000 projects worldwide.

Margel VPI 595CUI® corrosion inhibitor for corrosion under insulation(CUI) is unaffected by damp/humid environments and works best in hermetically sealed environment to prolong the effectiveness. This can be achieved by sealing with a suitable enclosure system such as ProTech Global’s Proclad150™️ or Proclad350 PLUS™️.

Margel VPI 595CUI® Information

Application

Margel VPI 595CUI® corrosion inhibitor for corrosion under insulation(CUI) should be applied within the vicinity of the steel to be protected. Product should be applied as per the indicated consumption rate(above) directly to the steel surface. Once applied Margel VPI 595CUI® for corrosion under insulation(CUI) it is preferable to have low air movement where the product is placed to avoid loss of vapour pressure and to ensure continued concentration of the vapours to migrate and coat the steel surfaces. If water ingress is anticipated at time of application, then care should be taken to apply Margel VPI 595CUI® for corrosion under insulation(CUI) on the upper side of the intended surface to avoid sitting in pooling water. Water will not affect the properties of the corrosion inhibitor but may impact the migration of vapour and if significant reduce the effective life of the Margel Margel VPI 595CUI® for corrosion under insulation(CUI) product.

Surface Preparation

Margel VPI 595CUI® corrosion inhibitor for corrosion under insulation(CUI) requires no preparation of the steel surface to be protected. It works equally well on both newly manufactured steel as well as corroded steel surfaces.

Coverage Rate

ProTech Global recommends a coverage rate for Margel VPI 595CUI® for corrosion under insulation(CUI) of 2 patches per m² or 15ml measure of liquid per m² (minimum)

Protech Global Ltd will provide advice on a per project basis to determine long term effective protection.

Alternative Products

Margel VPI 600CUF® gel corrosion inhibitor is formulated for use on pipelines with operating temperatures up to 180ºC. This product is designed for steel products without insulation.

Margel 600CUF

Margel® VPI 600CUF®

Corrosion Inhibitor Under Fireproofing

Protech Global Ltd has formulated a unique corrosion inhibitor for the protection of steel surfaces that may suffer from corrosion under fireproofing (CUF).

Corrosion under fireproofing(CUF) is a specific recognised issue that is estimated to cost hundreds of billions of dollars every year, corrosion under insulation (CUI) and corrosion under fireproofing (CUF) are a common challenge across the power generation, refining, chemical, and other industrial sectors. When it comes to corrosion under insulation(CUI), corrosion under fireproofing(CUF) or corrosion under coatings, most contributing factors are extremely difficult or impossible to control. The power of prevention comes from regular inspection and preventive maintenance.

Corrosion under insulation(CUI) and corrosion under fireproofing(CUF) occurs as a result of moisture penetration and warm temperatures in pipework, vessels and other insulated assets. It often takes the form of general corrosion. Both corrosion under insulation(CUI) and corrosion under fireproofing(CUF) are difficult to detect as they are hidden by the protective layers and likely only found when insulation or fireproofing is removed for visual inspection or when a leak occurs, unless an advanced non-destructive testing (NDT) method is used. Corrosion under fireproofing is said to be responsible for the highest occurrence of leaks in the chemical and refining sectors.

Margel VPI 600CUF® corrosion inhibitor for corrosion under fireproofing(CUF) is uniquely formulated to be applied as a liquid/gel format for easy insertion behind fireproofed coverings. The twin-pack system utilises static mixer nozzles that evenly mix the components in a 1:1 ratio allowing injection into holes of diameter 10mm. Once applied the gel will flow behind the fire protection and then quickly set to a solid. Margel VPI 600CUF® is formulated for use in temperatures from -40ºC to +65ºC. Application temperature is from -5ºC to +30ºC.

Margel VPI 600CUF® corrosion inhibitor for corrosion under fireproofing(CUF) works by emitting corrosion inhibiting vapour that adsorbs onto steel surfaces blocking the path of chlorides, water and oxygen. Margel VPI 600CUF® is based on organic compounds and forms a monomolecular layer on the surface of steel. This eliminates any further corrosion working equally well on both corroded steel and new un-corroded steel surfaces. Margel VPI 600CUF® corrosion inhibitor will migrate up to 1metre from its placement location and depending on application temperature, will start working from the time it is applied and will typically eliminate further corrosion activity within 14 days from application.

Protech Global Ltd have projects where Margel® variants are still working 25 years from application. Margel® variants have been applied to over 4000 projects worldwide.
