Bulk items such as cast and forged valves are installed under various temperature conditions. It is exposed to a wide range of temperatures, therefore the coating product applied to bulk items should have appropriate heat resistance performance. However, it is very difficult to select a suitable coating system since the temperature condition is not determined in the valve manufacturing stage. For this reason, unsuitable coating systems are often applied, causing coating defects in the field operation. Therefore, it is necessary to apply a coating system that can cover a wide temperature range to prevent this problem.

In Oil & Gas facilities projects, coating system selection of bulk valves is challenging for EPC contractor to manage because their quantity is extensive and they are installed at each specific situation. IMM (Inert Multi Polymeric Matrix) / IC (Inorganic Copolymer) coatings, hereinafter referred to as IMM, which can be applied under various situations are anticipated to be applied for the bulk valves. Several types of IMM paints have been introduced to the market and corrosion protection performance were evaluated in this paper. Test panels of IMM coatings were prepared from five different manufacture’s brands, with variations in dry film thickness, hereinafter referred as DFT, (125µm/250µm) and with or without heat curing. Corrosion protection performance was tested by salt spray tests (720 hours, 1440 hours) and natural weathering tests (18 month), and evaluated by degree of rust, pull-off tests, and EIS (Electrochemical Impedance Spectroscopy) tests. The results of salt spray tests and natural weathering tests varied depending on each brand's product. The overall trend indicates that panels with a 250µm DFT and without heat curing panels demonstrates better corrosion protection performance rather than panels with a 125µm DFT and with heat curing. In the EIS test, some test panels showed a significant drop in impedance values at low frequency (0.1Hz) with heat curing, which may suggest a degradation in corrosion protection performance. In conclusion, it is recommended to use IMM coatings with a 250µm DFT and to be cautious when applying them at high temperature services.

Exploring The Truth About Aluminium Flakes As Pigments In Corrosion Protective Coatings

The success of corrosion protective coating systems relies, to a great extent, on the coatings’ inherent barrier properties. This barrier property signifies the coating’s ability to withstand the permeation of sea water and oxygen, thus minimizing corrosion of the underlying metal. While various additives or pigments can promote the barrier property of coatings, one of the most common pigments is aluminum flakes [1-4].The idea behind their use is simple, and essentially relies on having the aluminum flakes in the coating oriented parallel to the underlying substrate. With them in place, the pathways for sea water and oxygen effectively increase, thus preventing the progression of corrosion. However, while having been employed in numerous coating formulations for many years, the evidence for the success of aluminum flakes as barrier pigments is still lacking.

In new shipbuilding industries, conventional solvent-born coatings require longer curing period at low temperature season, which creates the needs for fast curing coatings to meet work schedule. In this study, several kinds of solvent free rapid cure epoxy coatings and polyurea coatings were evaluated in terms of feasibility for ship’s water ballast tanks (WBT).
