Having worked across the length and breadth of the energy, power, oil and gas and telecom sectors, our engineers and technicians are well-aware of the corrosion failures. To prevent the deterioration and loss of materials and their critical properties due to chemical, electrochemical and other reactions, we manage a team of qualified, certified and expert engineers and workers/craftsmen.
Our operating procedures follow the standards NACE (National Association of Corrosion Engineers), SSPC (The Society for Protective Coatings), and ISO (International Organization for Standardization). The corrosion inspectors at our company are NACE certified with Level 1 and Level 2 certifications.
We have prepared surfaces ranging from steel, concrete, wood, plastic and aluminum. Done mechanically or chemically, the processes employed are grits, shots, or abrasive blasting. It is widely known that abrasive blasting cleaning is the most thorough and widely used method of surface preparation in the shipbuilding and repair industry. This is by far the most effective method for removal of mill scale, rust and old coatings using abrasives such as sand, grit, or shots under high pressure.
Our certified inspectors carefully inspect surfaces for any pre-existing coatings, surface imperfections, residue, organic matter, oxidation and other contaminants. Being experts in corrosion prevention, our teams make use of white blasting where an optimal protective coating performance is required due to severe conditions like continuous immersion in water or liquid chemicals. Near white metal blasting is used for cleaning metal surfaces with abrasives to prepare the surface for corrosion proofing by the application of paintings and coatings.
Next step is the coating application to the surface that has been prepared. The method of application is governed by the coating manufacturer’s recommendation for the particular coating being applied and our coating team is well-versed with the exact steps to follow. Our team strives to achieve a steady brush operation so that a smooth coat, as uniform in thickness as possible is obtained. Skips, runs, sags, and drips are avoided. Maximum attention is paid that each coat remains free of pinholes, blisters and holidays as well as contamination of painted surfaces between coats are avoided. Airless spraying is known to be the quickest and most effective method used for coating application in the industry and we have provisions for a wide variety of spray painting solutions.
HDG (Hot Dip Galvanizing) requires degreasing/caustic cleaning, pickling and fluxing as the initial surface preparation step. It is a critical step in the application of any coating otherwise the coating may fail before the end of its expected service life because of incorrect or inadequate surface preparation. We are proud to mention that MECC owns the biggest HDG (hot dip galvanizing) plant in the country with zinc baths of up to 30 feet. British standards to hot-dip galvanize mild steel with dry film thicknesses of 90-120 microns are adhered to.
During the actual galvanizing step of the process, the material is completely immersed in a bath of molten zinc. Once the fabricated item’s coating growth is complete, it is withdrawn slowly from the galvanizing bath and the excess zinc is removed by draining, vibrating or centrifuging. And finally the inspection phase is reached where the coating thickness and appearance/surface conditions are inspected to determine through simple physical tests the thickness, uniformity, adherence and appearance of the material.
MECC has been galvanizing various products/materials for many years according to long established, accepted and approved standards of the governing standardization bodies in this particular sector.
