Combating Marine Corrosion

Image
  Combating Marine Corrosion A distinguishing feature of the marine environment is the universally present high salt content in the air and seawater which acts as a catalyst for the corrosion of offshore structures, such as offshore oil rigs, Intake Pump Houses in Thermal Power Plants Handling Sea Water. Corrosion damage in these environments is also influenced by the presence of other chemicals and various pollutants in the seawater, air and ports and many other areas. The corrosive forces inherent in marine environments pose significant threats to the integrity and longevity of metal structures. In this technical blog, we explore the complexities of corrosion, its detrimental effects, and the imperative role of corrosion protection strategies using Kirloskar Corrocoat in safeguarding marine assets. Understanding Corrosion: corrosion refers to the natural process of deterioration that occurs when metallic structures, components, or equipment are exposed to the harsh conditions pre...

Pipeline Coating Technology

Image
  Pipeline Coating Technology Pipelines are the lifelines of various industries, transporting essential resources across vast distances. From oil and gas to water and chemicals, these vital arteries ensure the smooth operation of our modern world. However, the constant flow of fluids and exposure to harsh environments can take their toll on pipelines. Corrosion, abrasion, and erosion are major threats that can lead to costly repairs, downtime, and even safety hazards. With decades of experience protecting hundreds of kilometres of pipelines each year, Kirloskar Corrocoat Private Limited, along with technology partner Corrocoat Ltd., has developed specialized coating techniques for pipeline internal coating starting from pipe diameters of 3 inches and onwards and external surfaces with no limitation. Kirloskar Corrocoat Private Limited (KCPL) offers effective solution with polyester, epoxy and vinyl ester  glass flake coating  for  pipeline internal & external coa...

Antifouling Coating

Image
  Antifouling Coating Introduction: In maritime industries, combating fouling of submerged structures, pipes, and equipment is a persistent challenge. Fouling, the undesirable accumulation of materials on surfaces, significantly impairs efficiency and functionality. Whether originating from biological or non-biological sources, fouling poses a serious problem. The Kirloskar Corrocoat's  Biofoul  is an advanced  anti-foul coating  designed to combat the detrimental effects of biofouling in both sea water and freshwater environments. The Historical Solution: Centuries ago, mariners utilized copper sheeting to protect their wooden vessels from fouling. The copper-rich surface effectively deterred fouling agents. Bio foul employs a similar mechanism, presenting a copper-rich surface that deters fouling agents. Unparalleled Durability and Resistance: Unlike conventional anti-foul materials, Biofoul forms a robust and durable surface that withstands scuffing and high-...

Pitting Corrosion

Image
  Pitting Corrosion What is Pitting Corrosion? “Pitting Corrosion” is the formation of holes in an otherwise relatively un-attacked surface. It is a form of localised corrosion that proceeds because of local cell action which produces cavities beginning at the surface. The cavities may or may not become filled with corrosion products. Corrosion products may form “caps” over the pit cavities which are described as “nodules” or “tubercules”. While the shapes of pits vary widely, they are usually rough saucer shaped, conical or hemispherical. Pitting corrosion is quite common. It can occur on a metal surface because of localised differences in composition or surface contamination, deposition or incorporation of metallic and non-metallic particles, or contact with dissimilar metal. This type of attack can by caused by a break in a protective film on the metal surface, such as an inhibitor film, oxide film or break in coating. It also may be caused by the uneven deposition of solids (me...

Look at Our Anti-corrosion Technology

  Look at Our Anti-corrosion Technology Corrosion affects everybody in one way or another. Monuments, structures, and products are a small percentage of infrastructure affected by the damage of corrosion. If corroded objects are left untreated, noticeable effects can start being present within the human body including: Harm to the digestive tract Skin and eye irritation Respiratory damage If we look at pure monetary terms, the cost of corrosion is estimated at between 3% and 6% of gross domestic product, amounting to a worldwide figure of 1409 billion dollars. Corrosion protection saves not only time and money but avoids many other problems including adverse publicity following corrosion-related incidents and/or loss of production. How Do Our Anti – Corrosion Coatings Work? Our coatings use glass flake fillers which are impermeable to increase considerably the diffusion path through the coating. This produces a barrier layer slowing moisture diffusion and the corrosion potential to...

Coating Application Techniques

Image
  Applying Coating Correctly: Successful application of protective coatings is pivotal to ensuring infrastructures receiving coatings withstand potential corrosion. There are several detrimental factors to consider if the coating is applied incorrectly and corrosion does occur. Some factors may include: Bodily harm including irritation and respiratory damage Loss of production with machinery being inoperable Financial strain with replacements or repairs Adverse incidents in public locations Loss in revenue with downtime Spray Techniques: Hand- Striping An important first step when applying a coating correctly is hand-striping. Before the first general coat is applied it is recommended to complete an extra spray pass or stripe coat. This coats all edges, corners, joints, and other irregular surfaces to ensure all surfaces are ready for the first coat and an adequate film can develop. Cross-layer application Applicators often spray coatings with a horizontal pass first which unfortun...
