CORROSION CONTROL

Comprehensive Corrosion Control Services by Entekra


Corrosion is a pervasive issue that can significantly impact the durability and safety of metal structures. At Entekra, we don’t just help you understand corrosion - we provide effective solutions to mitigate and prevent it. Our team of experts utilises advanced methods to address corrosion, ensuring that your structures remain strong, reliable, and protected for the long term.


What is Corrosion and Why Does it Matter?


Corrosion is the natural deterioration of metals caused by electrochemical reactions. Common examples include rust on iron, tarnish on silver, and the blue-green patina on copper. Left unchecked, corrosion can compromise structural integrity and lead to costly repairs or replacements.


In Australia, corrosion costs the economy over $100 billion annually, with more than 30% of these expenses deemed preventable through proper management and intervention.


Causes of Corrosion


Corrosion is triggered by interactions between metals and substances like oxygen, hydrogen, contaminants, and electrical currents. Additional factors such as stress, moisture, and temperature variations can accelerate the process, leading to:


  • Pitting Corrosion: Localised damage forming holes or cavities.
  • Crevice Corrosion: Occurs in areas with limited oxygen, like beneath washers or bolt heads.
  • Stress Corrosion Cracking: Cracks caused by tensile stress in a corrosive environment.
  • Galvanic Corrosion: When two dissimilar metals in contact corrode at different rates.

How Entekra Addresses Corrosion


At Entekra, we focus on proactive and effective solutions to combat corrosion at its source. Our comprehensive services include:


Wrapping Band Applications


Ideal for pipelines, beams, and other exposed metal surfaces, our wrapping band applications provide an additional protective layer to prevent exposure to corrosive elements.


Wet Spray Treatments


Using advanced wet spray techniques, we apply high-performance coatings that form a durable barrier against moisture, chemicals, and environmental stressors.


Casement Filling


We seal and protect critical areas, such as joints and voids, with corrosion-resistant materials to prevent water ingress and material degradation.


Surface Preparation and Coatings


We prepare surfaces using abrasive techniques and apply specialised coatings, including epoxy, polyurethane, and zinc-rich primers, to safeguard against wear and corrosion.

<span>01</span> WHAT IS CORROSION
<p class="rteBlock">Corrosion is commonly described as the deterioration of metals caused by an electrochemical reaction. Instances of corrosion include the development of rust on iron, tarnish on silver, and the emergence of a blue-green patina on copper.</p><br><p class="rteBlock">Corrosion has been said to cost the Australian economy upwards of $100 billion annually. More than 30% of these expenses could have been avoided.</p>
<span>02</span> CAUSES CORROSION
<p class="rteBlock">The corrosion of metal occurs as a result of interactions with different substances, such as oxygen, hydrogen, electrical currents, and even contaminants like dirt and bacteria. Corrosion can also be triggered when metals, like steel, are subjected to excessive stress, causing the material to develop cracks.</p>
<span>03</span> TYPES OF CORROSION ARE THERE
<ol class="rteBlock defaultList"><li>Uniform Corrosion</li><li>Pitting Corrosion</li><li>Crevice Corrosion</li><li>Intergranular Corrosion</li><li>Stress Corrosion Cracking (SCC)</li><li>Galvanic Corrosion</li></ol>
<span>04</span> UNIFORM CORROSION
<p class="rteBlock">This form of corrosion is the most frequently encountered, usually manifesting evenly across broad areas of a material&#x27;s surface.</p>
<span>05</span> PITTING CORROSION
<p class="rteBlock">One of the most aggressive forms of corrosion, pitting can be challenging to predict, detect, or characterise. This localised type of corrosion occurs when a specific anodic or cathodic point forms a corrosion cell with the surrounding surface. This pit can create a hole or cavity, typically penetrating the material vertically from the surface.</p><br><br><p class="rteBlock">Pitting corrosion can be caused by damage or a break in the oxide film or a protective coating. It can also result from non-uniformities in the structure of the metal. This hazardous form of corrosion can lead to a structure failing despite a relatively low loss of metal.</p>
<span>06</span> CREVICE CORROSION
<p class="rteBlock">This type of corrosion occurs in regions with limited oxygen, such as beneath washers or bolt heads. This localized corrosion typically arises from variations in ion concentration between two metal areas. The stagnant microenvironment hinders oxygen circulation, preventing re-passivation and leading to the accumulation of stagnant solution, shifting the pH balance away from neutral.</p><br><br><p class="rteBlock">The disparity between the crevice and the rest of the material contributes to elevated corrosion rates. Crevice corrosion can occur at lower temperatures than pitting corrosion but can be reduced through appropriate joint design.</p>
<span>07</span> INTERGRANULAR CORROSION
<p class="rteBlock">Intergranular corrosion arises when impurities are present at the grain boundaries formed during the solidification of an alloy. It can also result from the enrichment or depletion of an alloying element at these grain boundaries. This corrosion type occurs along or next to the grains, impacting the mechanical properties of the metal, even though the majority of the material remains unaffected.</p>
<span>08</span> STRESS CORROSION CRACKING
<p class="rteBlock">Stress corrosion cracking involves the expansion of cracks caused by a corrosive environment, potentially resulting in the failure of ductile metals under tensile stress, especially at elevated temperatures. This corrosion type is more prevalent in alloys than in pure metals and relies on the particular chemical environment, where only minimal concentrations of active chemicals are necessary for significant cracking.</p>
<span>09</span> GALVANIC CORROSION
<p class="rteBlock">This type of corrosion takes place when two distinct metals, in physical or electrical contact, are submerged in a shared electrolyte (like saltwater) or when a metal is exposed to varying electrolyte concentrations. In a galvanic couple, where two metals are immersed together, the more active metal (the anode) corrodes faster than the more noble metal (the cathode). The galvanic series dictates the relative corrosion rates of metals, making it valuable when employing a sacrificial anode to safeguard a structure from corrosion.</p>
<span>10</span> CORROSION CONTROL
<ul class="rteBlock defaultList"><li>Opt for non-corrosive metals, such as stainless steel or aluminum.</li><li>Ensure the metal surface remains clean and dry.</li><li>Utilise drying agents.</li><li>Apply a coating or barrier product, such as grease, oil, paint, or a carbon fiber coating.</li><li>Employ a layer of backfill, like limestone, alongside underground piping.</li><li>Implement a sacrificial anode for establishing a cathodic protection system.</li><li>Installing a wrapping band on the metal from pipes and beams to bridges and wind turbines.</li></ul>
<span>11</span> IMPORTANCE OF CORROSION PREVENTION
<p class="rteBlock">Effective corrosion management is a significant consideration for businesses dependent on metals, ensuring the optimal functioning of essential structures like bridges, reservoirs and pipelines.</p>
<span>12</span> HOW ENTEKRA CAN HELP
<p class="rteBlock">The main ways we can help are wrapping band applications, wet spray and casement filling.</p><br><br><p class="rteBlock">Entekra provides corrosion control on rooftops, bridges, reservoirs, pipelines, wind turbines, buildings and much more.</p>
