Corrosion is defined as a refined metal that is naturally converted to a more stable form such as its hydroxide or sulphide state. Metal corrodes when it reacts with another substance such as oxygen, hydrogen or bacteria. Corrosion can also happen when metals are placed under too much stress causing the material to crack. Corrosion leads to deterioration of the material.
Stainless steel is highly corrosion resistant, making it suitable for use in environments where exposure to moisture, chemicals, or harsh conditions such as salt water is expected.
In this section you can find newsitems related to all types of corrosion such as stress corrosion cracking, intergranular corrosion, pitting, and corrosion fatigue. If you wish to include your news release on our website and email newsletter, please feel free to contact the editor.
A breakthrough in steel belt processing technology has enabled Sandvik Process Systems, a product area within Sandvik Materials Technology, to launch a range of super thin stainless steel conveyor belts.
With the help of Leading Edge (Canada) BC’s patenting and business development expertise, Surrey-based VK Tanks & Silos Inc. is entering into its first international contract to build four industrial wastewater tanks in New Jersey, USA.
The model 1951 Plunger pump has been introduced by CAT Pumps (USA) specifically to pump liquid carbon dioxide, with the growth of CO2 use in refrigeration systems.
The new Series 1740 Mk IV padlock from Camlock Systems (UK) is fitted with a re-programmable âeight locks in oneâ? octagon radial pin tumbler mechanism providing maximum protection against the un-authorised duplication of keys.
Circor Gyrolok tube fittings and Hoke ball and needle valves from Circor Instrumentation (UK) in a special combination of Monel and stainless steel were selected by Anatrol (UK) for its seawater analysis system.
Orbimatic, Germany, is assisting ADMS Engineering in the use of stainless steel
tubing for heating, cooling and ventilation systems. The use of stainless steel pipe offers some advantages over other materials, but it also offers other benefits which are not normally realised at the front end design stage.
Corrosion can be a big problem because it can cause significant damage and deterioration to various materials, particularly metals. We have listed below several reasons why corrosion is a significant concern:
Structural Integrity: Corrosion weakens the structural integrity of materials. When metals corrode, they lose their strength and load-bearing capacity, which can lead to failures and collapses in infrastructure, buildings, bridges, pipelines, and other critical structures.
Economic Impact: Corrosion imposes substantial economic costs. The direct expenses associated with corrosion include repairs, replacements, and maintenance of corroded structures and equipment. Additionally, there are indirect costs such as production losses, decreased efficiency, and increased energy consumption due to the effects of corrosion on industrial processes and machinery.
Environmental Consequences: Corrosion can have adverse environmental effects. For example, in the case of pipelines, corrosion can lead to leaks and spills of hazardous substances, causing soil and water pollution and damaging ecosystems.
Health and Safety Risks: Corrosion can create health and safety risks in various ways. For instance, when corrosion affects pipelines or storage tanks carrying toxic substances, it can lead to leaks or releases that endanger the health of workers, communities, and the environment.
Maintenance and Downtime: Corrosion necessitates regular maintenance and inspection programs to detect and mitigate its effects. This requires significant time, effort, and financial resources. Additionally, when corrosion-related issues arise, it often requires shutting down operations, causing downtime and productivity losses.
Given these reasons, it is crucial to understand and address corrosion through preventive measures, protective coatings, corrosion-resistant materials, regular inspections and testing (ASTM B117), and appropriate maintenance practices to mitigate its impact and ensure the longevity and safety of structures and equipment.
