Understanding and Mitigating Corrosion in Pump Environments

Category: All Industries, Pump

Corrosion is a persistent and often silent adversary that plagues global industrial environments. Corrosion can be defined as the deterioration of materials due to chemical reactions with their surroundings. It poses significant challenges in pumps and other essential related machinery. From compromising structural integrity to escalating maintenance costs, the implications of corrosion are vast and complex and missing it in systems often results in costly repairs.

Chemical reactions, environmental conditions, and material properties cause corrosion in industrial environments. Chemical reactions between metals and corrosive agents play a pivotal role, initiating processes that gradually break down the materials. Environmental factors such as humidity, temperature, and pollutants can accelerate corrosion, while the inherent properties of materials, such as their composition and microstructure, also influence susceptibility.

Understanding the various types of corrosion is crucial for effective mitigation strategies. Uniform corrosion, the most common type, occurs evenly across a material’s surface. Pitting corrosion involves localised damage, while crevice corrosion occurs in confined spaces. Galvanic corrosion arises when dissimilar metals come into contact, creating a corrosive cell. Stress corrosion cracking is a specific form induced by the combination of tensile stress and corrosive environments. Any of these can wreak havoc in pump systems and industrial environments.

The repercussions of corrosion extend beyond mere material degradation. Economically, corrosion leads to increased maintenance costs, repair expenses, and potential production downtime. Safety is compromised as corroded structures may fail unexpectedly. Environmental impacts arise from releasing degraded materials into systems and beyond into local ecosystems. The collective consequences emphasise the need for comprehensive corrosion management strategies.

Efficient corrosion management involves a multifaceted approach. Material selection with corrosion resistance can be a factor for new pumps; however, corrosion-resistant surface coatings are the primary corrosion prevention measure for established systems. Industrial-quality coatings provide a layer of defence to shield materials from degradation and corrosion in many environments. Regular monitoring and maintenance routines are also crucial for early detection and intervention.
