Drewgard: A Legacy of Corrosion Protection in Environmental & Water Treatment
This chapter delves into the specific techniques employed by Drewgard to combat corrosion in various applications.
Corrosion Inhibition Mechanisms:
Drewgard products utilize a variety of mechanisms to prevent corrosion, including:
- Passivation: This involves forming a protective layer on the metal surface, preventing further interaction with the corrosive environment. Drewgard inhibitors often contain compounds that react with the metal to create this protective layer.
- Cathodic Protection: This technique uses an external electrical current to counteract the corrosion process. Drewgard offers specialized products for cathodic protection systems, particularly in marine environments.
- Oxygen Scavenging: Oxygen is a major contributor to corrosion in many systems. Drewgard products can remove dissolved oxygen from water, reducing the potential for corrosion.
- Filming: Some Drewgard inhibitors form a thin film on the metal surface, acting as a physical barrier to prevent corrosion. These films can be organic or inorganic, depending on the application.
- Chemical Adsorption: Certain Drewgard inhibitors adsorb onto the metal surface, preventing corrosive agents from reaching the metal. This mechanism is particularly effective in reducing corrosion in high-temperature or acidic environments.
Specific Techniques for Different Industries:
- Industrial Water Treatment: Drewgard utilizes techniques like passivation and oxygen scavenging to protect boilers, cooling systems, and heat exchangers.
- Oil and Gas: Drewgard focuses on techniques like cathodic protection and filming to safeguard pipelines, drilling equipment, and production facilities.
- Marine & Offshore: Drewgard employs a combination of passivation, cathodic protection, and specialized coatings for corrosion control in harsh marine environments.
- Power Generation: Drewgard utilizes both chemical and electrochemical methods to protect turbines, condensers, and other critical components in power plants.
