One of the most practical preventive maintenance methods for minimizing or controlling corrosion in product pipelines, vessels, etc., is to treat the corrosive environment with chemical inhibitors. While corrosion inhibition is a complex technology and is under constant study and development, it is an effective means of corrosion control. Using the COSASCO® Injection System for easy, reliable access, inhibitors can be injected with safety and simplicity while under full operating pressure. In addition, a variety of injection devices and systems can be used to provide the most efficient delivery and dispersion for a given application. Most of the parts involved in the COSASCO® Injection System are interchangeable with the COSASCO® Sampling System. The COSASCO® Sampling System offers a means of extracting samples from pipelines or vessels while under full system operating pressure. A typical COSASCO® Injection System with various injection dispersion ends and components is shown in the figure on the data sheet.
