Description

A corrosion coupon holder is a vital tool in the field of industrial maintenance and safety, playing a crucial role in the ongoing battle against corrosion in various industrial systems, such as pipelines, tanks, and boilers. These holders are designed to precisely position corrosion coupons—small, standardized pieces of metal representative of the system’s material—within the operational environment. By exposing these coupons to the same conditions as the rest of the system, they accumulate corrosive wear at a rate indicative of the system’s overall corrosion levels.

The data gathered from these exposed coupons, once analyzed, provides invaluable insights into the corrosion dynamics within the system, helping to predict potential failures and the lifespan of the infrastructure. This proactive approach allows for timely maintenance and replacements, thus avoiding unexpected downtimes and potentially catastrophic failures.

Furthermore, these devices are engineered to be easily retrievable, enabling regular inspections and replacements without major interruptions to system operations. Their design and placement within the system are critical to ensure that the coupons experience representative environmental conditions. As such, corrosion coupon holders are an indispensable component in a comprehensive corrosion management program, aiding industries in safeguarding their assets while optimizing maintenance strategies.

Types of Corrosion Coupon Holders

There are several types, including:

1. Disc Corrosion Coupon Holder: This holder is designed to fix a single disc-shaped corrosion coupon at a designated location.

2. Multiple Disc Corrosion Coupon Holder: This type of holder can accommodate multiple disc-shaped coupons, allowing for simultaneous monitoring at different locations.

3. Strip Corrosion Coupon Holder: Strip holders are used to securing rectangular strip coupons, which are particularly useful for monitoring corrosion along flat surfaces or in narrow spaces.

4. Ladder Strip Corrosion Coupon Holder: Similar to strip holders, ladder strip holders can hold multiple strip coupons arranged in a ladder-like configuration.

Materials of Corrosion Coupon Holders

Coupon holders are typically made from materials compatible with the system being monitored and can be customized to meet specific requirements. The most common and economical type of coupon holder is the fixed (pipe plug) coupon holder. These holders are easy to install and can be made from various materials. They are often used with bypass systems or can be threaded directly into process piping.
