Description of Corrosion Coupon Holders
A corrosion coupon holder is a device used in corrosion monitoring to securely hold corrosion coupons in a specific location within a system. They are small metal samples that are exposed to the operating conditions of a system to assess the rate and type of corrosion occurring.
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.
