Corrosion coupons are the simplest and most commonly used form of corrosion measurement today. Corrosion coupons are small bars of various metals or alloys that are introduced into the system through a side stream coupon rack. The coupon alloy selection should be representative of system metals.TEST METHOD 5 CORROSION TESTS Chapter 1. Uniform Corrosion General Description Test specimens (coupons) of each alloy to be tested, are engraved with a unique identification code, measured to determine dimensions, cleaned to remove grease and oxidation films, rinsed in distilled water and dried. Each coupon is weighed and immersed in a test coupon testing corrosion

How can the answer be improved?

A corrosion coupon is a simple and very effective tool that gives a quantitative estimate of corrosion rates that take place within a specific operating system. These coupons also offer a visual signal of the corrosion type that may be occurring in the system under observation. ASTM G4 Standard Guide for Conducting Corrosion Coupon Tests in Field Applications. Designation: G 4 95 Standard Guide for Conducting Corrosion Coupon Tests in Field Applications 1 This standard is issued under the fixed designation G 4; the number immediately following the designation indicates the year of original adoptioncoupon testing corrosion The technique requires no complex equipment or procedures, merely an appropriately shaped coupon, a carrier for the coupon (coupon holder), and a reliable means of removing corrosion product without disruption of the metal substrate.

Corrosion coupon testing is an inline monitoring technique; coupons are placed directly in the process stream and extracted for measurement. This monitoring technique provides a direct measurement of metal loss that allows you to calculatethe general corrosion rate. Also, when using corrosion coupons, your results are not dependent coupon testing corrosion G2MT Labs offers corrosion coupon monitoring and coupon testing services, including design, installation, removal, and analysis of coupons. Our singlephase flow loops and immersion testing systems are ideal for laboratory testing. Bypass rigs can be used to allow easy monitoring of corrosion within existing piping systems. We can analyze Corrosion coupon testing is an inline monitoring technique; coupons are placed directly in the process stream and extracted for measurement. This monitoring technique provides a direct measurement of metal Corrosion Coupons Accurate monitoring of corrosion rates in any environment is critical when viewed in terms of the maintenance and repair costs associated with corrosion and material failure. Test coupons provide an inexpensive means of online monitoring that will allow you to effectively measure the corrosivity within your Coupon testing remains a powerful tool in the corrosion engineer's tool kit. Intelligent and systematic use of this tool provides data which allows a knowledgeable and experienced engineer to make reliable predictions of field performance.
