Corrosion Coupons
Corrosion of equipment or pipeline would cause enormous costs to the companies in the industries of oil&gas, petrochemical, water treatment, chemical and pharmaceutical, etc. as measured in equipment maintenance and replacement. The corrosion monitoring equipments manufactured by Shenyang EMT could help the companies to monitor the corrosion status to get the necessary data for taking effective measures to control the corrosion.

Corrosion Coupons are used for studying the corrosion status in pipelines or vessels by observing the metal loss of the coupons. Usually, the chemical composition of the material of corrosion coupons is the same as or similar to the material of the pipelines or vessels which are going to be monitored.
