About Corrosion
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 on-line monitoring that will allow you to effectively measure the corrosivity within your system. By observing the mils-per-year corrosion rate of an exposed coupon, valuable information can be provided regarding the material's life expectancy.
Corrosion and erosion monitoring coupons are specially made for corrosion and erosion studies and are manufactured to the most demanding standards. Generally, corrosion coupons should be of an alloy the same as, or similar in chemical composition to the pipeline or vessel that is being monitored.
Coupon Materials Available
The following materials are available as corrosion coupons:

Key Features
- Standard 4" x ½" size
- Pre weighed to 0.1mg
- Individually packed in sealed heavy duty polythene bags
- Fixing hole as required
The coupons used in field test are generally 4” x ½” as these fit in corrosion test racks. The ASTM D-2688 standard, entitled “Corrosivity of Water in the absence of Heat Transfer (Weight Loss Methods)” gives much useful information regarding the corrosion testing of water.
Corrosion test racks by-pass rigs are designed to permit easy and inexpensive monitoring of corrosion within water systems. Part of the water is diverted from the main flow into the By-Pass rig where it passes over test coupons and is then returned to the system.
The test coupons can be removed from the rack without the need to close down the system.
Built to ASTM standard D-2688, with a flow rate of 0.6 to 1.8m/s. Accepta's corrosion coupon test racks have a serpentine shape allowing the water to flow along each coupon from the holder in the same direction.
Applications: Oil & Gas, Pulp & Paper, Chemical, Petrochemical, Water treatment, Fume treatment, Mining, Shipbuilding, Power generation.
