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.
Coupon insertion system is a retractable unit commonly used in field and plant applications. A specially designed packing gland is used to insert or retract a coupon from a pressurized system without a process shutdown.
