CORPS Provide Complete Corrosion Monitoring solutions.
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.
CORPS provides coupons in any size, shape, or material you need. Coupons can be stencilled with alloy and sequence numbers for proper identification. Mill test reports, identifying element compositions of materials used, are provided on all orders.
The electrical resistance (ER) technique is an “on-line” method of monitoring the rate of corrosion and the extent of total metal loss for any metallic equipment or structure. The ER technique measures the effects of both the electrochemical and the mechanical components of corrosion such as erosion or cavitation. It is the only on-line, instrumented technique applicable to virtually all types of corrosive environments.
Although universally applicable, the ER method is uniquely suited to corrosive environments having either poor or non-continuous electrolytes such as vapors, gases, soils, “wet” hydro-carbons, and nonaqueous liquids. Examples of situations where the ER approach is useful are:
• Oil/gas production and transmission systems
• Refinery/petrochemical process streams
• External surfaces of buried pipelines
• Feedwater systems
• Flue gas stacks
• Architectural structures
An ER monitoring system consists of an instrument connected to a probe. The instrument may be permanently installed to provide continuous information, or may be portable to gather periodic data from a number of locations. The probe is equipped with a sensing element having a composition similar to that of the process equipment of interest.
