Corrosion coupon monitoring – and overview
Steel loss coupons include the introduction of a sample that is weighed of alloy of interest to the procedure fluid, corrosion coupon monitoring and making the sample confronted with the process fluid for the known duration of time (usually 20-90 days, depending on the corrosion that is anticipated).
The sample will be removed from the system, cleaned of any corrosion that is recurring, and re-weighed. The weight-loss that is measured along with knowledge of the geometry that is entire with sample, permits the total depth loss more than a known time period become determined, along with this the typical corrosion rate is determined.
The method is simple, simple, and relatively inexpensive. Also, it shall, by comparison with traditional assessment methods, produce information reasonably quickly, and will work in nearly every pair of procedure conditions. Consequently, it’s the most widely used way of corrosion monitoring in use at present.
Equipment for corrosion monitoring:
- CORROSION COUPONS
- COUPON HOLDERS
- ACCESS FITTINGS
- RETRIEVAL TOOLS & SERVICE VALVES
