Corrosion Coupon Study & Applications

Reliable, low-cost monitoring of corrosive environments using customized coupons, rapid turnarounds, and expert interpretation to enhance operational efficiency.

Overview

Cost-effective monitoring of corrosive environments

Corrosion coupons provide an inexpensive means of on-line monitoring to measure system corrosivity and estimate material life via mils-per-year (mpy) or metal loss metrics.

ISO/IEC 17025:2017 accredited analysis with decision-ready interpretation.
Why coupon studies

Actionable data to manage risk & optimize maintenance

Maintenance and repair costs demand accurate monitoring of the corrosive environment. Observing mpy on exposed coupons yields valuable insights on life expectancy and informs mitigation plans and maintenance windows.

How it works

Classical weight-loss method—simple and proven

A weighed coupon of the target metal/alloy is introduced into the process and later removed after a defined interval, cleaned of corrosion products, and reweighed. The weight loss converts to corrosion rate or metal loss—no complex equipment required.

Acquire

Workflow

Procurement & process flow

We analyze corrosion coupons on a per-batch basis with customized options relevant to your requirements and provide results within days of receiving samples.

Customization

Coupon types & made-to-order configurations

Choose from a wide range of geometries—strip, disc, flush, cylindrical, weld, stress, coated/lined, cladded, notch, elastomer, impact, mesh, tensile, glass, grit, lap, mill/sand—and more. Sizes, shapes, and materials are fully customizable; stencilling of alloy and sequence numbers ensures traceability, and mill test reports provide elemental composition.
