Corrosion Monitoring Guide: Coupons, Probes & EIS

Corrosion Monitoring Guide: Coupons, Probes & EIS

Short answer: Corrosion monitoring tracks metal loss in service with weight-loss coupons, linear-polarisation resistance and electrochemical impedance probes, electrical-resistance probes and field surveys — turning unknown degradation into a managed rate and remaining life.

Why Monitor Corrosion

You cannot manage what you cannot measure: monitoring converts unknown loss into a rate you can budget against. The maths behind rates is in Metal Corrosion Rate Calculation Guide; the lab methods in Metal Corrosion Testing Guide; the chemistry in Metal Corrosion Inhibitor Guide.

The Toolbox

Coupons give an absolute baseline (mpy/mmy); LPR and EIS give online rate and mechanism (coating health); ER probes accumulate loss remotely; field surveys map hot spots. Pair with Metal Ndt Guide ve Cathodic Protection Guide; design margin via Metal Corrosion Allowance Guide.

Action & Supply

When the rate climbs, adjust inhibitor, inspect (Metal Failure Analysis Guide) and re-order stock documented per Mill Test Certificate Guide. HXSCO supplies corrosion-selected grades so your monitoring stays in budget.

Sıkça Sorulan Sorular

What is corrosion monitoring?

Measuring metal loss in service to turn unknown degradation into a managed rate and remaining life.

What is an LPR probe?

A linear-polarisation-resistance probe that reports corrosion rate online from a small polarisation scan.

What does EIS tell you?

Electrochemical impedance spectroscopy reveals the corrosion mechanism and coating barrier health.

Why use weight-loss coupons?

They give an absolute, simple baseline rate (mpy/mmy) that validates the electrical methods.

Do you supply corrosion-selected stock?

HXSCO supplies grades selected so your monitored corrosion rate stays within budget.
