Corrosion rate standards are established benchmarks that define how fast metal deterioration is considered acceptable in industrial water systems. Expressed in mils per year (MPY) — thousandths of an inch per year of metal loss — these standards, set by the Association of Water Technologies (AWT), give water treatment professionals a measurable target to maintain, compare against, and report on. For mild steel, acceptable corrosion rates fall below 3.0 MPY; for copper and copper alloys, below 0.2 MPY. Rates above these thresholds signal a treatment program gap that requires immediate action.
We build corrosion monitoring programs around your system metallurgy, your water chemistry, and your compliance obligations — not a generic coupon kit dropped off quarterly. The right inhibitor, dosed correctly, monitored continuously. Corrosion rates stay within AWT benchmarks. Your infrastructure lasts longer. Your team stops reacting and starts preventing.

Standard AWT exposure period for statistically valid corrosion rate data
Most facilities reach benchmark corrosion rates within the first year of a managed program
Corrosion coupons are small metal samples — carbon steel, copper, admiralty brass — installed directly in your system water flow and retrieved on a 30–90 day AWT-compliant cycle. ChemREADY's field technicians install, retrieve, clean, and weigh every coupon to ASTM G01 protocol, then deliver an MPY report with benchmark comparison and program adjustment recommendations. You get real data, not assumptions.

High corrosion rates almost always trace back to an inhibitor program that is underdosed, mismatched to your metallurgy, or not being monitored for residual. ChemREADY engineers site-specific corrosion inhibitor programs — selecting the right chemistry for your metals, dosing to maintain a verified residual, and adjusting based on coupon data and inline monitoring results every service cycle.

Quarterly coupon pulls tell you what happened. Real-time monitoring tells you what is happening. ChemREADY's digital remote monitoring systems track pH, conductivity, inhibitor residual, and corrosion indicators continuously — alerting your team and ours the moment water chemistry drifts outside the corrosion control window, before it shows up in your next coupon result.

If you do not have current coupon data, you do not have a corrosion rate — you have a guess. ChemREADY's free water analysis establishes your baseline: pH, conductivity, hardness, alkalinity, inhibitor residual, and corrosion indicator testing across your system. From that baseline, we build a benchmarked corrosion monitoring program sized to your infrastructure and your compliance requirements.
Read More →Every high corrosion rate has a source — and the wrong inhibitor chemistry makes it worse. Our program starts with identifying exactly what is driving metal loss in your system, then deploys the right treatment at the right point, monitored continuously so it stays solved.
Before any program recommendation, we establish where your system actually stands. ChemREADY's baseline analysis covers pH, conductivity, dissolved oxygen, chloride levels, inhibitor residual, hardness, alkalinity, and total dissolved solids — mapped against your system metallurgy to identify which metals are at greatest risk and at what rate corrosion is currently occurring.
Coupons are selected by metal type to match your system components, installed per AWT rack specifications, and retrieved on a 30–90 day cycle. Every coupon is cleaned per ASTM G01 protocol, weighed to four decimal places, and reported with an MPY value and AWT benchmark comparison. No coupon kit programs — field technician installation and retrieval on every cycle.
Corrosion inhibitor chemistry is selected based on your system metals, water chemistry, operating temperature, and cycles of concentration — not a generic off-the-shelf product. ChemREADY engineers the correct inhibitor type (phosphonate, molybdate, azole, or blended), dosing rate, and application point to form a consistent protective film across all metal surfaces in the system.
pH below 7.0 and elevated dissolved oxygen are the two most common accelerants of electrochemical corrosion. ChemREADY's program establishes pH targets appropriate for your metallurgy (typically 7.5–9.0), installs automated pH control where needed, and manages dissolved oxygen through chemical oxygen scavengers or physical degassing, depending on system type.
Biological activity accelerates localized corrosion by creating differential oxygen cells and producing corrosive metabolic byproducts. ChemREADY's biocide program — oxidizing and non-oxidizing on a rotating schedule — controls the microbial populations that drive MIC, integrated into the broader corrosion control program so chemistry decisions do not conflict.
Running cycles of concentration too high concentrates chlorides, hardness, and dissolved solids beyond what the inhibitor program can manage — directly elevating corrosion rates. ChemREADY establishes the correct CoC target for your system, controls blowdown automatically where possible, and tracks CoC data at every service visit to ensure chemistry stays within the program design window.
ChemREADY's digital remote monitoring systems track pH, conductivity, inhibitor residual, and corrosion-driving parameters continuously. Automated dosing controllers maintain inhibitor residual within specification between service visits. Alerts notify ChemREADY field staff and your operations team the moment a parameter drifts outside the corrosion control window.
ChemREADY field technicians conduct on-site service visits on a documented schedule — testing water chemistry, reviewing coupon data, inspecting system components for corrosion evidence, and updating your water management program log. Every visit produces a written service report with current MPY values, AWT benchmark status, chemical program adjustments, and corrective action documentation.
Unmonitored corrosion does not announce itself. It shows up as a failed heat exchanger, a pipe leak during production, or a compliance notice after an inspection. By the time you see the damage, you have already paid for it — in emergency repairs, unplanned downtime, and reduced equipment service life.
ChemREADY’s managed corrosion control programs keep your metal loss rates within AWT benchmarks year-round, with documented MPY data at every service cycle so you have a defensible record for any audit, insurance review, or regulatory inquiry.
The result: longer equipment life, lower maintenance costs, and a corrosion rate you can actually stand behind when someone asks.
