Corrosion monitoring is the real-time or near-real-time measurement of metal loss, corrosion rate, and environmental conditions in process equipment and pipelines. It is distinct from periodic inspection, which captures only point-in-time snapshots. Real-time monitoring ensures that corrosion rates remain within acceptable ranges to meet designed service life targets. PMC \u2014 Corrosion Sensors for Structural Health Monitoring<\/a>.<\/p>\r\n Effective corrosion monitoring programs enable operators to detect accelerating corrosion before it reaches actionable thresholds. Proactive monitoring directly reduces failure risk and revenue loss. Unplanned downtime costs oil and gas facilities nearly $500,000 per hour<\/a>, and the global cost of corrosion is estimated at $2.5 trillion annually or 3.4% of global GDP<\/a>, according to the NACE IMPACT study.<\/p>\r\n Corrosion monitoring ensures structural integrity and prevents catastrophic failures in oil, gas, and hazardous liquid infrastructure. It acts as the backbone of regulatory compliance by validating that operators identify, measure, and mitigate internal and external corrosion. There are several regulatory bodies that provide standards for corrosion monitoring.<\/p>\r\n The Pipeline and Hazardous Materials Safety Administration (PHMSA) provides Federal pipeline safety regulations that state operators must conduct external corrosion monitoring at least once every three years and internal corrosion monitoring using coupons at least twice a year.<\/p>\r\n The National Association of Corrosion Engineers (NACE) provides safety guidelines based on predictive maintenance conditions for corrosion monitoring using pre-assessment modeling rather than timelines. NACE recommends internal corrosion testing in highly corrosive environments on a monthly to bi-monthly schedule. The American Petroleum Institute (API) recommends internal corrosion testing at least two times each year and external corrosion testing of rectifiers and cathodic protection devices at least six times a calendar year.<\/p>\r\n SMARTCORR\u00ae provides an integrated monitoring ecosystem, combining coupons, Electrical Resistance (ER) probes, Linear Polarization Resistance (LPR) probes, access fittings, and data loggers, as a unified approach that eliminates data silos between standalone monitoring technologies.<\/p>\r\n <\/p>\r\n The five primary corrosion monitoring methods are weight loss coupons, ER probes, LPR probes, Ultrasonic Thickness (UT) sensors, electrochemical monitoring, and hydrogen probes. Each has a specific application.Weight loss coupons provide cumulative corrosion data over weeks or months, while ER probes offer trend data over hours to days<\/a> with far shorter response times than coupons. LPR probes deliver instantaneous corrosion rate readings, as do UT sensors, electrochemical monitoring, and hydrogen probes.<\/p>\r\n Corrosion Monitoring Systems<\/p>\r\n SMARTCORR\u2019s\u00ae corrosion monitoring technology offers all three intrusive technologies, corrosion coupons, In the oil and gas industry, the choice between intrusive and non-intrusive monitoring equipment depends on fluid corrosiveness, system pressure and temperature, downtime costs, and safety risks. These factors dictate whether sensors can be mounted externally or must be inserted directly into the process stream.<\/p>\r\n Intrusive techniques<\/a> involve monitoring by penetrating through the interior of the pipe or vessel, while nonintrusive techniques monitor from outside the pipe or vessel wall without gaining access to the interior. Intrusive methods provide direct corrosion rate data in the actual operating environment, while non-intrusive methods avoid process penetrations but lack direct corrosive-environment exposure data.<\/p>\r\n Fittings, coupon holders, service valves, and retrieval tools form the mechanical backbone of any intrusive monitoring program enabling probe insertion and removal without process shutdown. These access fittings work to create a pressure-balanced closed-loop environment to safely install, inspect, and replace coupons, sensors, and probes under live operating pressure. Effective internal corrosion management requires integrating corrosion coupons<\/a>, ER probes, and LPR techniques, complemented by non-intrusive inspection, such as guided ultrasonics.<\/p>\r\n SMARTCORR\u2019s\u00ae access fittings<\/a> are rated to 6,000 psi\u201310,000 psi and feature a unique retrofit-compatible design, which allows operators to add monitoring points to existing infrastructure without costly shutdowns or process modifications.<\/p>\r\n Data architecture connects field-level sensors, such as probes, coupons, and transmitters, through data loggers and transmitters to centralized software platforms. This is how the pipeline transforms raw measurements into actionable corrosion rate trends, remaining life predictions, and automated alerts.<\/p>\r\n The corrosion monitoring market was valued at approximately $388 million in 2025<\/a> and is growing at a Compound Annual Growth Rate (CAGR) of 6.8%, reflecting increasing demand for integrated data solutions. Modern corrosion monitoring technology helps operators to transition from reactive maintenance to data-driven, predictive strategies.<\/p>\r\n SMARTCORR\u2019s\u00ae proprietary SCEMS software<\/a> is a platform that integrates ER probes, coupons, UT sensors, chemical sampling, and cathodic protection monitoring into a single interface with Carbon Dioxide and Hydrogen Sulphide (CO\u2082\/H\u2082S) corrosion prediction modules. This platform bridges the gap between monitoring hardware and predictive analytics in one corrosion monitoring system. To learn more, review our Harnessing Real-Time Corrosion Data<\/a> educational white paper.<\/p>\r\n Wireless-enabled corrosion transmitters eliminate the need for hardwired signal cables to remote monitoring points. Wireless transmitters result in a significant reduction in installation costs compared with wired online systems and allow for monitoring in previously inaccessible areas. These unique corrosion sensors enable deployment on offshore platforms, remote wellheads, and buried pipeline segments.<\/p>\r\n Real-time corrosion data from field assets is supported by industrial mesh networks, such as WirelessHART, low-power wide-area cellular networks, such as LTE-M and NB-IoT, and satellite constellations, such as Iridium and Inmarsat. These protocols transmit data to cloud-based monitoring platforms or Supervisory Control and Data Acquisition (SCADA) systems for continuous integrity management.<\/p>\r\n While wireless monitoring expands coverage, operators must evaluate signal reliability in process environments with electromagnetic interference, explosive atmospheres requiring ATEX\/IECEx certification, and power supply constraints for battery-operated transmitters.<\/p>\r\n SMARTCORR\u2019s\u00ae remote data loggers feature a minimum 1-second data log interval with the ability to integrate with existing telemetry infrastructure, enabling operators to connect monitoring hardware to SCEMS software regardless of site connectivity constraints. To learn more review SMARTCORR\u2019s\u00ae Complete Guide To Remote Corrosion Monitoring<\/a>.<\/p>\r\n Corrosion monitoring applications can work across upstream, such as wellheads, gathering systems, and production facilities; midstream, such as transmission pipelines, compressor stations, and storage terminals; and downstream, such as refinery process units, petrochemical reactors, and heat exchangers.<\/p>\r\n Using corrosion monitoring technology at every phase of oil and gas operations is recommended. Having overlapping systems is the best corrosion protection method. In the U.S. alone, corrosion costs the oil and gas production industry an estimated $1.372 billion annually<\/a>, with corrosion responsible for 18% of significant pipeline incidents<\/a> over a 20-year period according to PHMSA data.<\/p>\r\n Different corrosive mechanisms require tailored monitoring strategies. Operators need to plan for localized corrosion testing, pipeline corrosion monitoring, and corrosion control at all stages of operations as corrosion damage can occur throughout the process.<\/p>\r\n Sour corrosion<\/a> occurs in environments containing even traces of H\u2082S, while sweet corrosion occurs in the presence of CO\u2082 only, and Microbiologically Influenced Corrosion (MIC)<\/a> is corrosion affected by microorganisms\u2019 presence or activity in biofilms. Each of these situations requires different corrosion monitoring techniques, probe types, and sampling frequencies.<\/p>\r\n SMARTCORR\u00ae has more than 20 years of experience deploying monitoring systems across these environments for clients including BP, ExxonMobil, Shell, and Halliburton, with monitoring data feeding into Corrosion Management Plans (CMP) that comply with PHMSA, NACE, and API standards.<\/p>\r\n Corrosion monitoring alone provides an incomplete picture as corrosion and erosion<\/a> are common pipe-integrity issues that occur when CO\u2082, H\u2082S, and sand exist in the gas stream at the same time. Chemical injection programs must be optimized based on real-time feedback from the erosion and corrosion process. Sand monitoring<\/a>, based on erosion measurements, has substantially reduced the cost of producing fields by controlling damage to process equipment.<\/p>\r\n Acoustic sand detection systems and erosion and corrosion probes can monitor mechanical metal loss separately from chemical corrosion, enabling operators to distinguish between corrosion-driven and erosion-driven degradation. Monitoring chemical treatments<\/a> with data loggers also obtains real-time data that can help streamline the chemical treatment process.<\/p>\r\n Pairing internal corrosion measurements with cathodic protection (CP) monitoring combines the best of internal and external monitoring. CP monitoring is the process of tracking electrical currents and voltage potentials on buried or submerged metal structures, such as pipelines or tanks, to ensure they are actively protected against corrosion. This method detects how surrounding soils, sands, and water are corroding the outside of the pipe or tank.<\/p>\r\n SMARTCORR\u00ae offer clients an integrated approach of corrosion monitoring, sand monitoring, erosion monitoring, chemical injection skids, and cathodic protection. All of these unique systems are connected through our SCEMS software as a unified corrosion control ecosystem that eliminates the coordination burden of managing multiple specialized vendors.
