February 18, 2023Uncategorizedmethods of corrosion measurementsadmin

Electrochemical impedance spectroscopy

Electrochemical impedance spectroscopy (EIS) is a widely used technique for monitoring corrosion rates in the oil and gas industry. EIS involves measuring the electrical response of a metal coupon to a small sinusoidal electrical potential, over a range of frequencies. The resulting impedance spectrum can be analyzed to determine the corrosion rate and the corrosion mechanism.

The principle behind this method is that as a metal corrodes, its electrical properties change, which affects the impedance response of the metal. The impedance spectrum is then analyzed using mathematical models to determine the corrosion rate and mechanism.

EIS is a powerful technique for monitoring corrosion rates, as it can provide detailed information on the corrosion mechanism and the effects of environmental factors such as temperature, pressure, and composition. This method can detect both uniform and localized corrosion, including pitting and crevice corrosion, which may not be detected by other techniques.

However, EIS is a complex and time-consuming technique that requires specialized equipment and expertise. The interpretation of the data requires mathematical modeling, which can be challenging and may require significant experience to accurately interpret the results.

Despite these limitations, EIS is a valuable technique for monitoring corrosion rates in the oil and gas industry. It can be used to optimize corrosion control strategies, to evaluate the performance of corrosion inhibitors and other protective coatings, and to provide insights into the mechanisms of corrosion. EIS is often used in combination with other corrosion monitoring techniques, such as weight loss measurement and polarization resistance measurement, to provide a more comprehensive understanding of the corrosion process.

Hydrogen permeation measurement

Hydrogen permeation measurement is a specialized technique for monitoring hydrogen-induced cracking in the oil and gas industry. This method involves exposing a metal coupon to a corrosive environment containing hydrogen, and measuring the amount of hydrogen that diffuses into the metal. The amount of hydrogen uptake is proportional to the risk of hydrogen-induced cracking, and can be used to evaluate the performance of materials and coatings in environments containing hydrogen.

The principle behind this method is that as a metal is exposed to a hydrogen-containing environment, some of the hydrogen will diffuse into the metal, causing hydrogen embrittlement and increasing the risk of cracking. The amount of hydrogen that diffuses into the metal is dependent on factors such as the material properties, the environmental conditions, and the presence of protective coatings.

Hydrogen permeation measurement is a complex and specialized technique that requires specialized equipment and expertise. The equipment used for hydrogen permeation measurement is typically expensive and requires regular calibration and maintenance. Additionally, the test conditions and parameters must be carefully controlled to ensure accurate and reproducible results.

Despite these limitations, hydrogen permeation measurement is a valuable technique for evaluating the risk of hydrogen-induced cracking in the oil and gas industry. This method can be used to evaluate the performance of materials and coatings under realistic conditions, and to optimize corrosion control strategies to minimize the risk of hydrogen-induced cracking. Hydrogen permeation measurement is often used in combination with other corrosion monitoring techniques, such as weight loss measurement and electrochemical techniques, to provide a more comprehensive understanding of the corrosion process.

Ultrasonic thickness measurement

Ultrasonic thickness measurement is a widely used technique for monitoring corrosion rates in the oil and gas industry. This method involves using ultrasonic waves to measure the thickness of a metal coupon or structure, and then comparing the thickness measurements over time to evaluate the corrosion rate.

The principle behind this method is that as a metal corrodes, its thickness decreases, which can be detected using ultrasonic waves. The equipment used for ultrasonic thickness measurement typically consists of a handheld probe, which emits and receives ultrasonic waves, and a digital display or data logger, which displays the thickness measurements.

Ultrasonic thickness measurement is a non-destructive and non-intrusive technique, which makes it a convenient and safe method for monitoring corrosion rates. This method is also less affected by environmental factors, such as temperature and composition, compared to other corrosion monitoring techniques, such as weight loss measurement.

However, ultrasonic thickness measurement has its limitations in terms of the accuracy of the corrosion rate calculation. This method may not detect localized corrosion, such as pitting, and the thickness measurements may be affected by the geometry and surface finish of the metal coupon or structure. Additionally, this method cannot provide insights into the corrosion mechanism or the effects of environmental factors on the corrosion process.

Despite these limitations, ultrasonic thickness measurement is a valuable technique for monitoring corrosion rates in the oil and gas industry. This method can be used to provide real-time monitoring of the thickness of pipelines, tanks, and other equipment, to identify areas of high corrosion rates, and to optimize corrosion control strategies. Ultrasonic thickness measurement is often used in combination with other corrosion monitoring techniques, such as weight loss measurement and electrochemical techniques, to provide a more comprehensive understanding of the corrosion process.

Visual inspection methods

Visual inspection methods are the oldest and most common techniques for monitoring corrosion rates in the oil and gas industry. This method involves the direct observation of the metal surface, either through direct visual inspection or through the use of visual aids such as magnifying lenses or video cameras.

The principle behind this method is that as a metal corrodes, visible changes occur on the surface of the metal, such as discoloration, pitting, and scaling. These changes can be detected through visual inspection and can be used to evaluate the corrosion rate and the effectiveness of corrosion control strategies.

Visual inspection methods are inexpensive and easy to perform, making them a convenient and accessible technique for monitoring corrosion rates. This method is also less affected by environmental factors, such as temperature and composition, compared to other corrosion monitoring techniques.

However, visual inspection methods have their limitations in terms of the accuracy of the corrosion rate calculation. This method may not detect early stages of corrosion, where the changes are not visible to the naked eye, and may not be able to detect localized corrosion such as pitting, under coatings or within complex geometries. Additionally, visual inspection methods cannot provide insights into the corrosion mechanism or the effects of environmental factors on the corrosion process.

Despite these limitations, visual inspection methods are a valuable technique for monitoring corrosion rates in the oil and gas industry. This method can be used to identify areas of high corrosion rates, to evaluate the effectiveness of corrosion control strategies, and to guide more detailed and precise monitoring techniques. Visual inspection methods are often used in combination with other corrosion monitoring techniques, such as weight loss measurement, electrochemical techniques, and ultrasonic thickness measurement, to provide a more comprehensive understanding of the corrosion process.

Visual inspection: The first step in corrosion coupon interpretation is to visually inspect the coupon for signs of corrosion, such as pitting, scaling, or discoloration.
Weight loss analysis: Corrosion coupons are typically weighed before and after exposure to the environment to determine the weight loss due to corrosion. The weight loss is used to calculate the corrosion rate.
Corrosion rate calculation: The corrosion rate can be calculated using the weight loss data, the surface area of the coupon, and the exposure time. The corrosion rate can be expressed as mils per year (MPY), or millimeters per year (mm/year).
Corrosion type identification: Based on the visual inspection and weight loss analysis, the type of corrosion can be identified. The three main types of corrosion are general corrosion, localized corrosion, and stress corrosion cracking.
Corrosion mechanism identification: The mechanism of corrosion can also be identified based on the visual inspection and weight loss data. For example, pitting corrosion occurs due to the presence of a localized electrochemical cell, while crevice corrosion occurs in crevices where stagnant solutions can accumulate.
Interpretation of results: The results obtained from the corrosion coupon analysis can be used to develop effective corrosion control strategies, such as selecting appropriate materials, coatings, and inhibitors.

Corrosion type identification

Corrosion type identification is a critical step in the corrosion coupon interpretation process. It involves identifying the type of corrosion that has occurred on the surface of the coupon.

There are several types of corrosion that can occur, including uniform corrosion, pitting corrosion, crevice corrosion, galvanic corrosion, intergranular corrosion, and stress corrosion cracking. Each type of corrosion has a unique appearance and occurs due to different factors, such as the presence of specific chemicals, exposure to specific environmental conditions, or the nature of the materials involved.

The visual appearance of the corrosion on the coupon is often the first clue to identifying the type of corrosion. For example, uniform corrosion appears as a general, even loss of material across the surface of the coupon, while pitting corrosion appears as small, localized holes in the surface of the coupon.

In addition to visual inspection, other techniques may be used to identify the type of corrosion, such as microscopy or chemical analysis. Microscopy can provide a detailed view of the structure of the material and can be used to identify the presence of specific types of corrosion. Chemical analysis can be used to identify the presence of specific chemicals that contribute to corrosion.

Overall, corrosion type identification is a critical step in the corrosion coupon interpretation process, as it provides valuable information about the factors that contribute to corrosion and the most effective corrosion control strategies. This information can be used to develop effective corrosion control strategies and to prevent further damage to equipment and materials.

To calculate the corrosion rate, the weight loss data obtained from the corrosion coupon is used, along with the surface area of the coupon and the exposure time. The formula for calculating the corrosion rate is:

Corrosion rate = (Weight loss in grams / (Surface area in square inches x Exposure time in hours)) x 87,600

In this formula, 87,600 is a conversion factor used to convert the corrosion rate from inches per hour to mils per year.

Once the corrosion rate is calculated, it can be used to compare the corrosion resistance of different materials, to monitor changes in corrosion rates over time, and to assess the effectiveness of corrosion control strategies.

Overall, the corrosion rate calculation is an essential step in the corrosion coupon interpretation process, as it provides a quantitative measure of the amount of material loss due to corrosion. This information can be used to develop effective corrosion control strategies and to prevent further damage to equipment and materials.

A corrosion coupon and probe are devices used to monitor and measure corrosion in pipelines, storage tanks, and other metal structures. They are used to determine the rate and extent of corrosion, which can help prevent costly damage and extend the lifespan of the equipment.

A corrosion coupon is a small piece of metal that is placed in the environment being monitored. Over time, the coupon will corrode at a rate similar to the metal surrounding it. The amount of corrosion can be measured by weighing the coupon before and after the exposure period, or by using an electrochemical method to measure the corrosion rate.

A corrosion probe, on the other hand, is an electrochemical sensor that is inserted into the metal structure being monitored. The probe measures the electrical resistance of the metal, which changes as the metal corrodes. There are two main types of corrosion probes: linear polarization resistance (LPR) probes and impressed current probes. LPR probes measure the corrosion rate of a metal, while impressed current probes use a small current to slow down the corrosion rate.

By using a combination of corrosion coupons and probes, engineers and maintenance professionals can monitor the health of their equipment and take action to prevent further corrosion, extending the lifespan of the equipment and reducing the risk of costly failures.

Open Circuit Potential (OCP) Probe: This type of probe measures the electrical potential of the metal surface in the absence of any current flow. The probe consists of a single electrode that is placed in contact with the metal surface. The electrical potential is then measured and used to determine the corrosion rate.

Each type of corrosion probe has its own strengths and weaknesses, and the choice of probe will depend on the specific requirements of the application, such as the type of metal being monitored, the environment in which the metal is located, and the desired level of accuracy and detail of the corrosion data.

Linear Polarization Resistance (LPR) Probe

Linear Polarization Resistance (LPR) probe is a type of corrosion probe that is commonly used to monitor corrosion in pipelines, storage tanks, and other metal structures. The probe measures the electrical resistance of the metal surface and is used to determine the corrosion rate.

The LPR probe consists of two electrodes that are placed in contact with the metal surface and a voltage is applied between the electrodes. The electrical resistance between the electrodes is then measured, and the corrosion rate can be calculated from this value. The LPR probe works on the principle that the corrosion process increases the electrical resistance of the metal surface, and the magnitude of this increase is proportional to the corrosion rate.

One of the advantages of the LPR probe is its simplicity and ease of use. The probe requires only a simple voltage source and a meter to measure the electrical resistance, making it a cost-effective option for corrosion monitoring. The LPR probe is also relatively insensitive to environmental factors such as temperature and humidity, making it a reliable option for monitoring corrosion in a variety of conditions.

However, the LPR probe is limited in its accuracy and detail of the corrosion data. The probe only provides a general indication of the corrosion rate, and it is not possible to determine the specific type of corrosion or the location of the corrosion using this probe. Additionally, the probe is not suitable for monitoring very low corrosion rates or for detecting localized corrosion, such as pitting corrosion.

Overall, the LPR probe is a useful tool for monitoring general corrosion in metal structures, and is an excellent starting point for corrosion monitoring programs. However, for more detailed or specialized corrosion monitoring, other types of probes, such as Electrochemical Impedance Spectroscopy (EIS) probes, may be more appropriate.

Electrochemical Noise (EN) Probe

The Electrochemical Noise (EN) probe is a type of corrosion probe that is used to monitor the electrical noise generated by corrosion processes at the metal surface. The probe measures the electrical noise and is used to determine the corrosion rate.

The EN probe consists of two electrodes that are placed in contact with the metal surface and an electrical potential is applied between the electrodes. The electrical noise generated by the corrosion processes is then measured and analyzed to determine the corrosion rate. The EN probe works on the principle that the corrosion process generates electrical noise that is proportional to the corrosion rate.

One of the advantages of the EN probe is its ability to detect and quantify localized corrosion, such as pitting corrosion. The electrical noise generated by localized corrosion is different from the noise generated by general corrosion, and the EN probe is able to distinguish between these two types of corrosion. This makes the EN probe a valuable tool for monitoring corrosion in structures that are susceptible to localized corrosion.

Another advantage of the EN probe is its sensitivity to the type of corrosion. Different types of corrosion, such as general corrosion and pitting corrosion, generate different electrical noise, and the EN probe is able to distinguish between these different types of corrosion. This allows the probe to provide detailed information about the type and location of the corrosion, which can be valuable in identifying the causes of corrosion and developing strategies to mitigate it.

However, the EN probe is limited in its accuracy and precision compared to other types of corrosion probes. The electrical noise generated by corrosion processes can be affected by many environmental factors, such as temperature and humidity, which can make it difficult to accurately quantify the corrosion rate using the EN probe. Additionally, the EN probe can be more complex to use and interpret than other types of corrosion probes, requiring specialized equipment and expertise.

Overall, the EN probe is a valuable tool for monitoring localized corrosion in metal structures, and is especially useful for structures that are susceptible to pitting corrosion. The probe provides valuable information about the type and location of corrosion, which can be used to identify the causes of corrosion and develop strategies to mitigate it.

Planning and Preparation

Planning and preparation is a critical step in the installation of corrosion coupons and probes. During this stage, the location of the coupon and probe, as well as the equipment and materials needed for the installation, are determined.

To determine the location of the coupon and probe, engineers consider the environment in which the metal structure is located, the flow patterns of liquids or gases within the structure, and the potential for localized corrosion. This information helps to identify the areas of the structure that are most susceptible to corrosion, and where the coupon and probe should be placed to provide the most accurate readings.

In terms of equipment and materials, engineers will need to consider the type of coupon or probe to be used, as well as any tools or supplies needed to attach the coupon or insert the probe into the metal structure. This might include drill bits, adhesives, and protective coatings.

Proper planning and preparation can ensure that the installation of the corrosion coupon and probe is completed quickly and accurately, with minimal disruption to the metal structure and its surrounding environment. This sets the foundation for a successful corrosion monitoring program that provides valuable data to help prevent corrosion and extend the lifespan of the equipment.

Installation of the corrosion coupon

The installation of the corrosion coupon is an important step in the process of monitoring corrosion in pipelines, storage tanks, and other metal structures. The goal of the installation is to attach the coupon to the metal surface in a way that accurately represents the rate and extent of corrosion in the environment.

The first step in the installation process is to prepare the surface where the coupon will be attached. This may involve cleaning the surface of any dirt, grease, or other contaminants that could interfere with the coupon’s ability to corrode. In some cases, a protective coating may be applied to the coupon to prevent it from corroding too quickly.

Next, the coupon is attached to the metal surface using an adhesive or other method, such as clamping or welding. The coupon should be placed in a location that represents the general corrosion environment within the metal structure. For example, in a pipeline, the coupon might be placed near a bend or in a section of the pipe that is prone to localized corrosion.

Once the coupon has been attached, the initial reading is recorded. This reading serves as a baseline for future measurements and allows engineers to determine the rate at which the coupon is corroding over time. Periodic measurements of the coupon weight or corrosion rate will be taken to monitor the corrosion environment within the metal structure.

Proper installation of the corrosion coupon is critical to obtaining accurate and meaningful data on the corrosion rate and extent within a metal structure. By following best practices and using the right tools and materials, engineers can ensure that the coupon provides valuable information that can be used to prevent corrosion and extend the lifespan of the equipment.

Installation of the corrosion probe

The installation of a corrosion probe is a critical step in the process of monitoring corrosion in pipelines, storage tanks, and other metal structures. The goal of the installation is to insert the probe into the metal surface in a way that accurately represents the rate and extent of corrosion in the environment.

The first step in the installation process is to prepare the surface where the probe will be inserted. This may involve cleaning the surface of any dirt, grease, or other contaminants that could interfere with the probe’s ability to accurately measure the corrosion rate. In some cases, a protective coating may be applied to the probe to prevent it from corroding too quickly.

Next, the probe is inserted into the metal surface using a drill or other method. The probe should be placed in a location that represents the general corrosion environment within the metal structure. For example, in a pipeline, the probe might be placed near a bend or in a section of the pipe that is prone to localized corrosion.

Once the probe has been inserted, the electrical resistance of the metal surrounding the probe is measured. This measurement serves as a baseline for future readings and allows engineers to determine the rate at which the metal is corroding over time. Periodic measurements of the electrical resistance will be taken to monitor the corrosion environment within the metal structure.

Proper installation of the corrosion probe is critical to obtaining accurate and meaningful data on the corrosion rate and extent within a metal structure. By following best practices and using the right tools and materials, engineers can ensure that the probe provides valuable information that can be used to prevent corrosion and extend the lifespan of the equipment.

Post-installation procedures

Post-installation procedures are an important step in the process of monitoring corrosion in pipelines, storage tanks, and other metal structures using corrosion coupons and probes. These procedures are designed to ensure that the data collected from the coupons and probes is accurate, consistent, and meaningful, and to prevent contamination or damage to the coupons and probes.

One of the key post-installation procedures is to regularly monitor the coupons and probes and record the readings. This might involve periodically measuring the weight of the corrosion coupon, the electrical resistance of the corrosion probe, or both. The data collected during these monitoring sessions should be recorded in a logbook or other document for later analysis.

Another important post-installation procedure is to periodically inspect the coupons and probes to ensure that they remain securely attached to the metal surface and that they are free from damage or contamination. In some cases, it may be necessary to clean the coupons and probes or to reapply a protective coating to maintain their accuracy.

It is also important to maintain accurate records of the data collected from the coupons and probes, as well as any repairs or maintenance performed on the coupons and probes. This information can be used to identify trends in the corrosion rate and to make informed decisions about how to prevent corrosion and extend the lifespan of the equipment.

By following best practices for post-installation procedures, engineers can ensure that the data collected from the corrosion coupons and probes is accurate, consistent, and meaningful. This information can be used to make informed decisions about how to prevent corrosion and extend the lifespan of the equipment, ultimately helping to reduce costs and improve safety.
