Mett-Bio Metallurgical Testing and Analysis is an independent R&D division with ISO 17025:2017 (NABL) accreditation, located in Ahmedabad, India. is involved in corrosion testing and failure analysis since 2013.

We are glad to announce Corrosion Test Coupons, an inexpensive online monitoring tool that will allow you to properly monitor corrosion within your systems. The mile per year corrosion rate of an exposed coupon can be used to easily determine the materials life.

Mett-Bio can help you manufacture coupons in any shape, size, and material (ferrous, non-ferrous, and elastomeric). Depending on the requirements, a suitable marking can also be stencilled on the coupons. Typical coupon shapes include flat strip coupons, disc coupons, and cylinder coupons. Mett-Bio provides a variety of coupon holders and can also develop and manufacture custom holders to meet specific requirements..

Reliable Corrosion Monitoring

Track corrosion processes effectively with our cylindrical corrosion coupons. Designed to deliver high sensitivity and robust performance, these coupons are an industry standard for assessing the longevity and integrity of metal structures exposed to various environments. Their precise geometry and material options ensure reliable measurement and compatibility with your specific industrial application.

Customizable to Your Needs

Select from standard or tailored specifications for materials, dimensions, and finishes. Each coupon can be engraved for clear identification, and packaging ensures each piece arrives in perfect condition. The design allows for flexible mounting, supporting both threaded and plain end installations, making them adaptable to different testing environments.

FAQ's of Cylindrical Corrosion Coupon:

Q: How do I use the cylindrical corrosion coupon in industrial testing?

A: To use the coupon, manually place it at a designated location within your system-such as a pipeline or vessel-using the appropriate mounting type. After the exposure period ends, the coupon is removed and visually inspected or measured to quantify metal loss due to corrosion.

Q: What materials are available for these corrosion coupons?

A: The coupons can be manufactured from mild steel, stainless steel, copper, brass, or other specified metals to suit your application's requirements. Material selection affects corrosion response and ensures accurate monitoring for different environments.

Q: When should I replace or remove the corrosion coupon during testing?

A: The duration depends on your specific test protocol and the environment's aggressiveness. Typically, coupons remain exposed for periods ranging from a few days to several months, according to inspection schedules or until sufficient data is gathered.

Q: Where should these coupons be installed for effective corrosion monitoring?

A: Install the coupon at critical monitoring points within systems prone to corrosion, such as pipelines, vessels, or closed loops. Placement should mirror typical exposure conditions to collect representative data.

Q: What is the process for evaluating corrosion using these coupons?

A: After exposure, the coupon is extracted, cleaned according to test standards, and assessed for weight loss or surface changes. The results reveal the corrosion rate, which can be calculated with high accuracy and sensitivity.

Q: What are the main benefits of using these corrosion coupons?

A: They provide accurate, cost-effective monitoring of corrosion rates, allowing proactive maintenance and asset protection. The coupons are easy to install, highly sensitive, compatible with multiple test conditions, and customizable for unique requirements.
