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.

Additionally, Mett-Bio offers corrosion inhibitor bags which are best suitable corrosion resistant bags for the storage of ferrous and non-ferrous coupons..

Flexible, Chemical-Resistant Design

Constructed from highly inert elastomer, our corrosion coupon provides remarkable flexibility and outstanding resistance to a broad spectrum of chemicals. This ensures reliable performance in rigorous industrial settings and longevity throughout the corrosion monitoring period.

Precision Monitoring for Corrosion Studies

Engineered for accuracy, the coupon delivers a measuring performance with a precision of 0.5 mg and a resolution of 0.1 mg. The rectangular, smooth-as-cast surface supports comprehensive weight loss analysis, critical for evaluating material degradation in real industrial applications.

Efficient and Simple Application

Easy to mount using standard racks or holders, this single-use coupon supports straightforward, manual/static testing processes. Its ambient temperature operation, combined with a test width of 19 mm and hardness of Shore A 60-80, make it a practical tool for industrial corrosion monitoring tasks.

FAQ's of Elastomer Corrosion Coupon:

Q: How is the Elastomer Corrosion Coupon used in corrosion monitoring?

A: The coupon is mounted on a rack or holder and exposed to the environment being studied. After a set exposure period, it is removed and weighed to determine the weight loss, which indicates the level of corrosion.

Q: What benefits does the elastomer material offer compared to metallic coupons?

A: Elastomer materials are highly flexible, chemically resistant, and inert, making them ideal for environments where traditional metal coupons may degrade too quickly or fail to provide accurate readings due to chemical incompatibility.

Q: When should I replace the corrosion coupon?

A: Each coupon is designed for single use. Replace it after the completion of one exposure and weight loss measurement cycle to ensure data integrity and avoid cross-contamination.

Q: Where should the coupons be stored before use?

A: Store the coupons in a cool, dry place to prevent pre-exposure or contamination that could affect the accuracy of corrosion data collected.

Q: What is the process for measuring corrosion with this coupon?

A: Install the coupon in the monitoring environment, expose it for the specified duration, then retrieve and carefully clean the specimen before weighing to analyze weight loss due to corrosion.

Q: Is the coupon suitable for automated monitoring systems?

A: No, the coupon is intended for manual/static control and requires manual installation and retrieval. It is not compatible with automated corrosion monitoring platforms.

Q: What types of industrial applications can benefit from using this corrosion coupon?

A: Industries that require rigorous monitoring of elastomeric material degradation-such as chemical processing, water treatment, or oil and gas-can utilize these coupons to assess corrosion rates and inform material selection or maintenance schedules.
