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..

Customizable Corrosion Monitoring

Adapt your corrosion control strategy with coupons manufactured in a range of alloys and coatings, shaped to fit your specific applications. Our products ensure your monitoring solutions match the demands of even the harshest operating environments.

Precision and Traceability Built In

Each coupon comes pre-weighed, pre-cleaned, and carries a unique serial number, with an accompanying certificate. This guarantees both analytical precision and full traceability, supporting rigorous quality management in industrial corrosion monitoring.

Ready for Immediate, Versatile Use

Coupons are individually packed, vacuum-sealed, and shaped for easy installation-whether by hanging, flange, or custom holder. They're designed for direct process flow insertion or static racks, supporting diverse industrial setups and maintenance schedules.

FAQ's of Coated Corrosion Coupon:

Q: How are the coated corrosion coupons installed in industrial systems?

A: Installation is straightforward: the coupons can be inserted directly into process flow using flanges, racks, or custom holders, depending on your system's requirements. This flexibility ensures easy adaptation to a wide variety of pipeline and vessel configurations.

Q: What customization options are available for alloy and coating materials?

A: You can select from multiple alloys-like mild steel, 316SS, 304SS, copper, and brass-along with polymer, epoxy, or user-specified coatings, all tailored to your particular service environment and monitoring needs.

Q: When should coated corrosion coupons be inspected or replaced?

A: Inspection and replacement frequency depend on your inspection schedule and service environment. Coupons are designed for both short- and long-term monitoring, making them suitable for periodic or extended analysis based on exposure conditions.

Q: Where are these coupons typically used?

A: Coated corrosion coupons are commonly deployed in pipelines, pressure vessels, and other industrial process systems, wherever accurate monitoring of metal corrosion is essential for operational safety and asset longevity.

Q: What is the process for using corrosion coupons to determine corrosion rates?

A: Coupons are pre-cleaned, pre-weighed, installed in the system, and retrieved after a defined exposure period. Their weight loss or thickness reduction is measured, providing quantitative data for gravimetric corrosion rate calculations.

Q: How does using coated corrosion coupons benefit plant operators and service providers?

A: They provide precise, traceable measurement of corrosion rates, enabling proactive maintenance, informed material selection, and optimized asset management-all of which support reduced downtime and extended equipment life.

Q: What packaging and quality controls are provided with each coupon?

A: Each coupon comes individually vacuum-sealed to prevent contamination, with a unique serial number and a certificate for traceability. This ensures they're ready for immediate deployment and guarantees confidence in test results.
