Mett-Bio s an independent testing and analysis division with ISO 17025:2017 accreditation located at Ahmedabad is involved with Corrosion Testing and Failure Analysis since 2013. We are pleased to introduce the Corrosion Test Coupons an inexpensive means of on-line monitoring that will allow you to monitor the corrosion within your systems effectively. Materials life assessment can be easily assessed based on the mile per year corrosion rate of an exposed coupon.

Mett-Bio can help you make coupon in any shape, size and material (viz. ferrous, non-ferrous and elastomeric) you need. Suitable marking can be stencilled on the coupons as-well based on the requirement. Typical Coupons shape manufactured are: Flat Strip Type, Disc Coupons and Cylindrical Coupons. Mett-Bio offers a variety of coupon holders and additionally can design and manufacture custom holders as per requirements..

Precision Engineering for Accurate Corrosion Analysis

Each Tensile Corrosion Coupon is produced with tight thickness tolerance and standardized dimensions, ensuring reliable results in every test. Available in various materials, these coupons cater to specific industry needs, accommodating different shapes and finishes as required by testing standards or custom applications.

Comprehensive Corrosion Monitoring Applications

Primarily used to assess corrosion rates in piping systems, tanks, and vessels, the coupon's design allows for both weight loss and tensile strength evaluation. This versatility helps organizations proactively monitor and manage potential material degradation in a broad range of environments.

Ready-To-Use and Easy Handling

Delivered pre-cleaned and vacuum-sealed in a pouch with an identification label, each coupon is field-ready, reducing sample preparation time and contamination risk. Mounting is straightforward, with a fixed holder or slot ensuring secure placement during testing.

FAQ's of Tensile Corrosion Coupon:

Q: How do I use the Tensile Corrosion Coupon for corrosion monitoring?

A: To use the coupon, simply remove it from its vacuum-sealed pouch, ensure the serial and heat numbers are recorded, and mount it onto your testing holder or slot. Expose it to the desired environment and, after the stipulated test period, analyze weight loss or tensile loss to evaluate corrosion rates.

Q: What materials are available for the Tensile Corrosion Coupon and why is this important?

A: Coupons are offered in carbon steel, stainless steel, and a range of other alloys. Selecting the right material is crucial, as it should match or mimic the parent material of the system under study, providing accurate and representative corrosion data.

Q: When should I replace or use a new coupon?

A: It's advisable to use a new coupon for each test cycle or after significant exposure to ensure precision in measurements. Coupons have a shelf life of up to two years when unexposed and stored in their vacuum-sealed packaging.

Q: Where can these coupons be employed for corrosion studies?

A: These coupons are designed for installation in various environments, including piping networks, storage tanks, and vessel interiors. Their standard size fits industry-standard slots, providing flexibility across different monitoring setups.

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

A: After mounting, the coupon is exposed to the target environment for a predefined duration. Periodically or at the end of exposure, you remove, clean, and weigh or test the specimen for tensile strength loss, following ASTM G1, NACE TM0169/G31, or custom procedures as required.

Q: How does using the tensile corrosion coupon benefit my corrosion monitoring program?

A: Using these coupons provides highly accurate, reliable, and standardized data on corrosion and material loss, enabling informed asset management and preventive maintenance decisions. Their durability and traceable identification further enhance testing efficiency and result credibility.
