At present, there are many methods for determining the corrosion rate, such as gravimetric method, volume method, polarization curve method (polarization resistance method) and so on. Gravimetric method is a classic method, which is suitable for laboratory and field coupons. It is one of the most reliable methods for determining the corrosion rate of metals. It can be used to detect the corrosion resistance of materials, select corrosive agents, and check the anti-corrosion effect when changing process conditions.

The EMT Access Fitting Assembly is a device mounted on the pipeline. You can equip it with corrosion coupons or injection quill to monitor or maintain the pipe.
