Axiom’s Materials utilise extensive knowledge, experience and existing data, coupled with a range of corrosion testing techniques, to understand what is happening to your plant and equipment.
Some clients complain that they don’t understand why their assets are disappearing before their eyes, or that the materials of their plants are reverting back to their native state. If you have a complaint similar to these, then perhaps you should talk to the Axiom’s materials and corrosion engineers.
Axiom’s Materials Section utilise extensive knowledge, experience and existing data, coupled with at least three types of corrosion testing, to understand what is happening to your plant and equipment.
Backed up by a well-equipped metallurgical laboratory and Scanning Electron Microscope (SEM) suite, these facilities allow Axiom to understand exactly what is happening in your kit.
This allows us to then advise you how to minimise the corrosion taking place, be that by process changes, material changes or operational changes.
1. Cheap and Cheerful - exposure testing at ambient pressure and moderate temperatures, ambient to 90°C, can be run for up to 28 days to get actual corrosion rates from materials in your process fluids.
2. Under Pressure - autoclave corrosion testing, as above, but with the capability of going to 300°C and 1500 psig. A more realistic and possibly onerous test technique for many processes.
3. The Quickie - electrochemical potentiodynamic cyclic polarisation testing - a rapid technique for looking at the risk of various types of corrosion. No actual corrosion rates, but an indication of risk. Only suitable for electrically conductive solutions.
But don’t wait for things to go wrong. Ask the question early, “What will happen if...”, or “What if we change the temperature of…” and see what sort of an answer you get. Sometimes it will be positive and almost casual, but other times it may just save you plant from an experience, the likes of which you would rather never have heard about.
