Ferrite testing can be conducted on welding and piping products with our portable hand held battery operated Fischer Feritscope MP30E-S ferrite testers. Our clients require us to undertake testing of substantial quantities of sub-sea wellhead Duplex and Super Duplex welded piping spools and their associated components.
Heat treatment to these products may result in ferrite levels dropping below certain percentage levels, this can subsequently show that incorrect heat treatment has been applied to the product or the presence of third phases in the material which can be detrimental to the in-service life of Duplex and Super Duplex.
We test using methods that ensure obtained ferrite readings are correct and are truly relative to the samples under test.
We can also test certain austenitic weld metals for deposited ferrite content.
