Our anodes are hard stamped with a heat/batch number (excludes small anodes where stamping is not possible).
This number is linked back to the spectrometer chemical analysis. This is a critical link in the quality control of anodes.
ANODE-TO-CORE RESISTANCE TESTING
The purpose of the anode-to-core resistance test is to check that there is minimal electrical resistance between the anode material and its steel core. We follow Australian standard AS2239 Annex C for testing anode-to-core resistance.
Laboratory based electrochemical testing is an accelerated corrosion test, where the rate of corrosion is measured over a short period of time. This test, along with anode potential testing, gives an indication that the anode will corrode at the desired rate when in service.
We follow the DNV-RP-B401 standard, which offers the clearest guidelines for carrying out this test.
CERTIFICATES AND DOCUMENTATION
We provide certificates for all of our inspection and testing, along with any backup documentation such as ingot and steel certificates, blasting reports, coating certificates and calibration records. For projects which require substantial inspection and testing, we compile the documentation into a Manufacturers Data Report (MDR).
