The calcium sulfate, magnesium hydroxide test electrolyte simulates the long term environment around an anode installed in the gypsum-bentonite-sodium sulfate backfill. Water Heater Anode Rod However, long term field performance properties may not be identical to property measurements obtained using this laboratory test. However, actual test comparisons are not sufficient to allow precise correlation of laboratory and field results. Magnesium Alloy Sheet Active view current version of standard.
Aluminum cathodic protection anodes for Aetm construction Service onshore solution. Work Item s – proposed revisions of this standard. Chemical compositions of High Potential Magnesium Anode: Electrochemical properties of High Potential Magnesium Anode: The largest stakeholders in the entire process is often not exactly sure what they are buying.
Sand Blast Gun 8. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine g997 applicability of regulatory limitations prior to use.
Rare Earth Oxides A method of ensuring that identical test specimens are being evaluated is to retest a test specimen. If the first installation uses unacceptable anodes, you almost certainly will have to replace the anodes at least 3 times during the life of the equipment.
Boron Carbide Nozzle Mg Mn Mg anode Shape: Note 1 — Refer to Terminology G15 for terms used in this test method. The quality of magnesium directly relates to the value of protection afforded by the Cathodic Protection system. Magnesium has the highest driving voltage of all the materials used for sacrificial anodes.
The two fundamental properties are electrode oxidation potential and ampere hours Ah obtained per t97 mass of specimen consumed. When you take a look at the below budget for installing magnesium y97, it is clear that paying a couple cents more up front for quality anodes that meet the amp hours standard of the ASTM G97 test pays for itself even before the first year of service.
However, long term field performance properties may not be identical to property measurements obtained using this laboratory test. Historical Version s – view previous versions of standard.
Professional Produce Magnesium Sacrificial Anode ASTM B / ASTM G97
aatm Total Cost per Anode: Good products, Nice services. Sacrificial water heater magnesium anode rod protects water heater from rusting Application: The calcium sulfate, magnesium hydroxide test electrolyte simulates the long term environment around an anode installed in the gypsum-bentonite-sodium sulfate backfill.
The purpose of a magnesium anode is to protect a piece of valuable equipment from corrosion. High Potential Extruded sacrificial anodes for cathodic protection G9 systems.
The degree of correlation between this test and service performance has not been fully determined.
For a more detailed analysis, please view this PDF which breaks the process down further G97 Explained. The two fundamental properties are electrode oxidation potential and ampere hours Ah obtained per unit mass of specimen consumed.

Your email address will not be published. Low Quality magnesium anode installation and premature anode failure is a concern that is not discussed enough in this industry.
I trust High Broad brand. Herein lies the problem. It is unlikely that field results of Ah per unit mass consumed would ever be greater than those measured in this test. The new diameter should be measured and the test current aztm so that the g9 current density is 0. The surface of the test specimen should be smoothed by machining before retesting. The next step is calculating the life of the equipment being protected.
Corrosion protection packaged magnesium sacrificial anode.
Magnesium Quality – G97 Test Explained
Vacuum smelting Sstm Scandium master alloy for baseball bats, lacrosse sticks, bicycle frames. Refer to Terminology G for terms used in this test method. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Of these charges, the difference in price between an anode meeting the industry requirement of 1. Aluminium Master Alloy For all they know, there could be a large rock inside the bag.
During that 20 year life span the magnesium b97 would likely have to be replaced about 2 times, once after 7 years and again after 14 these are only estimates and soil types and other surrounding conditions will cause this to vary.
For specific precautions, See Section zstm and Paragraph 8.
