When you take a look at the below budget for installing magnesium anodes, 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.
Link to Active This link will always route to the current Active version of the standard.
Professional Produce Magnesium Sacrificial Anode ASTM B843 / ASTM G97
Below is a sample budget for a 50 anode installation, taking 3 men one day to complete 24 man hours. 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. Total Cost per Anode: The degree of correlation between this test and service performance has not been fully determined.
The values given in parentheses after SI units are provided for information only and aastm not considered standard.
The two fundamental properties are electrode oxidation potential and ampere hours Ah obtained per unit mass of specimen consumed. Electrochemical properties of High Potential Magnesium Anode: The largest stakeholders in the entire process is often not exactly sure what they are buying. For all they know, there could be a large rock inside the bag. Now this may be a very rudimentary calculation, but the basic principle will always hold true.
Magnesium Quality – G97 Test Explained – American Carbon Company
A method of ensuring that identical test specimens are being evaluated is to retest a test specimen. High Potential Extruded sacrificial anodes for cathodic protection CP systems. Low Quality magnesium anode installation and premature anode failure is a concern that is not discussed enough in this industry. Mg Mn Mg anode Shape: We worked well as best partners.
g997 Note 1 y97 Refer to Terminology G15 for terms used in this test method. This value was chosen for illustrative purposes only, and in no way claims any one manufacturer consistently manufactures anodes of this quality. If you have skype or whatsapp, pls tell me, we can chat more smoothly. I puchase cathodic protection anodes from High Broad from year Aluminium Master Alloy People often say aatm us, magnesium is magnesium — what is the difference.
Work Item s – proposed revisions of this standard. The next step is calculating the life of the equipment being protected. Chemical compositions of High Potential Magnesium Anode: Of these charges, the difference in price between an anode meeting the industry requirement of 1.
The new diameter should be measured and the test current adjusted so that the retest current density is 0. Magnesium Master Alloy Good products, Nice astk. The calcium sulfate, magnesium hydroxide test electrolyte simulates the long term environment around an anode installed in the gypsum-bentonite-sodium sulfate backfill. Rare Earth Oxides High Potential Magnesium anode is used as a sacrificial anode in cathodic protection.
Professional Produce Magnesium Sacrificial Anode ASTM B / ASTM G97
For specific precautions, See Section 7 and Paragraph 8. Storage Tank Base, pipelines Standard: I trust High Broad brand. The calcium sulfate, magnesium hydroxide test electrolyte simulates the long term environment around an anode installed in the gypsum-bentonite-sodium sulfate backfill. Referenced Documents purchase separately The documents listed below are g977 within the subject standard but are not provided as part of the standard.
Cathodic protection magnesium sacrificial anode for underground oil pipelines.
Sacrificial water heater magnesium anode rod protects water heater from rusting Application: Aluminum Heater Ashm Anode rod provide maximum performance in seawater.
The surface of the test specimen should be smoothed by machining before retesting. For specific precautions, See Section 8 and Paragraph 9. Making the World a cleaner, more efficient place since It is unlikely that field results of Ah per unit mass consumed would ever be greater than those measured in this test.
