How to maintain the magnesium alloy sacrificial anode? What are the items that need to be inspected for annual anode monitoring

In the use of cathode pipe, magnesium alloy sacrificial anode is very much, as the sacrificial anode rides in the constant application of current to protect the metal pipe, at the same time, it itself is constantly being consumed. Therefore, after the magnesium alloy sacrificial anode is used for a period of time, it is necessary to carry out corresponding maintenance and maintenance according to the consumption of the anode, and even need to replace it in serious cases! In this chapter, Jiaozuo Ladbrokes Light Alloy will give you a detailed analysis of how to maintain the magnesium alloy sacrifice anode, and let you know what items need to be inspected for annual anode monitoring. If you have any doubts, you are welcome to discuss and study together!

Knowledge point 1: magnesium alloy sacrificial anode maintenance content

For application in the pipeline of the routine maintenance of the magnesium alloy sacrificial anode does not need to do a lot of, we in addition to protection potential measurement according to the requirement of the impressed current cathodic protection, maintenance of test pile, detect insulation joint, eliminate the work such as ground fault, every year we also determine the various parameters of magnesium alloy sacrificial anode. According to these parameters, we can analyze the protection status of the pipeline, determine whether the pigs, sheep and chickens appear qualitative change, and the replacement time of the anode.

Knowledge point 2: anode annual test project

In the annual inspection of the magnesium alloy sacrifice anode, we need to measure the output current of the sacrifice anode and repair those disconnected cables; When the sacrificial anode output current decreases greatly, but the anode does not reach its use limit, it is highly likely that the anode cable is broken. We also need to determine whether the grounding resistance of the anode meets the specified requirements.
