The main purpose of sacrificial anode pair and quality control is to simplify the analysis and control of the chemical composition of the alloy, as well as the joint degree material between the support and anode, the quality support of anticorrosive coating and the quality and size of anode.
Since the free flow test will last for a long time, we need to conduct another short-term constant current test in the control process. In addition, some technical specifications describe the special test conditions related to the actual situation. However, such test results can only represent the values that can be compared at present, and can not be used as valid data in the actual situation. We need to protect the anode material for a long time. Some special alloys are required to be strictly controlled in production. This special anode material usually requires a test certificate.
Shandong Linyi Bosi conductive materials Co., Ltd. is a high-tech enterprise specializing in the production of MMO flexible anode, conductive polymer flexible anode and titanium coated anode, mainly providing cathodic protection technology, engineering design, installation and technical services.
The application of sacrificial anode cathodic protection usually does not need a large technical cost. After the installation of cathodic protection system is completed, as long as the protection current or potential is checked occasionally, the later operation hardly needs maintenance. Because of the low driving voltage, it will not interfere with the nearby structure, so the cathodic protection system of sacrificial anode does not need alternating current. Because the voltage is relatively low, there is no safety problem. Therefore, the sacrificial anode system can be installed in areas with explosion risk.
For corrosion protection in soil, the anode can be placed together with the protected structure and buried in the same pit without excavation. The anode is connected with the local harmful structure to overcome the interference.
However, due to the low driving voltage, the application of sacrificial anode in soil and medium with poor conductivity is limited. If it is necessary to increase the current output, but only increase the external voltage is feasible. In special cases, if the installed sacrificial anode has excessive calendering, such as banding or reaction products can increase its supplementary function, it should be used.
