　　product type:Pre-packed high silicon cast iron anodes

　　Product performance:Low consumption rate, low grounding resistance, stable output current and voltage, convenient construction.Therefore, the anode body is widely used in cathodic protection construction.

　　Scope of application:Auxiliary anode for impressed current cathodic protection systems.

　　Detail Introduction:

　　The pre-packed high silicon cast iron anode body is mainly composed of anode, coke packing, guide pipe and steel casing, etc.The anode is made of high silicon cast iron, which is first fixed in the center of the steel sleeve with a support, and then filled with coke packing around the guide pipe.According to different construction needs, high silicon cast iron anode can be used the following models: φ 50*1500 or 75*1500, this product greatly reduces the working time of the construction site, the original construction site operation will be completed in the factory, improve the work efficiency and ensure the quality of the project.

　　Especially for the areas with high soil resistivity, such as Xinjiang and other northwest regions are located in the inland of China, with scarce precipitation, surface drought and serious water shortage;When the soil environment is sand, gobi, etc., the soil resistivity is extremely high, which leads to the failure of the cathodic protection system to operate normally and accelerates the corrosion rate of the pipeline.This anode, along with a pre-packaged noble metal oxide anode, has been specifically developed for this type of environment.The anode is deep into the humid soil tens of meters underground, which can effectively reduce the grounding resistance of the anode, greatly improve the coverage of the cathodic protection system, and extend the life of underground structures such as pipelines.Save the operation and maintenance cost of cathodic protection system.It is an ideal cathodic protection material with high soil resistivity.
