Cathodic protection of metals in water
Cathodic protection of metals in water
Internal cable, MMO wire, HDPE (high-density polyethylene) pipe
The continuous internal cable provides a stable current for the anode
MMO wire:
1) As the anode body, it is a mixture of iridium/tantalum oxide coated on the surface of titanium wire (or according to saltwater and freshwater medium)
2) As the anode body, it is a mixture of ruthenium and iridium oxide coated on the surface of titanium wire
The nodes are made of injection molding grade, with good wear resistance, mechanical strength and corrosion resistance, which is extremely important for applications in water.

Qingdao Yinghai Corrosion and Fouling Control Technology Co., Ltd is located in the Qingdao, Shandong-the beautiful shore of Huanghai. The company is founded by professional personnel who are engaged in corrosion and protection research, development, engineering construction and project management in the research organizations and first line of engineering for a long time. The company is specialized in many fields including the comprehensive cathodic protection technology, multiple layers coating technology, heavy anti-corrosion coating technology, new technology research & development, environmental investigation, anti-corrosion design and anti-corrosion construction. Meanwhile, it manufactures and sells impressed current cathodic protection equipment and matching products in various specifications. Due to the sacrificial anode, the aluminum, zinc and magnesium alloys are applicable for the electrolysis anti-fouling products in the anti-fouling system by using the cathode copper-aluminum as well as the chlorine and copper with less circulating water. They are also suitable for the steel structure multi-layer coating products and heavy anticorrosion coatings.
