In real life, product quality is the first thing people should pay attention to, and for some products that are used in special fields, their quality needs to be guaranteed. Take sacrificial anode products as an example, and its quality requirements are even more needless to say. So, what exactly is a high-quality sacrificial anode product? What are the effective methods for detecting the quality of sacrificial anodes? Let's listen to what the experts in the industry say.
According to experts in the region who are specialized in the research and development and production of aluminum alloy anode products, according to the difference in the protection shape of the sacrificial anode and the electrode potential, the resistivity is in the soil or freshwater environment of 20-50 ohms/meter. Depending on the potential, the choice and use of sacrificial anodes are also different. Under normal circumstances, the potential of the sacrificial anode is -1.75V CSE, and the starting voltage is 0.85v. When the salt content in the soil or water is low, the current output of the sacrificial anode will decrease, and its own corrosion will increase accordingly, so it is necessary to ensure that its current is well controlled.
When using sacrificial anodes, it is necessary not only to ensure that the electrical insulation and electrical continuity of the corrosive medium must be conductive, but also to ensure that certain conditions of use are met, so that it can be more conducive to the expected use effect. Since the sacrificial anode plays a protective role in the process of use, if the quality of the sacrificial anode is not up to standard, it will directly lead to the equipment not being able to operate normally.
The effective methods for detecting the quality of sacrificial anodes are mainly manifested in the following aspects:
1. When arranging sacrificial anodes, there should be no metal structure between the anode and the pipeline.
2. The cable joints connected to the steel pipeline should be re-treated with anti-corrosion insulation at the welding points, and hot melt adhesive and patching sheets should be used for insulation.
3. The filling material around the sacrificial anode should be dense and of uniform thickness. The filling material should be uniform, and the anode should be fully filled with water after being buried and saturated.
4. The pipeline must be insulated from the supporting piers, pipe columns, pipe bridges, fixed piers, supports, pipe clamps, casings or concrete steel bars.
5. The buried depth of the sacrificial anode connection cable shall not be less than 0.8m, and the surrounding area should be filled with plain soil or fine sand, and the upper part should be covered with cement cover plates or red bricks.
6. After installation, check the anti-corrosion layer along the entire line, and repair the damaged parts of the anti-corrosion layer. The anti-corrosion construction requirements must be the same as the original anti-corrosion layer.
Testing the quality of sacrificial anodes has always been a top priority. Only when the quality is guaranteed to meet the requirements can it better play a protective role and be more conducive to the use of equipment. Therefore, the above standards must be followed during testing.
