Sacrificial anode cathodic protection construction

To prevent corrosion of the pipeline, cathodic protection of sacrificial anode shall be carried out for the pipeline crossing large and medium-sized rivers and the pipeline section with strong soil corrosion at the ground bed. The main construction of sacrificial anode cathodic protection includes the installation of sacrificial anode ground bed, the installation of reference electrode, the installation of test point and the repair of pipeline. The main construction procedures are anode pit excavation, cable welding, reference electrode and test pile installation, anti-corrosion layer repair, inspection and backfilling, including test pile installation steps, cable copper core welding, test pile installation, anti-corrosion layer repair, inspection and fixation. The arrangement of the sacrificial anode has a significant distribution of the potential of the buried pipeline to the subdivision of the ground electric field.

Application of Aluminum Alloy Sacrificial Anode

Aluminum alloy sacrificial anode is suitable for ships in sea surface materials, corrosion of steel structures in sea surface, cathodic protection of pipelines corroded by industrial equipment, marine technology and port equipment, pipelines in sea mud, port logistics equipment, offshore drilling platforms and soil materials, cables and other equipment. In industrial production, the most common aluminum alloy sacrificial anode is AL-Zn-ln anodizing, which is suitable for cathodic protection of ships, ports and seaports and deep-sea equipment and buildings on the sea surface. Aluminum-zinc-indium sacrificial anode is built by fine-grained and strengthened metal materials such as high-purity aluminum and zinc. Zinc is the key to aluminum alloy sacrificial anode. In aluminum

Impressed current auxiliary anode cathodic protection

The current emitted by the cathodic protection system enters the soil through the auxiliary anode, and the current flows into the protected pipeline in the soil, and finally promotes the cathode polarization on the surface of the pipeline. In the cathodic protection of the impressed current auxiliary anode, the current will enter the negative electrode of the power supply in the pipeline, thus forming a circuit. In the whole cathodic protection system, the pipeline comes from the cathodic protection environment, because the electrons from the anode will stop corrosion, therefore, it is protected, but the auxiliary anode will corrode due to the oxidation reaction due to the loss of electrons. Cathodic protection detection, cathodic protection on the inner wall of the tank, if it is necessary to measure the potential of cathodic protection,

Cathodic protection of buried oil and gas pipelines

When the pipe crossing the railway and highway adopts casing, whether it is steel casing or concrete casing, there will be shielding effect, so that the external cathodic protection current will not reach the transmission pipe in the casing and become the blind area of cathodic protection. Once the casing enters water, the pipeline in the blind area will not be protected. For the shielding of the casing, the strip zinc anode is usually used, which is spirally wound on the pipeline and welded with the pipeline every 2m or so. Test piles should be installed at every casing, and the test wires on the casing and the pipeline can be easily tested on the ground. Jiaozuo Furuixin Nonferrous Metals Co., Ltd. produces and manages the following products: magnesium

Sacrificial anode design and installation instructions

General sacrificial anode cathodic protection project is mainly the use of magnesium alloy sacrificial anode, the main specifications of the anode is usually 22 kg/branch, in addition to the use of 14kg, 11kg, 8kg specifications, generally in the installation of a single welding or two anode in parallel for a group of installation. This is the installation method we often use in construction. If the magnesium anodes encountered in the construction need to be welded in parallel, the adjacent anode groups are well distributed on both sides of the pipeline. And the anode group is about 2.0m away from the outer wall of the pipeline and 300mm away from the outer wall of the pipeline. The small buried depth shall not be less than 1m. According to the actual situation on site, the anode position can be properly adjusted in accordance with the relevant standards and specifications. If the anode adopts a group of 4, the distance between the anode groups on the same side shall not be less than 2 meters. Jiaozuo Jiaozuo Furuixin Nonferrous Metals Co., Ltd. has a professional cathodic protection construction team.

Test method and application of pipeline cathodic protection potential check sheet

Abstract: According to the relevant standards, the evaluation of cathodic protection effect of buried steel pipeline should be based on the power failure potential index. The synchronous interruption method is usually used in the field test, but it is not suitable for the pipeline section that cannot interrupt the cathodic protection current synchronously and is disturbed by stray current. The cathodic protection potential check sheet can solve this problem, by simulating the leakage point of the pipeline anti-corrosion layer, and using the instantaneous disconnection potential of the check sheet to achieve the measurement of the approximate pipeline power-off potential. This paper introduces in detail the scope of application, design, installation, testing and analysis of pipeline cathodic protection potential inspection film, and clarifies the standardization of data records through specific implementation cases, and
