Zinc ribbon anode installation method

DECHO Metal Zinc ribbon anode meets the ASTM-B418 (Type 1/Type 2) standard and has good mechanical properties. The strip-shaped zinc anode is mainly used for the protection of the pipeline in the casing, the temporary cathodic protection of the pipeline, the protection of the storage tank and the pipeline network, and the prevention of the AC interference and lightning interference of the buried pipeline by the strong current line. Strip-shaped zinc anodes are usually used in media with a resistivity lower than 2000Ω·cm. If the steel structure to be protected has a good coating or when the soil is moist, it can be used in media with a resistivity higher than 2000Ω·cm. Main performance: good flexibility, easy installation, flexible, even current distribution, high current efficiency.
Scope of application: Mainly used in high resistivity environments, protection of pipelines in casings, temporary cathodic protection of pipelines, protection of storage tanks and pipe networks, and grounding grids that prevent strong electrical interference.

The installation method of the zinc strip sacrificial anode: After calculation, the length of the zinc strip required for the crossing is generally 4 times the length of the protected pipeline, that is, to protect 1 meter of the crossing pipeline, 4 meters of zinc strip is required. Put the zinc tape on the pipe during installation, weld one end of the zinc tape to the protected pipe (the welding point should be one meter away from the cement casing mouth, so that the casing can be blocked), wrap the zinc tape on the pipe, and finish winding Then, fix the zinc tape with a fastening tape, and weld the other end of the zinc tape to the pipeline. After the welding is completed, perform anti-corrosion treatment.
