We are a professional anti-corrosion materials company, integrating services, production, sales, and comprehensive anti-corrosion design, construction, installation, and technical services. The construction requirements for magnesium alloy sacrificial anodes first involve the burial requirements: prepare the backfill material, mix it in proportion and stir evenly, then fill it into a cotton bag measuring 30 cm in diameter and one meter in length. Clean the anode surface as required, then insert it into the center of the prepared backfill material and compact it. The outer part of the backfill material should be tightly bound and laid flat or vertically, buried at the same depth, 2 to 3 meters away from the protected pipeline. Finally, use prepared fine soil mixed with salt to fill and level the anode pit. When connecting cables to other devices, soldering must be used, except for connection wires inside the junction box. Before soldering, remove the anti-corrosion insulation layer and clean the surface; after soldering, apply anti-corrosion insulation treatment to the soldered points; the burial depth of the cables should be the same as that of the pipeline. Cables must have a sufficient reserve length of about 0.8 meters, which should not include the protective pipe, to facilitate future maintenance by lifting the junction box above ground for testing; the burial of the junction box must be compacted and waterproofed. Cable colors should be distinguishable, and permanent markers should be placed around the burial location of the anode.

The sacrificial anode kit assembly is designed by our company to meet the high-paced and efficient construction requirements of engineering projects. Based on the traditional single sacrificial anode, it is supplemented with matching accessories for assembly, making construction more convenient, time-saving, and labor-saving for customers.

Kit configuration: One sacrificial anode of any specification, one cable, several kilograms of backfill material, one cotton bag, and one plastic woven bag. The composition of the backfill material is: (1) Gypsum powder: 75%, (2) Bentonite: 20%, (3) Anhydrous sodium sulfate: 5%. The sacrificial anode kit assembly is a new concept anode product developed by our company to adapt to the high-paced and efficient construction requirements of engineering projects. It builds on the traditional single sacrificial anode and is supplemented with matching accessories, making construction more convenient and time-saving for customers, better meeting their needs. Kit configuration: One sacrificial anode of any model. One cable: Welded to the sacrificial anode according to the length and specifications required by the customer, and sealed with epoxy resin and dibutyl phthalate in proportion using glass fiber cloth or polyethylene heat-shrink tubing. One package of specialized backfill material. One set of thermite welding agent. One anode cloth bag. Product specifications: Include D-type, S-type, C-type, various special shapes, and extruded embedded anodes. Magnesium alloy sacrificial anode - pre-packaged anode: (including high-potential and low-potential) is the final product of cast anodes and can be directly applied in engineering construction.

Magnesium anodes have high driving voltage, low current efficiency, and high cost. Depending on their shape and electrode potential (open-circuit potential), magnesium anodes can be used in soil or freshwater environments with resistivity ranging from 15 ohm-meters to 150 ohm-meters. They are generally not used in environments with soil resistivity less than 10 ohm-meters. The potential of high-potential magnesium anodes is -1.75V CSE, with a driving voltage of 0.85V; the potential of low-potential magnesium anodes is -1.55V CSE, with a driving voltage of 0.7V. The operating temperature can reach 100°C. When the remaining amount of the sacrificial anode is 15% of its initial weight, the anode is considered失效 (failed), so the utilization rate of the anode is generally taken as 85%. Building on the traditional anode, supplemented with matching accessories, this new concept anode product makes construction more convenient and time-saving for customers, better meeting their needs.
