Product Description

Prepackaged Magnesium-Based Alloy Sacrificial Anode For Cathodic Protection


The use of magnesium sacrificial anodes for cathodic protection is an effective method to prevent metal corrosion. Magnesium alloy sacrificial anodes have the following characteristics: good corrosion resistance, no external DC power supply, automatic operation after installation, no maintenance, and less floor space , the project cost is low, and there is no interference with the external environment. Magnesium sacrificial anodes are widely used in petroleum pipelines, natural gas, gas pipelines and storage tank; port, ship, subsea pipeline, drilling platform; airport, parking lot, bridge, power plant, municipal construction, water treatment plant, petrochemical plant, smelter, corrosion protection of gas station, water heater, heat exchanger, evaporator, boiler and other equipment.

The pre-packaged magnesium alloy sacrificial anode body is mainly composed of a magnesium alloy sacrificial anode, a special heat shrinkable sleeve, and a cable. The anode body adopts a packing material with the required composition installed around the magnesium anode body. The pre-packaged magnesium alloy sacrificial anode was developed to simplify the rapid on-site construction procedure. The original operation on the construction site is completed in the factory, which effectively guarantees the construction and installation quality of the magnesium anode bed.

The distance between the sacrificial anode (magnesium anode) groups on the pipeline is 1 to 2 groups/km for long-distance pipelines, and 200 to 300 groups are appropriate for urban pipelines and internal pipeline networks.

1. Transportation

Seat frame, armrest, small table panel, pedal, in-built profiles, driving frame, sleeper frame work, dashboard frame work etc.

2. Electronics

Magnesium alloys have excellent thin wall casting performance. They wall thickness of magnesium alloy die castings can reach 0.6-1.0mm, and the die castings can remain certain strength, stiffness and impact resistance. These performances are very consistent with development demand of lightweight, thin short and small for laptop. Mobile phone, digital camera, that makes the application of magnesium alloy grow sustainably.

3. Aerospace industry

Engine shell, parts. Skin and cabin, frame, holder, wingtip, aileron, fuel tank, gearbox, airscrew, seat, undercarriage, all kinds of shell, siding, clapboard etc.

4. Military industry

Panzer tank vehicle, torpedo, guided missile, aircraft / spacecraft, military electronic equipment, military statellite.

5. Medical industry

Medical device and implant material.
