ASTM Magnesium anode for cathodic protection
High potention sacrificial magnesium anode manufacturer
Hp magnesium anodes are produced in a variety of shapes and sizes for use in anti-corrosion protection of such projects are oil pipelines, gas pipelines, water supply
pipes and drain-pipes, underground cables, chemical plants,
communication, harbors, watercrafts and reservoir strobe.
Application
High Potential Magnesium anode fight corrosion effectively and
economically, and are commonly used in marine environments, soil
environment,etc..They protect a variety of steel structures in
salt, brackish and fresh water, including: Buried Oil gas
Pipelines, Storage tanks, Boats, Ballast tanks, Bulkheads, Pilings,
Heat exchangers, etc.
* Boats * Ballast tanks * Bulkheads * Water storage tanks
*Pilings * Pipelines*Heat exchangers
Magnesium anodes corrode much more easily than the materials they
are protecting, drawing the corrosion away from equipment.
