ASTM B843 Ribbon Magnesium Metal Alloy Anode For Underground Cables
ASTM B843 Magnesium Ribbon Anode Used For Underground Cables Protection
Introduction:
The magnesium ribbon sacrificial anode is produced with high quality and high purity magnesium. The product conforms to the ASTM97-98 standard and is extruded by a specific process. The magnesium ribbon sacrificial anode (referred to as: magnesium ribbon anode) has excellent electrochemical performance. The shape of the magnesium ribbon anode Flat, adjustable in length, easy to bend. This product is used for high resistivity environment, protection of pipelines in casings, temporary cathodic protection of pipelines, protection of storage tanks and pipeline networks, and grounding grids against strong electrical interference.

Advantages:
From raw materials - semi-continuous magnesium alloy rods - extrusion - forming, the factory is independently produced and the internal composition is controllable. Extruded ribbon magnesium anode, very flexible. Due to the higher area-to-weight ratio of the magnesium ribbon, it can provide higher current output than other anodes.
Application:
Magnesium Ribbon Anode used in high resistivity environments, protection of pipelines in casings, temporary cathodic protection of pipelines, protection of storage tanks and pipe networks, grounding grids to prevent strong electrical interference, etc.
