MMO Titanium Anode/Conductive Strip For Cathodic Protection

MMO (precious metal oxide) anode strip (strip anode) is a titanium substrate surface coated with a layer of precious metal oxide with electrocatalytic activity, usually used for the cathodic protection of ground storage tank floor and reinforced concrete structure, generally laid vertically with the titanium conductive strip, the intersection point is spot-welded with a special welding machine, forming a grid. The power point connection is connected by special anode joint, which has become the most ideal and promising auxiliary anode material for mesh anode cathodic protection system.

How To Use

Generally, it is laid vertically with the titanium conductive strip as an auxiliary anode for impressed current cathodic protection. The intersections are spot-welded with a special welding machine to form a grid-like grid, and the power points are connected with special anodic joints, which is simple to install and convenient to construct.

Note: The service life and output current of different requirements can be designed and manufactured by adjusting the coating ratio. MMO strip anode coating type, thickness and anode specification size can be customized by the user, depending on the required current density, the medium environment used and the design life.

Application fields

Used in various large storage tank bottom protection. In applications, it can be laid directly in wet or saline sand without the need for any carbon-based filling material.

Working Environmentts Description

A: good sandy environment

B: in the environment of chlorine evolution, oxygen evolution or a mixture of both

C: usually used in the bottom of storage tanks and reinforced concrete structures.
