Liner Mixed Metal Oxide Anodes For Cathodic Protection

English

Spanish

Arabic

Description:

MMO linear anodes, also known as flexible anodes, are an ideal product for use when a low-current, evenly distributed cathodic protection system is needed. The core of the anode is composed of high-grade, titanium wire with a Ir–Ta mixed metal oxide catalyst coating. The titanium wire is prepackaged in a porous, non-woven fabric "sock" that contains high conductivity calcined petroleum coke breeze -- enhancing the anodes abrasion and damage resistance.

Advantage:

The MMO linear anode has the advantage of easy installation and handling as well being cost efficient

Application:

Typical uses for this anode include the impressed current cathodic protection of in-plant piping, buried oil (gas) pipelines, petrochemical container, tank bottoms and other underground structures.
