AnodeFlex™ MMO 3100 - 328mA/m (100mA/ft)
Long-line, Flexible Anode of Copper-Cored Titanium Wire
Iridium-based Mixed Metal Oxide Coating.
Pre-packaged in Coke Breeze.
328mA/m (100mA/ft) output.
Five Basic Elements
Anode comprised of Copper-Cored Titanium Wire with Iridium-based Mixed Metal Oxide (MMO) coating
- Provides low attenuation for reduced splicing, in combination with prepackaged coke breeze, offers a low resistance groundbed designed for a minimum life of 20 years at maximum current output.
Central Bus Cable: #6 or #8 AWG Halar Insulated Copper
- #6 and #8 HMWPE Insulated Copper also available
- Serves as a low resistance busbar to delivering current over distance
- Minimizes longitudinal voltage drop.
- Halar insulation seals the conductor from chemical attack;
- Halar is stable in presence of chlorine, hydrochloric acid, sulfuric acid, or strong oxidizing agents.
- Pre-Packaged Coke Breeze: Anode is centered in high performance calcined petroleum coke breeze, serving as the active matrix in which the electrochemical reactions take place. Designed for a minimum of 20 years service life at maximum current output of 328mA/m (100mA/ft).
- Patented acid resistant, porous Fabric Jacket: Integrated holds the coke breeze in place around the anode.
Protective braid: Tough, porous, non-conductive protective braid enhancing the abrasion and damage resistance of the fabric jacket.
- Anode can be remote to the pipeline
- Flexible under tank bottom design
- Long continuous circuit lengths
- Pipeline Rehabilitation without Excavation
- Pre-packaged coke breeze
Used to protect buried Pipelines and Above- or Below-Ground Storage Tanks, AnodeFlex™ 3100 can be placed remote to the target structure where protection of upto 328mA/m (100mA/ft) is designed. AnodeFlex 3100 achieves the optimum current output in applications where close proximity anode groundbeds do not work.
AnodeFlex™ 3100 can be placed remote to the steel surface to be protected, thereby maintaining the steel-to soil "instant-off" potential in the required window of -850 mV (-950 mV if SRB's present) and -1200mV. The central MMO wire and cable are surrounded by factory prepackaged, high conductivity coke breeze, held in place by a porous, woven acid-resistant jacket. This arrangement avoids handling loose coke breeze and simplifies field installation. The patented use of acid resistent jacket maintains longterm integrity of the anode's coke breeze. The improved current distribution increases anode efficiency and maintains a low resistance groundbed. On poorly coated pipelines where optimal polarization can no longer be achieved, AnodeFlex™ 3100 can often be installed as an alternative to expensive recoating. Both on single and multi-parallel pipelines, safe levels of polarization will be restored at every point. The system avoids difficult and costly field recoating and greatly reduces environmental disturbance.
AnodeFlex™ 3100 is delivered on long length spools and the installation is as simple as laying a low voltage power cable. Proven heat-shrinkable splice kits, with tee splices and end sealing caps are available to complete any installation design.
