MMO Tubular Anode

Elade’s MMO tubular anodes can be made singly or in strings, the substrates are using of seamless titanium tubes which meet standard of ASTM B338 in Grade 1 or Grade 2 Chemical Composition.

Elade’s MMO tubular anodes coating are consisting of Precious Mixed Metal Oxides IrO2-x and Ta2O5, it has been proven to have a good performance within the design life. The coating thicknesses are designed base on application environment and tested by X-Ray and the life span are verifying by Acceleration life test which conducts in Elade’s test laboratory for each batch of goods. Elade anodes also have been tested by USA third party test laboratory according to NACE standard TM0108-2008, the test result turned out to be very excellent.

Tubular anode is used for the soil, fresh water, sea water and mud, or the other natural environments, it could be used alone or make it a string. Various tubular anode available as requested.

Titanium Substrate:

Meet ASTM standard B338 Grade 1 or Grade2.

Tubular Anode Parameter:

For Fresh water, Calcined petroleum Coke application:

For Sea water application:

Design current density under different electrolytes:

Tubular Anode Cable Selection:

PVDF,HMWPE,HALAR,XLPE,PVC or KYNAR are all optional,

 Elade recommends dual-insulated cable, such as PVDF/HMWPE cable for use where anodes operate in groundbeds high in chlorides - resulting in chlorines gas generation. Where chlorides are not anticipated, such as shallow vertical and horizontal surface beds, an economical cable choice is HMWPE.  The high current capacity (150 amps) and flexibility of the Exane Rig cable makes it ideal for seawater applications.

Tubular Anode Applications: 

Ground beds: (Deep,Shallow or open hole);

Sea Water;

Brackish Water;

Fresh Water;

Working Environment: Including soil, carbonaceous backfill, fresh water, brackish water, and seawater.

Advantages:

High current output and low electrical resistance;

Using tubular anodes can save 15-35% of install cost comparing to use other anodes;

Anode-cable assemblies are easy to handle, transport and install because of their unique flexibility;

Tubular anode cable are easy to handle, transport and install because of flexibility;

Lower cost per amp;

Guaranteed electrical contract and moisture seal integrity;

Consistently low resistance anode;

Ordering Information:

When ordering tubular anodes from Elade, please specify the following:

· Anode Type (for example, length,diameter…).

· Number of anodes per string.

· Center-to-center spacing between anodes along the cable.

· Cable tail length (above the top anode).

· Total cable length (sum of lengths of anodes, spaces and tail).

· Current output.

· Number of centralizers required and hole size.
