Low Consumption Rate MMO Tubular for cathodic ptotection in fresh water environment
Jun 08, 2017

       Equipped with professional factory, Taijin Industrial is the biggest China manufacturer, supplier and producer of mmo tubular anode. Our company can offer you corrpro vendor pipeline cathodic protection, pipeline anode, pipeline corrosion protection, pipe cathodic protection at competitive price.

       Hazardous product pipelines are routinely protected by a coating supplemented with cathodic protection. An impressed current cathodic protection system (ICCP) for a pipeline consists of a DC power source, often an AC powered transformer rectifier and an anode, or array of anodes buried in the ground (the anode groundbed).

        to protect a pipeline we can use Tubular anodes

        Tubular anodes are manufactured using titanium which meets ASTM B338 grade 1 or 2 standards.

 

        MMO tubular anodes have an extremely low consumption rate. The titanium substrate remains constant throughout the design life of the anode.

 

       The anodes are resin filled and helium tested for an effective seal of the connection. The cable end of the anode is protected with a teflon sleeve. Tubular anodes are centre connected and tested for resistance (less than .001 ohms). A variety of cable types and sizes are available. Several anodes may be fitted to a single cable to form a string of anodes for use in deepwell groundbeds.
