MMO Tubular String Anode for Pipeline Cathodic Protection

MMO Tubular String Anode for Pipeline Cathodic Protection

The tubular configuration of MMO tubular provides a larger surface area, which in turn permits greater current output and lower anode-to-electrolyte resistance. The tubular style also means lead wire connections can be made in the center of the anode. This connection is protected from moisture intrusion by a waterproofing sealant, which fills the entire anode tube. The ends of the anode are then covered with shrink tubing for a completely sealed electrical connection. In soil and freshwater applications, the anodes have a recommended current density of approximately 100 amp/m2 and can be operated over 500 amp/m2 in seawater environments. Even at these relatively high discharge levels, the anodes will be consumed at less than 1.0 mg/ampyr.
