Purpose of the band pipe aluminum sacrificial anodes
The band pipe aluminum sacrificial anodes are intended for anti-corrosion protection of the underwater part of pipe structure buildings operated in climatic zones P9-P11 in accordance with GOST 16350. The products are made of aluminum alloy. Zinc AP4N is also included in the composition of the manufacture material, due to which the normal operation of the sacrificial cathodic protection in an aggressive environment is ensured.Description of the P-BTA
The sacrificial anode is a semi-cylinder mold made of a sacrificial alloy on a steel strip reinforcement (core). The reinforcement cage is made of a strip of steel grade St3 and coated with zinc. Longitudinal reinforcement is made of 20x4 mm strip in accordance with GOST 103-76. On the unload sides of the sacrificial anode, an insulating coating made of epoxy putty GOST 28379-89 is applied in two layers. It is possible to apply any other insulating coating at the request of the customer.Operating principle of the band sacrificial anodes
The operating principle of sacrificial cathodic protection is to create a protective potential when current flows in a galvanic pair of a structure-sacrificial anode.The sacrificial anode is the anode and the structure is the cathode. The current flowing from the sacrificial anode enters the structure and suppresses or limits the action of corrosive elements on its surface, and, consequently, prevents corrosive destruction of the structure. The stationary potential of the protector along the normal hydrogen electrode is not less than 900 mV, the operating potential is not less than 850 mV. The operating electrode potential of aluminum protector alloys is not more than minus 1.05 V relative to the silver chloride reference electrode. Actual current output of aluminum sacrificial alloys is not less than 2500 A hour/kg. Aluminum alloy protectors, when disconnected from the protected structure, shall not be passivated and, when reconnected, restore the operating potential.
