ABSTRACT:
An anode arrangement for use in the internal cathodic protection of a pipe includes a hollow anode-carrier member to be connected along the length of the pipe and to form a continuation of the channel defined by that pipe and further includes an anode mounted in the recess of the carrier member, the anode being offset from, but communicating with, the channel of the pipe so that the anode lies substantially wholly within the recess and does not obstruct the flow in the pipe.
In a preferred construction the anode is mounted on a cover plate of the carrier member so that the anode can be removed from externally of the channel of the pipe.
