Abstract

The invention comprises a pipe having a tube 12, a sleeve 14 over the outer face of the tube, a coating 18 over at least a portion of the sleeve, and an electrical connector 16 extending through the coating and attached to the sleeve. Preferably the sleeve extends circumferentially around the tube. The tube may be load bearing, and the various layers of the pipe formed from steel. The pipe preferably comprises means to attach sacrificial electrodes thereto. Also claimed is a method of manufacturing a tube and a method of launching a series of the claimed pipes.
