Electrolytic interior surface treatment apparatus (100) for the electrolytic treatment of an internal surface (102) of a metallic pipe (1) includes at least two oppositely polarised electrodes (3, 4). The apparatus (100) includes: an electrically insulating centralisation arrangement (106) to keep, in use, the electrodes (3, 4) centred within the pipe (1); and an electrically insulating flexible connection arrangement (104) located between the two electrodes (3, 4) to permit movement of one electrode relative to the other. The centralisation arrangement (106) includes a plurality of spaced apart centralisation devices (5, 6). Each centralisation device (5, 6) includes an electrically insulating mounting (7) for mounting the respective centralisation device (5, 6) to the apparatus (100). Each centralisation device (5, 6) includes a plurality of flexible elements (108), each of which is fixed to the mounting (7) and extends outwardly from the mounting (7).
Electrolytic interior surface treatment apparatus for the electrolytic treatment of an internal surface of a metallic pipe, the apparatus including at least two oppositely polarised electrodes, the apparatus being arranged so that, in use, there is no direct electrical contact between the apparatus and the internal surface being treated, the apparatus including:
