ABSTRACT:
Insulated pipes are generally bared of insulation at their ends in order to make joints, for example welds, between the pipes. A reinsulating method and assembly is provided for the bared joints, wherein a support comprising a coiled member, for example a helical coil, is positioned around the pipe, a recoverable cover recovered into engagement with the support, and thermally insulating material introduced between the cover and the pipe. The invention is suitable for straight, T, and bent joints.
