摘要

The method for stabilising a pipe positioned in an outer protective pipe with spacers between comprises passing a lifting and mounting device (30) through the annular space between the two pipes. This removes the spacers and replaces them with insulating supports (23, 24). An independent claim is included for a device for carrying out the process.
