The invention relates to an insulated pipe for a chimney conduit, intended to guide the flow of the combustion gases, especially in industrial or domestic heating installations. The insulated pipe comprises complementary connections which can be interlocked at each end and is formed from a double wall (2 and 3). According to the invention, the walls (2 and 3) have isolating distancing means which ensure the continuity of the insulation over the entire length of the pipe (1). These distancing means are in the form of annular spacers (4) made from ceramic fibre and held axially by stops. The invention relates to the manufacturers of heating equipment. <IMAGE>
