Connecting pipe, method of manufacturing a connecting pipe

摘要

The invention relates to a connecting pipe (100) for a connecting line for the passage of smoke from a fireplace into a chimney, the connecting pipe (100) being an outer pipe (120) arranged coaxially with a longitudinal axis (LA) and one coaxial with the longitudinal axis (LA ) in the outer pipe (120) at a distance (A) radial to the longitudinal axis (LA) of the outer pipe (120) arranged inner pipe (110) for the passage of smoke and an insulating means arranged between the inner pipe (110) and the outer pipe (120) (130) for the mechanical connection of the inner pipe (110) to the outer pipe (120) and thermal insulation of the inner pipe (110) from the outer pipe (120), wherein in a male end section (101) of the connecting pipe (110) along the longitudinal axis ( LA) no insulating means (130) is arranged, and wherein the connecting tube (100) has a female end section (102) opposite the male end section (101) along the longitudinal axis (LA) for receiving the male ichen end section (101) of a similar connecting pipe (100) for the smoke-tight connection of the two connecting pipes (100). Between the inner pipe (110) and the outer pipe (120) and on the inner pipe (110) or on the outer pipe (120) there is at least one reinforcement means (140) for reinforcing the inner pipe (110) or the outer pipe (120) radially to the longitudinal axis ( LA) attached, the insulating means (130) being pressed together between the reinforcing means (140) and the outer tube (120) or the inner tube (110) for mechanical fixing of the insulating material (130), inner tube (110) and outer tube (120). ]
