    The invention relates to rebar reinforcement, namely to a joint sealed for external environments, for two cast iron pipes with a narrow end and a socket, and can be applied to pipes intended for transporting hot water having an outer covering for most of its length. consisting of a heat insulating layer, an external protective coating which is not permeable to the media, is bounded on the outside, and the narrow ends and sockets of each pipe are devoid of this external coating. The purpose of the invention is to improve the tightness of the joint by allowing the thermal expansion of the outer insulation coating and the pipe and the angular deviation of the center of the pipes to be joined with minimal heat loss and with a small outer coating. One of the sealing rings closes the annular space between the cast-iron pipe 3 and its outer protective sheath 11 at one end of the heat-insulating layer of one of the composite pipes and has an anchoring protrusion g

    on the outer surface of the socket 5 and radially clamped between the socket and the protective casing, as well as the gemetrical ring in the axial extension of the anchor protrusion and overlapping along c 16, When transporting hot water, the layer 10 of insulating material, the protective sheath 11 and the cast-iron pipe 3 expand. When this occurs, axial compression occurs.
