摘要
Pipe for building a thermally insulating conduit, obtained by butt welding at 131 prefabricated pipe sections or bars 11 to each other, each formed by two concentrical pipes 21, 31 connected at their ends by special cylindrical joints 41 substantially having the shape of a horizontal Y fork, the annular gap 101 being filled with thermally insulating material. Additionally the area (14, Fig. 1) external to the cylindrical joints at the butt weld can be filled with insulating material after the pipe sections are connected. The connection can readily be checked for faults and prevents any undesirable cavities being formed as might happen with conventional concentric pipe joints. IMAGE
