摘要

The steel piping with plastic insulation for transport of liquid or gaseous media, in particular, natural gas incorporates insulated shaped components (3) welded to pipe ends (1, 2, 10) at a branch point so that only the weld zones (7, 8, 9) have to be re-insulated. These zones with multi-layered insulation are externally covered by shrunk-on sleeves (11, 12, 13).
