Insulating and fixation system of steam tracers in fluid transportation pipings

Insulating and fixation system of steam tracers in fluid transportation pipings, comprising:

• an internal metallic piping with a larger diameter than a piping to be heated, said internal metallic piping arranged concentrically to the piping to be heated,
• a plurality of piping heating extensions, said internal metallic piping endowed with internal equally distant spaced ribs in the longitudinal direction for arrangement and fixation of the piping heating extensions and a thermoplastic external piping, arranged concentrically to said internal metallic piping, forming an annular space and thereby forming a double wall tubular cylinder, said annular space formed between said internal piping and the external piping being fulfilled with insulating material, said insulating material having no contact with said piping to be heated and external surroundings wherein double wall tubular cylinder has a in longitudinal bipartite configuration.
