Insulating and fixation system of steam tracers in fluid transportation pipings

摘要

The present invention refers to an insulating and fixation system of steam tracers in fluid transportation pipings, comprising the supply of a first internal metallic piping (50) with diameter a few larger than the piping (52) to be heated, endowed with equally spaced internal rips (54) in the longitudinal direction for arrangement and fixation of heating extensions (56) and a second external thermoplastic piping (58) being one concentrical to each other, forming an annular space (60) and presenting itself as a double wall tubular cylinder (62), said annular space (60) forming between the said first internal piping (50) and the second external piping (58) being fulfilled with insulating material (64) without any contact with the said piping (52) to be heated or external surroundings.
