Abstract

Insulation and protection system comprises >=2 successive windings of a continuous elongated strip formed from a flattened knitted metal tube. The tubular strip has transverse openings connecting its interior and exterior and permitting the insertions of the successive, thin metal sheets extending longitudinally along the strip. Pref. the two windings cross each other, the second winding being displaced by half the width of the strip relatively to the to the first winding. Even if a failure of the pipe occurs, outward projection of the liq. it contains does not occur, while the insulation as such has an extended length of life.
