Abstract
FIELD: pipe line transports; shutting of end sections of pipe lines in conducting tests and repair jobs. SUBSTANCE: shut-off device includes flanges connected by means of axial rod with circular taper sleeve made from stiff material located between them; this sleeve is engageable with flexible sleeve. Ring sleeve is provided with radial cut; parts adjoining this cut are movably connected in overlap; diameter of sleeve is less than inner diameter of pipe line in free state. On opposite side of flexible sleeve, second sleeve with radial cut is provided; their thicknesses are selected within range of definite approximated relationships. EFFECT: enhanced reliability of sealing.
