FIELD: process engineering.
SUBSTANCE: invention relates to metal forming, particularly, to elimination of warpage of long articles. It can be used for recovery of geometrical shape of hollow graphite columns of pressure tube reactor. Rope tensioner comprises working section secured to the rope to slide therewith, while loading mechanism is equipped with linear displacement transducers connected via sampling module with the display. Note here that it is equipped with extender to position the working section composed of the set of cylindrical elements with bores for said rope to slide thereon and having the angular and radial shifts relative to their central axes connected by retaining end contact pairs.
EFFECT: eliminated distortions of geometry of several tubes at a time.
