An integrated transverse rolling mill for rolling seamless tubes with skewed axes comprising a piercing stand () with skewed axis rolling rolls for piercing a first tube () having a first length which is shorter than the space which separates it from the subsequent finishing stand () in cooperation with the stake (), which has the first piercing tip () at its end and the second finishing tip () at the finishing stand (). The finishing stand () is arranged downstream of the piercing stand () so that during the rolling operations the front end of the first tube () may only be gripped by the finishing stand () once the rear end of the first tube () is no longer gripped by the rolling stand ().

Integrated transverse rolling mill for seamless tubes

A rolling mill stand and related rolling mill for rolling rod-shaped bodies, even large in size, which meets the requirement of stiffness uniformity of the rolling mill stands in the transversal direction, all the hydraulic capsules being firmly fixed to the external structure of the rolling mill and providing for the side change of the rolls of each stand. The arrangement of rolling rolls and related extensions of each rolling mill stand is such to avoid problems of corrosion and damaging to the extensions themselves and to the reducers due to the drainage of the cooling waters.

An apparatus for recovery of tritium from contaminated gaseous mixtures by way of isotope-exchange processes includes a container having a preferably cylindrical shape made of steel or other suitable metal or glass, referred to as 'module' (), which contains at least one permeator tube (T) made of metal or metal alloy selectively permeable to hydrogen and its isotopes, wherein the tube (T) is set in cantilever fashion with its free end closed, there being further provided elements for applying an axial tensile force on the free end of the permeator tube (T) and elements for electrical connection of the free end of the tube (T) to an end flange (FF) of the module () adjacent thereto.

A rolling mill of rotating expander type for tubular bodies, comprising: working rollers () arranged inclined with respect to the rolling axis; a tip () fitted on a beam (), so that the tubular body is pushed in rotation between the rollers and the tip, and subjected to deformation in order to increase the perimeter; a tip-stabilizing system placed behind said tip, about the beam, and integrated in the rolling mill.

The invention relates to a rolling mill for tubes, in which a series of roll-holder containers () is housed in an external structure () extended along a rolling axis (L); the containers can slide inside the structure to be extracted therefrom and each one houses at least three rolls () controlled by respective driving motors (). In accordance with the intervention the rolls () can be moved inside the containers () in a guided way along directions radial in relation to the rolling axis, in order to regulate the distance therefrom.
