Abstract RU 2191883 C2

FIELD: devices for expanding of overlapping members from shaped pipes installed in wells. SUBSTANCE: device has body with central channel and hollows on external surface. Rollers are installed in said hollows with the help of axles inclined relative to device body. Upper ends of roller axles are secured detachably in body. lower ends of rollers are installed with the help of hinges for turning in plane running through longitudinal geometric axes of device body and rollers to provide for their removal from hinges and replacement. Expanding of overlapping members is carried out after preliminary hydraulic expansion by rotation of drill pipe string to which device is connected. EFFECT: simplified design and increased operating reliability of device. 4 dwg
