Head Medvedev V.I., Registration Date 06-06-2007 Organization State Scientific Research Tube Institute popup.description2 It was establised that the level of wall thickness variation in hot extruded tubes, beside the wall thickness variation after drilling, is essentialy influenced by local wear of the sleeve in horizontal press and lubrication degree on the inside tube surfase. It was recommended that periodically, after 1000-1200 pressings, the sleeve was turned in a horizontal plane and optimum lubricant guantity on the shell inside surface was calculated.
