摘要： The invention concerns a press for the testing by means of internal pressure of tubes provided with threaded ends, in which end pieces screwed in a pressure medium-tight manner on the tube ends are inserted into the sealing heads of the press. The end pieces are cap-like and have radially arranged connecting boreholes so that the pressure medium feed is radial in contrast to the axial pressure medium feed of the familiar constructions. No appreciable axial forces thus arise between the tubes and the test heads. In addition, the outer end of the cap-like end pieces facing away from the tube serves for the coupling of a shaft, which can displace the tube with the end piece axially and act upon it with a torque. Furthermore, the sealing head is readily detachable in a like manner in a retaining head and is inserted pressure medium-tight to the outside, just as the end pieces in the sealing heads.

摘要： Apparatus for laterally ejecting elongate articles, such as tube lengths, from a channel defined by a roller bed, the channel extending beyond a flying saw for severing continuous lengths into said elongate articles, said apparatus being operated by a signal generator fitted to the flying saw so that an ejection operation is initiated by an optional delay after completion of a severing operation. Operation is not impaired in the event of the tube being fractured during the rolling operation, since the ejection operation takes place in timed relation to the severing operation and does not depend on detection of the presence or absence of tube ends.

摘要： In a method of rolling tubes in a stretch-reducing rolling mill having a group drive in which the elongation, and therefore the tension is increased by increasing the speed of an auxiliary drive motor relative to that of a main drive motor, the length of the trailing "thickened end", which must be rejected as scrap, is reduced by increasing the elongation from the point in time at which the start of the trailing end portion of the tube reaches the last stand. This trailing end portion is that portion which receives a larger wall thickness than the central portion of the tube as a result of the reduced tension exerted in the trailing end portion of prior art practices. The start of this trailing end portion can be predicted from experience or by rolling a sample tube without subjecting its trailing end portion to the said increased elongation and measuring the wall thickness at the trailing end portion of the sample tube.

摘要： A rolling mill roll and method of rolling tubes is provided in which the roll has an annular concave working surface in the outer periphery, said surface having a central annular concave portion of a preselected arc and a pair of side edge annular concave portions on each side of said central portion, said side edge portions having an arc of greater radius than the central portion and thus of lesser curvature than the central portion.
