This cooling jacket dilated

摘要

P is fitted a cylindrical sleeve 14 on a calender 12, then it is welded to the electron beam to the shell, along its length, by a weld helicoidale 28. The calender present at its stiffener of the holes of the input and output that the sleeve covers during its fitting. It pressurizes the sleeve through the hole of the input, by closing the outlet hole, in order to dilate the sleeve between the turns of the weld, so that it forms a series of passages 16, a semi - circular section, of a fluid duct. / p & & p & such a jacket is dieters for the cooling of a control of the bars of the control of the reactor resonance. / p
