压力容器制造的初期,需要排出钢板的下料图。设已知钢板的集合 S(s_1,s_2,s_3,…),技术要求如下:a.每张板长应大于800毫米。b.相邻环焊缝距离应大于500毫米。c.开孔及其加强板焊缝应错开壳体焊缝50毫米以上。d.设备内件与筒节焊接的焊接边缘与壳体焊缝应不小于筒体壁厚且不小于50毫米(不考虑纵焊缝);
At the beginning of the manufacture of the pressure vessel, it is necessary to discharge the drawing of the steel plate. Given the set S(s_1,s_2,s_3,...) of known steel plates, the technical requirements are as follows: a. Each plate length should be greater than 800 mm. b. The distance between adjacent girth welds should be greater than 500 mm. c. Holes and their reinforcing plate welds shall be staggered by more than 50 mm from the shell weld. d. The welding edge and shell weld of internal equipment and tube joints shall not be less than the wall thickness of the cylinder and not less than 50 mm (not including longitudinal welds);
