(续2007年第3期)3.2.4设计载荷状况共有7种载荷状态可供设计考虑,以TEMA标准为基础,各种载荷的引用编号相同。7种载荷状态为:①仅管侧作用有压力,不考虑热膨胀;②仅壳程侧作用有压力,不考虑热膨胀;③管侧和壳侧同时作用有压力,不考虑热膨胀;④仅受热膨胀作用;⑤仅管侧受压力作
(Continued 2007 Issue 3) 3.2.4 Design Load Conditions There are 7 load conditions for design consideration. Based on the TEMA standard, the reference numbers for all loads are the same. The seven loading conditions are as follows: (1) only the pressure on the side of the pipe is used and the thermal expansion is not taken into account; (2) only the pressure on the side of the shell side is exerted and the thermal expansion is not taken into account; (3) the pressure acts simultaneously on the pipe side and the shell side, Role; ⑤ only by the pressure side of the tube
