移动式压力容器壳体最低设计金属温度及选材问题的探讨

Discussion on Minimum Design Metal Temperature and Material Selection of Transportable Pressure Vessel Shell

基于移动式压力容器的流动性特点,考虑其运营中大气环境温度的影响,相应标准规范均对其罐体最低设计金属温度给予了规定,以保证低温条件下的安全运营,但因此也引发了罐体设计选材制造等方面的问题。本文试对其进行探讨并提出建议。

Based on the fluidity characteristics of transportable pressure vessels, and considering the influence of atmospheric ambient temperature in operation, the minimum design metal temperature of vessel shells is specified in the pressure vessel codes to ensure safe operation at low temperature, but it also causes some problems in design, material selection and manufacture. This paper tries to discuss it and put forward some suggestions.
