请问 vessel trim 什么意思? 这里应该是指罐体材质的意思。 在论坛搜索一下trim,以前讨论过。 从下面这段话看应该是'容器配管'的意思。 2) it's been some time since i worked on p&ids as a process engineer, but your understanding of the vessel trim appears correct to me. the loose piping items connected to a vessel get a linenumber including pipespec, pound class etc and that is called the vessel trim . you have to think about valves on vents, on drains or level gauges.查看更多
