求高手帮忙翻译一下? 先抛一个石头、砖什么的出来,不妥的地方请大家慢慢改。。。 1.preferred orientation is given first ,other allowed orientations are given after a/. (管线布置)先采用首选走向,其次采用其它的可允许走向。 2.process line orientation can be horizontal or vertical 工艺管线可为水平或竖直布置。 3.condensing vapour service lines are to be horizontal .2-phase lines to be horizontal with s/b tapping to ensure at low point .liquid lines and non condensing vapour service to be horizontal or vertical. 发生冷凝的气相管线应水平布置,两相流管线水平布置并在低点开孔,液相管线和不发生冷凝的气相管线既可水平也可竖直布置。 4.sample tapping orientation can be top,bottom or side. 取样可在顶部、底部或侧面开孔。 5.selected orientation to be filled in by detailed engineering contractor. 详细设计承包商应参与布置走向的选择。 6.condensation possible .sample line to be free drain from first isolation valve back go main process line .isolation valve must be easily accessible. 可能发生冷凝的样品管线应可从第一个切断阀处放净。(back go)主要工艺管线的切断阀必须便于操作。 7.type ss means 'special' .each ss sample is different .for details refer to the sample point details document number 2177-00-t2-z8. ss型为‘特殊件’。每个特殊件各不相同。详情请参照取样点详解(文件号2177-00-t2-z8)。 8.sample for sulphur analysis .use inert tubing :sulfinert or silcosteel ptfe-lined stainless steel tubing can be used when sampling processes 硫分析的取样需用惰性管材:取样时可用硫钝化或硅钢(聚四氟衬里不锈钢管)。查看更多
