大型石化装置多层管廊的配管设计

PIPING DESIGN OF MULTI-LAYER PIPE RACK IN LARGE-SCALE PETROCHEMICAL PLANT

石油化工装置的大型化,使其装置内管廊的设计也日趋复杂:管廊的长度、宽度和管廊上管线的管径大大增长。管廊的结构确定、管廊上大口径管线的排布、长距离高温管线的柔性设计以及管廊顶部平台和梯子的设置成为管廊设计新的难点。笔者以某大型石化装置主管廊的设计为例,从管廊的结构设置、管廊上管道的布置以及管廊上平台的布置等方面对大型石化装置多层管廊的设计进行重点说明。

With the increase in capacity of petrochemical plants,the design of pipe rack becomes more and more complex.Taking the design of main pipe rack in a large-scale petrochemical plant as an example,this article introduces and summarizes the piping design of multi-layer pipe rack in large-scale petrochemical plant from aspects of pipe rack structure,piping arrangement on pipe rack and platform arrangement on pipe rack.
