Abstract： A newly-built catalytic cracking unit in a certain enterprise experienced multiple leaks in its 304L caustic solution pipeline during the early stages of operation. Through macroscopic and microscopic analyses of the leak location， the deep-seated causes of caustic solution pipeline leaks were identified and improvement measures were proposed.

Keywords： operation; caustic solution; leakage; cause analysis; 304L material

某企業(yè)新建催化裂化裝置內(nèi)不銹鋼堿液管道在裝置開工投料不久后，即發(fā)生管線泄漏情況，此后不到一個(gè)月時(shí)間內(nèi)，該堿液管線又多次在焊縫處發(fā)生腐蝕泄漏情況，本文基于宏觀和微觀分析檢測(cè)方法，對(duì)堿液管線腐蝕泄漏原因進(jìn)行深層次分析，對(duì)于今后新建裝置酸、堿等易腐蝕介質(zhì)管線的安裝和投用方法具有一定指導(dǎo)意義。（剩余3705字）
