4、1试压系统的划分本工程管道试压原则上按照“分区域、分级别、分系统、分材质”进行。按照设计及规范要求，管道安装完毕，无损检验合格，对管道系统进行压力试验。针对本工程的特点，工艺管道的施工是按区域进行安装，由于各工艺区的施工进度、介质、工艺特点不同，本工程的工艺管道水压试验拟按照区域、管道级别、设计压力、管道介质、管道材质等多种因素，并根据流程图和管道设计压力对管道进行系统划分。确保先施工完的管道系统先进行试压的原则，进行流水式试压。因本工程采暖管线已经投用，经建设单位同意，现不再进行试压。试压系统主要划分为：原料精制区系统、排放气回收区系统、排放气压缩机区系统、反应区系统、造粒区系统和工艺管廊区
5、系统等六大试压系统。每个试压系统按照管道试验压力、管道材质、管道介质进行划分试压包。每个试压系统的试压包划分如下：系统一：原料精制区系统精制区管道试压系统划分试压系统管线号设计压力（Mpa）试验压力（Mpa）系统试验压力（Mpa）A012-P-10B18-1E21/A4.0686.1026.2MPa2-P-10B04-1E21/A4.0686.1022-P-10B07-1E21/A4.0686.1023-P-10B11-1E21/A4.0686.1023-P-10B20-1E21/A4.0686.1022-P-10C01-6E57-(HC)-H2/A4.0686.1022-P-10C02-6E
