化工设计常用管道仪表流程图物料代号和缩写词-兰州设计院

实用标准文档管道仪表流程图物料代号和缩写词1996-12-15发布 1997-01-01实施中国石化兰州设计院目次1 说明 (1)2 管道仪表流程图上的物料代号 (1)3管道仪表流程图上的缩写词 (6)附加说明 (30)1 说明1.1在本规定中列入的物料代号和缩写字母是最基本的。

当工程设计中需要补充本规定所列以外的物料代号和缩写字母时，不要与本规定相矛盾。

1.2 当必须指明物料代号是供给或返回时，可在物料代号后加S(Supply)表示供给，加R(Return)表示返回。

例如，本文中冷却水供水为CWS，冷却水回水为CWR。

1.3 要指明气相或液相等相特性时，可在物料代号后加G(Gas)表示气相，加L(Liquid)表示液相，例如氨作为冷冻剂，AMG为气氨，AML为液氨。

1.4本规定中，不包括自控专业用的代号和缩写字母，不包括计量单位和符号，不列入单位、协会、标准等的缩写字母。

2 管道仪表流程图上的物料代号2.1分类物料代号用于管道编号，分为工艺物料代号及化学品、辅助物料和公用物料代号两类。
