Pipeline Instrument Flow Diagram Material Codes and Abbreviations HG20559.5-93
Compiled by: Process System Design Technology Center of the Ministry of Chemical Industry Approved by: Chemical Industry
Implementation Date: November 1, 1994 1.0.1 The material codes and abbreviations listed in this regulation are the most basic. When the material codes and abbreviations other than those listed in this regulation need to be supplemented in the engineering design, they should not contradict this regulation. 1.0.2 When it is necessary to indicate whether the material code is supply or return, S (Supply) can be added after the material code to indicate supply, and R (Return) can be added to indicate return. For example, in this article, the cooling water supply is CWS, and the cooling water return is CWR. 1.0.3 When it is necessary to indicate the phase characteristics such as gas phase or liquid phase, G (Gas) can be added after the material code to indicate gas phase, and L (Liquid) can be added to indicate liquid phase, such as ammonia as a refrigerant AMG for gas ammonia, and AML for liquid ammonia. 1.0.4 This regulation does not include the codes and abbreviations used in the field of automatic control, does not include measurement units and symbols, and does not include the abbreviations of units, associations, standards, etc. 515
2.0.1 Classification
2 Material codes on piping and instrumentation flow charts
Material codes are used for pipeline numbering and are divided into two categories: process material codes and chemical, auxiliary material and public material codes.
