Material code HG 20519.36-92 1 Preparation method Material code HG 20519.36-92 The material code is composed of the initials of the English noun according to the name and status of the material. Generally, 23 capital letters are used to represent it. Process material code Process air Process gas Gas-liquid two-phase flow process material Gas-solid two-phase flow process material Process liquid Liquid ring two-phase flow process material Process solid Process water 3Auxiliary and public engineering material code (1) Air Compressed air Instrument air (2) Steam, condensed water (3) Water High-pressure steam (saturated and or slightly superheated) High-pressure superheated steam Low-pressure steam (saturated or slightly superheated) Low-pressure superheated steam Medium-pressure steam (saturated or slightly superheated) Medium-pressure superheated steam Steam condensate Heating steam Boiler feed water (4)FuelwwW.bzxz.Net (5)Oil (6)Refrigerant (7)Others Chemical sewage Circulating cooling water return water Circulating cooling water supply water||tt ||Desalted water Drinking water, domestic water Firefighting water Hot water return water .Hot water supply Raw water, fresh water Production waste water Fuel gas Liquid fuel Solid fuel Natural gas Fuel oil Packing oil Lubricating oil Seal oil Gas ethylene or ethane Liquid ethylene or ethane Freon gas Freon liquid Body Gas propylene or propane Liquid propylene or propane Frozen brine return water Frozen brine water supply Drainage, drainage Flare exhaust gas Heating oil Inert gas Vacuum exhaust gas 4 Material code usage and supplementary provisions According to the specific circumstances of the project, the auxiliary and public engineering system material codes can be used as process material codes, and new material codes can be appropriately supplemented, but they must not be the same as the material codes specified above. For example, in a device that uses natural gas as raw material to produce synthetic ammonia, the process material code supplementary provisions are as follows: AG gas ammonia AL liquid ammonia AW ammonia water conversion gas natural gas synthesis gas Tip: This standard content only shows part of the intercepted content of the complete standard.
