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.

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
