Commodity Codes
Commodity codes control several aspects of PlantWise.
| COMMODITYCODE | Fluid-Type | Op-Tmp | Des-Tmp | Temperature | Ins-Code | Trc- Type | Trc-Sz | Trc-Num | Pnt-Type | PipewayLevel | Cad-Level | Density |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| "AA" | :LIQUID | 0.0 | 0.0 | :HOT | "nil" | "none" | "None" | 0 | "nil" | :UTILITY | "blowdown" | 0.01289699 |
| "AIR" | :VAPOR | 0.0 | 0.0 | :COLD | "nil" | "none" | "None" | 0 | "nil" | :UTILITY | "air" | 1.735e-5 |
| "BD" | :LIQUID | 0.0 | 0.0 | :HOT | "nil" | "none" | "None" | 0 | "nil" | :PROCESS | "process" | 0.01289699 |
| "CHEM" | :VAPOR | 0.0 | 0.0 | :COLD | "nil" | "none" | "None" | 0 | "nil" | :UTILITY | "chemicals" | 0.01345328 |

FLUID-TYPE – determines the preferred approach
direction to tees on a pipeway and is also used in the routing of suction and
gravity feed lines.
The preferred approach of a :LIQUID commodity into a tee on a pipeway is from above.
The preferred approach direction of a :VAPOR commodity into a tee is from below.
- OP-TMP – indicates the default operating temperature of each commodity;
- DES-TEM – indicates the default design temperature of each commodity;
- Temperature (:HOT or :COLD), may determine the placement of nozzles in the nozzle placement rules. For example, a heat exchanger places the hot inlets and outlets on the top and the cold on the bottom. The temperature also determines the placement preferences of pipelines routed on the pipeway. HOT pipes are preferably all put on the same side to allow "nested" expansion loops.
- INS-CODE – is the default insulation code for pipelines of each commodity;
- TRC-TYPE – indicates if a particular commodity requires tracing of the pipeline by default;
- PNT-TYPE – indicates the default paint type each commodity requires;
- TRC-SZ – is the default tracing size required for each commodity;
- TRC-NUM – is the default number of tracings required for each commodity.
- PIPEWAY-LEVEL
(:UTILITY, :PROCESS, or another user chosen level name) determines the
preferred routing levels for pipelines carrying the commodity.
The AutoRouter places UTILITY pipelines first on the second level of a multi-level pipeway while PROCESS pipelines prefer the first level.
By default, the AutoRouter places UTILITY cables first on the second level of a multi-level pipeway while PROCESS cables prefer the first level. You can change level setting in the Pipeway Builder (see Editing Level Names).
- CAD-LEVEL – designates what level pipelines of each commodity should draw to.
- DENSITY – is used for weight calculations of an operating model.
