5.3.3.1 Create/Revise Piping Commodity Specification Data
Data
The Create/Revise Piping Commodity Specification Data form is used to create or modify the definition of a piping commodity within a specified piping materials class. When creating a new definition, the system will jump to the input fields for the mandatory data. You must specify a value (by keyin or selection from a list) for all the mandatory fields.
Field Descriptions
Refer to RDB Options File, page 105, for information on defining options for the applicable input fields.
Refer to Piping Commodity Specification Data (202), page 67, for information on the attributes for the Piping Commodity Specification Data table.
Where possible, the system verifies that the specified value is valid for the applicable piping materials class. For example, NPD values are checked against the associated diameters table in the approved Piping Job Spec Table Library.
Commodity Type — This field can be used to select the type of piping commodity
data to be created based on the settings in Standard Note Type 990 of the Standard Note Library. General Fittings Pipe Bends Orifice Flanges Branch Nipples Branch Reinforcement Valves Piping Tubing Gaskets Bolts Nuts
The system will modify the form fields to reflect the data that is specific to that type of component. The system stores the commodity type as the input_form_type within the Piping Commodity Specification Data Table of the Material Reference Database.
Reference Data Manager Reference Guide — April 2002
________________
Any input fields that are not used for a specific piping commodity type will be de- activated. The General Fittings category will allow input in all the input fields. This form is used for any piping commodity that does not fall within any of the other types.

Commodity Name (keyin) From NPD - First Size (keyin) To NPD - First Size (keyin) End Preparation - First Size (list)
Pressure Rating - First Size (keyin) — This data is automatically set to undefined
(blank) for the branch reinforcement commodity type.
Table Suffix - First Size (list)
Schedule/Thickness - First Size (list) — Attribute 10. This data is automatically set
to undefined (blank) for the branch reinforcement commodity type.
Commodity Code (keyin) — Key in the commodity code for the piping commodity.
When size-dependent commodity codes are required, this will represent a system commodity code and will be used by the Report Manager to reference the size- dependent commodity code in the Piping Commodity Size-Dependent Material Data Table.
The system automatically translates the specified commodity code to be upper-case. You can use the Implied Data option to specify implied data for this piping
commodity. Refer to Commodity Implied Data Command, page 140 for information on project-specific implied data. Refer to Implied Data, page 126 for information on class-specific implied data. The default is that implied data does not apply.
For the revise command, the prefixes for implied data are not displayed as part of the commodity code, although the prefix will be loaded in the database. For implied data (project-wide or class-specific), the system will display the toggle setting rather than showing the prefix in the commodity code field.
Model Code (keyin or list) — Attribute 19. Key in the model code or select the model

Define the following data for any reducing components. This data will not apply to either the orifice flange or branch nipple commodity type.
From NPD - Second Size (keyin) — Attribute 12. Key in the lowest second size for
which this specification data applies.
To NPD - Second Size (keyin) — Attribute 13. Key in the highest second size for
which this specification data applies.
You can optionally define the following fields when two ends of that component require different data. By PDS convention, if you specify a red End Preparation, you must specify the corresponding pressure rating, table suffix, and schedule/thickness.
End Preparation - Second Size (list)
Pressure Rating - Second Size (keyin) — This data is set to undefined (blank) for the
branch reinforcement commodity type.
Table Suffix - Second Size (list)
Schedule/Thickness - Second Size (list) — This data is set to undefined (blank) for
the branch reinforcement commodity type.
The following data must be defined for the designated [component types]. The setting is stored in the modifier attribute.
Bend Radius (keyin) [Pipe Bend] — Key in the bend radius for the pipe bend. Number of Taps (toggle) [Orifice Flanges] — Set the toggle for the number of taps (1
or 2) on the orifice flange. If applicable, set the orientation of the taps as 90 degrees or 180 degrees. This toggle only appears for orifice flanges that have two taps.
Nipple Length (keyin) [Branch Nipples] — Key in length of the branch nipple. Reinforcement Data (toggle) [Branch Reinforcement] — Set the toggle for the source
of the branch reinforcement data to By System or By User.
If you select the by user branch reinforcement option, the commodity option code is automatically defined with a value of 699 (User-defined), as required by PDS.
Valve Operator (keyin or list) [Valves] — Key in the valve operator type or select the
valve operator type from a list of valve operator types. The list of valve operator types and the corresponding descriptions are defined in the RDB options list.
Valve Operator Display (toggle) [Valves] — Set the toggle to ON or OFF to
determine whether the valve operator is displayed in the model.
Modifier (keyin) — You can define this value for specific piping commodities not

You can define the following optional data depending on your requirements.
Commodity Option (list) — Attribute 4.
Max Temperature (keyin) — Attribute 5. If no value is specified, the default value
(undefined) is assigned automatically.
Materials Grade (list) — Attribute 25.
Standard Note Number (list) — Attributes 26 and 27. Select the note for this
commodity from the list of standard notes defined in the approved Standard Note Library.
PDS Sort Code (keyin) — Attribute 20. The specified value is automatically converted
to upper-case.
Specification data for piping
You must define the following data for piping. The piping commodity name is defined automatically, as specified through the Project Data Manager.
From NPD - First Size (keyin) To NPD - First Size (keyin) End Preparation (list) Pressure Rating (keyin) Table Suffix (list) Schedule/Thickness (list)
Joint Quality Factor (keyin) (For wall thickness calculations) — In lieu of the
schedule/thickness, you can request that the wall thickness be computed automatically by the system by specifying the joint quality factor for wall thickness calculations. The system multiplies the joint quality factor by 100, add a *C prefix to designate that the default calculation is to be used, and loads the value into the schedule/thickness column. For example, if the joint quality factor is 0.95, this value will be ’*C095’. Note that this is not the joint quality factor that is to be used in the branch reinforcement calculations.
