Piping Materials Class Data Command

The Piping Materials Class Data command can be used to create a piping materials class definition in Table 201 of the Material Reference Database or revise and existing piping materials class definition.

Options

Create — The system activates the Create Piping Materials Class Data form. Revise By Keyin — The system activates the Revise Piping Materials Class

Data form. Key in the name of the piping materials class to revise in the

Piping Materials Class field.

Revise By List — Select the piping materials class to be revised from the

displayed list of piping materials classes (as defined in the Unapproved Material Reference Database) and select Accept. The system activates the Revise Piping Materials Class Data form with the data for the selected piping materials class.

Create/Revise Piping Materials Class Data

The Create/Revise Piping Materials Class Data form is used to create or modity the definition of a 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 for all the mandatory fields.

Field Descriptions

The system highlights the mandatory input fields (those that must be specified). Once you define a valid input for a mandatory field the system will drop the highlight for that field. Refer to RDB Options File, page 105 for information on defining list options for the applicable input fields.

Refer to Piping Materials Class Data (201), page 62 for more information on the attributes for the Piping Materials Class Data table (201).

Create/Revise Piping Materials Class Data

________________

Gasket Table (keyin or list) — Key in the table name or select from the list of tables

(as defined in the approved Piping Job Specification Table Library). The list of Gasket Separation Tables will exclude the pressure rating value.

Service Limits (keyin or list) — Key in the name of the Service Limits Table for this

piping materials class or select from a list of Service Limits Tables (as defined in the approved Piping Job Specification Table Library).

Diameter (keyin or list) — Key in the name of the Nominal Piping Diameter Table for

this piping materials class or select from a list of Nominal Piping Diameter Tables (as defined in the approved Piping Job Specification Table Library).

Branch Table (keyin or list) — Key in the name of the Branch Table for this piping

materials class or select from a list of Branch Tables (as defined in the approved Piping Job Specification Table Library). The list will only include the unique tables, where the branch angle is 90 degrees.

You should not assign the same Branch Table to be used in two different piping materials classes if, for example, one allows intersections at both 45 degrees and 90 degrees, and the other only allows 90 degree intersections. The Reference Data Manager will detect this problem.

Tap Data (keyin or list) — Key in the name of the Tap Properties Data Table for this

piping materials class or select from a list of Tap Properties Data Tables (as defined in PDtable_205 of the unapproved Material Reference Database).

The unapproved tap properties data is referenced, since all specification data within the Material Reference Database is approved in one operation.

Optional Data - Wall Thickness

This data is required for piping commodities, where the schedule or thickness is not explicitly defined in the piping materials class or in a wall thickness table.

Corrosion Allowance (keyin) — Key in a numeric value, if wall thickness calculations

are to be used.

Thickness Equation (list) — Select one of the displayed wall thickness equations.

ANSI B31.3-1987 EL01 ANSI B31.1a-1986 EJ01

The corresponding name for the thickness equation is loaded into the Piping Materials Class Data Table.

Thickness Table (keyin or list) — Key in the name of the Thickness Data Table for

this piping materials class or select from a list of Thickness Data Tables (as defined in the approved Piping Job Specification Table Library).

________________

Materials Data Table (keyin or list) — Key in the name of the Materials Data Table

for this piping materials class or select from a list of Materials Data Tables (as defined in the approved Piping Job Specification Table Library).

Optional Data

The following data is not not required and can be defined or not defined based on your company practices.

Materials Description (keyin or list) — Key in the numeric value for the materials

description in the Standard Note Library for this piping materials class or select from the list of materials descriptions (as defined in the approved Standard Note Library).

Revision (keyin) — Key in up to two alphanumeric characters for the revision number. Revision Date (keyin) — Key in up to ten alphanumeric characters for the date. The

current date will not be entered automatically.

Note that the Reference Data Manager creates and maintains a separate revision management date on the basis of the current date and time which can be used in the reporting of reference data.

Fluid Code (keyin list) — Define a default fluid code to be used for the piping

materials class.

— OR —

Fluid Code Table (keyin list) — Key in the name of the Fluid Code Table for this

piping materials class or select from a list of Fluid Code Tables (as defined in the approved Piping Job Specification Table Library).

Materials of Construction (keyin) — Key in upt to six alphanumeric characters. Bend Deflect Table (keyin or list) — Key in the name of the Bend Deflection Table

for this piping materials class or select from a list of Bend Deflection Tables (as defined in the approved Piping Job Specification Table Library).

Pipe Length Table (keyin or list) — Key in the name of the Pipe Length Table for this

piping materials class or select from a list of Pipe Length Tables (as defined in the approved Piping Job Specification Table Library).
