Tap Properties Data (205)

This table contains the tap properties data that is a function of the tap properties table name and the nominal piping diameter. These tables define the piping taps which can be added to any of the components included in a piping materials class. The system uses the information in these tables and the nominal diameter to provide values for rating, end preparation, schedule/thickness, and tap code. Tap tables do not allow a NPD range; there must be an individual entry for each tap diameter.

The NPD entry in the tap table should be either imperial units or metric units depending on the NPD requirements of the project. For imperial units, enter the specified NPD, such as 0.375. The software will provide a default unit of inches when the value is loaded into the project. For metric NPD units, enter the units after the value on the first NPD entry. For example:

! Diam Opt Rating Prp SC/Th Tap Code 10mm 1 - 591 NREQD E$37591XXX 20 691 - 591 NREQD E$37581XXX

The Tap Properties Data table contains 8 attributes. The following kinds of taps may be defined in this table:

No-hole taps that permit the subsequent placement of a pipe support trunnion. For example, a no-hole tap may be placed on an elbow or tee to allow the subsequent placement of a pipe trunnion for a pipe support; the diameter of this no-hole tap must be defined to have the same nominal diameter as the component part on which placed. Hole taps that permit the subsequent placement of piping, piping components, and instrument components. For example, a hole tap may be placed on a cap to allow the subsequent placement of a reducing component such as a flatolet; the diameter of this hole tap must be defined to have the same nominal diameter as the component part on which placed. A hole tap can also be placed on a blind flange to allow the placement of plain piping; the diameter of this hole tap must be defined to have the same nominal diameter as the plain piping.

Hole taps that permit the venting or draining of a piping and/or instrument component. For example, a hole tap can be placed on an elbow downstream of a relief valve; the diameter of this hole tap must be defined to have the same nominal diameter as the desired drain hole.

Component taps that represent a tap connection, rather than a hole. For example, a socketwelded component tap may be placed on a gate valve to represent a socketwelded connection furnished by the valve manufacturer. The diameter of this component tap must be defined to have the same nominal diameter as the desired connection.

2. tap_table_name , character(6)

This attribute identifies the name of the Tap Properties Data Table. These tables use the following naming conventions:

first character: C

next three characters: numbers from 001 through 999 used to make the table name unique.

The combination of the tap properties table name, the tap NPD, and the tap option, must be unique.

3. nominal_piping_dia , short

This attribute defines the value for the nominal tap diameter.

4. option_code , short , SN 400

This code-listed attribute identifies the option code which determines the search criteria. This parameter enables you to request that the system retrieve the primary item, a secondary item, or another special option from the Piping Job Specification. If no option is specified at placement, this attribute defaults to option 1 (primary item). This parameter is used as a component override in Piping Design.

5. end_preparation , short , SN 330

This code-listed attribute identifies the end preparation. The system recognizes a certain range of values as being flanged termination types, another range as being butt welded termination types, etc.

6. rating , character(8)

This attribute exists as alphanumeric data. The system interprets the first set of sequential numeric characters as being the pressure rating value. (Refer to the description of pressure rating for Piping Commodity Data for more information on standard formats.)

7. sched_thick , character(8)

This attribute identifies the generic or specific schedule, a thickness value, or a calculation. (Refer to the description of schedule and thickness for Piping Commodity Data for more information on standard formats.)

This attribute is also referred to as the Tap Code. Refer to the listing of the tap descriptions in the Short Material Description Library, page 367, for more information on the tap commodity code.
