Nozzle Specification

Catalogues and Specifications User Guide

Equipment : Nozzle Specification

Use the Nozzle Specification window to build up a specification by reference to the attribute settings of existing nozzles in the catalogue database. The specification simply acts as an index to allow any required nozzle to be located easily.

Note:

The functionality is only available in the EQUIPMENT discipline and at least one Specification World with its PURP attribute set to indicate its suitability for storing nozzle specifications has been created. Set the purpose for NOZZLE spec to EQUI, and the SPEC purpose set to NOZZ.

To build such a specification, navigate to the catalogue element (CATA, SECT or CATE) that contains all nozzles that are to be accessed using the new specification.

Use the upper part of the window to specify details of the overall SPEC element to be created; the lower part lists all nozzles below the current level in the catalogue which can be used to specify which ones are to be included in the specification.

If required, change the default settings for Spec, Description and Standard.

The Spec World option lists all available SPWL elements for the appropriate generic type (as controlled by the setting of the PURP attribute). If more than one is available, select the one below that the new SPEC element is to be created.

The left-hand list is populated with the category (CATE) elements, while the right-hand list is populated with the nozzles in the selected category. By default, all listed nozzles are incorporated into the specification. To prevent one or more nozzles or complete categories being included in the specification, select them in the relevant list and click Remove below that list. The 'removed' entries will only be shown (marked with a * symbol) if the Hidden option above the list is set to On. To reverse the process, select a 'removed' entry and click Re-Instate.

When the lists are populated with only those nozzles which can be selectable using the new specification, click OK to build the specification.

Create Specification

The Create Specification window available in the Spec Generator application is used when creating Specifications for Nozzles or Structural Steel.

While within Spec Generator, in the Create group, select Specification to display the Create Specification window.

In principle, an empty Specification element can be created and then modify it by reference to any specified catalogue item. In practice, you can only create Specifications for structural profiles or equipment nozzles using this method.

To create a Specification in this way (perhaps for later modification), check the CE is a SPWL element.

Use a meaningful Name and Description to identify the specification amongst many others.

The Generic Type option currently restricts choice to Equipment (with a corresponding Spec Type of Nozzles) or Structural Steel (with a corresponding Spec Type of Steel Sections, that is Profiles). Select the required option.
