Bolt Table Utilities

Bolting tables are part of the bolt table hierarchy which contains information describing the nature of the bolted connections of piping components in a project. Although the Bolt Table is part of the Catalogue database, and so must be set up using AVEVA Catalogue, it has been designed for the exclusive use of ISODRAFT, only a summary is presented here.

Bolt Tables (BLTAB) elements are an administrative element which are used to hold Bolt Length Tables (LTAB) elements, Bolt List (BLIS) elements and Multi Bolt List (MBLI) elements. LTAB elements store Standard Bolt Lengths for specific diameters (DTAB element). BLIS elements are used to group together standard bolt elements (SBOL) and MBLI elements are used to group together multiple bolt elements (MBOL).

• Length Table

• Single Bolt Table

• Multi Bolt Table

Bolt Table Utilities

Many multi-purpose windows provide similar functionality through the create and modify options, the functionality is common throughout all disciplines. Refer to Multi-Purpose Windows for further information.

The Bolt Table Utilities window is divided into three tabs, by default the Bolt Lengths tab is selected.

Length Table

Bolt Length Tables (LTAB) element are an administrative element, which store Standard Bolt Lengths for specific diameters (DTAB element). Use the Length Table part of the Bolt Table Utilities window to create or delete a LTAB element, the Bolt Name field is populated by default with the Unset.

Note: The Length Name cannot contain spaces.

A new LTAB element is created in the database hierarchy and displayed in the Catalogue Explorer, the element is also displayed in the list of Available Length Tables.

Further entries can be added to the list of Available Length Tables as required. If a Length Table is to be deleted, a Warning window is displayed:

A Diameter Table (DTAB) element contains all the available lengths of bolt for given diameter and material specification. Use the Diameter Table part of the Bolt Table Utilities window to create or delete a DTAB element. The Diameter Table Name field is populated by default with the Unset.

Note: The Diameter Table Name cannot contain spaces.

A new LTAB element is created in the database hierarchy and displayed in the Catalogue Explorer, the element is also displayed in the list of Available Length Tables.

A new DTAB element is created in the database hierarchy and displayed in the Catalogue Explorer, the element is also displayed in Diameter Table Name part of the Bolt Table Utilities window.

Populate the Create Length Values fields to create standard bolt lengths for specific diameters. When used in ISODRAFT, these diameter tables are used to round the bolt lengths up to the nearest standard length.

Single Bolt Table

Bolt List (BLIST) elements are administrative elements used to group together Standard Bolt Elements (SBOLT). Use the Single Bolting tab of the Bolt Table Utilities window to add or delete an administrative BLIST element. The Bolt Name field is populated by default with the Unset.

Note: The Single Bolt Name cannot contain spaces.

A new BLIST element is created in the database hierarchy and the entry is displayed in the Bolt Name pane. Further entries can be added to the Available Bolt List as required. If a bolt list is to be deleted, a Warning window is displayed:

Click Add Bolt to add the single bolt list to the bolt elements part of the Bolt Table Utilities window. With an entry highlighted, populate the Single Bolt List part of the Bolt Table Utilities window to set attributes values for the SBOLT element.

The caption above Single Bolt Elements states "Available Sbolt’s in ..". The caption changes depending on the selected entry in the list.

Number of bolts are used when calculating bolt length, extra length caters for extra threads beyond the end of the nuts and non std bolt length.

Additional attributes or Bolt Items can be added to the SBOL element, for example for washers, nuts and so on. To add additional attributes or bolt items, click Add Item to add a row to the Bolt Items list. By default, the Item Length is set to 0mm and the Item Name is Unset.

Multi Bolt Table

This functionality can now be now referred to as the Bolt Reference Array on a component, if the flange rating on each end of a Flange Component is different.

For example: a Pressure Relief Valve (PSV) or a Pressure Reducing Valve (PRV), the inlet may be 100NB 300# and the outlet 150NB 150# so the Bolts size, count and length would be different.

Multiple Bolt Lists (MBLI) are administrative elements used to group together Multiple Bolt Elements (MBOLT). Use the Multiple Bolting tab of the Bolt Table Utilities window to add or delete an administrative MBLI element. The Bolt Name field is populated by default with the Unset.

Note: The Bolt Name cannot contain spaces.

The functionality to add or delete an MBLI element is identical to that for an BLIST element.
