Result
When you calculate a flanged pipe part in the engineering data, the following happens:
●
The matching bolt set in the pipe spec is determined.
● The bolt set is calculated.
● The bolt set is created below one of the bolted parts or below the bolt set group.
– The placement location of the bolt on the isometry is assigned to the bill of materials via
the item number.
– A unique key is generated for each bolt set. The item number of the gasket is at the first
position, followed by item numbers of the other components. The item numbers are
listed in ascending order.
– If a component is placed on two isometries, the "#" character is used for the connected
component if it does not have an item number.
Viewing the properties of the calculated bolt set
You can find out more about the result of the calculation in the properties of the bolt set on the
"Attributes > For bolt calculation" tab.
The following information will be displayed:
● "Bolting definition" control group
– The control group contains information on the bolt and the associated parts, such as
the nut and washer.
– The number of bolts used and the calculated length of the bolts is shown. See also
chapter Algorithm for calculating the screw length (Page 146).
● "Used bolt parts" control group
The control group shows which bolt parts are used with which properties in the engineering
data.

8.12.7 Using bolt set groups
You can use bolt set groups to manage bolt sets via the pipe spec.
Bolt set groups have the following advantages:
● All bolt sets of a connection are sorted below the bolt set group.
● If you dissolve the connection of two pipe parts, the group and all associated bolt sets are
automatically deleted.
● The bolted connection is visible in the Navigator even before the calculation.
