3.8 Preparing bolt sets
3.8.1 Fundamentals of bolt sets
Bolt sets are base objects with assigned bolt parts. They determine the quantity of components
related to a bolt hole.
When you use a flanged pipe part in the engineering data, COMOS determines the appropriate
bolt set and calculates the bolts. Bolt sets are created below the pipe section. One bolt set is
created for each flange plate and counterpart flange plate. You will find detailed information
on the components of the bolt set in the properties of the bolt set.
A bolt set always refers to the drilling pattern of a flange plate. It defines a specific number of
bolts with certain dimensions, depending on the pressure stage and standard. Bolt sets can
contain different types of bolted connections. Example: For smooth holes or holes with thread
Selecting the right bolt set in the engineering data
Whether or not the flanged pipe part has been specifically assigned to a bolt set determines
which bolt set is used in the engineering data:
No bolt set assigned (standard procedure):
● The pipe spec and nominal diameter of the pipe part are determined.
● COMOS checks which bolt sets are available in the pipe spec for the nominal diameter:
– With a matching bolt set: The bolt set is used.
– With several matching bolt sets: COMOS uses the bolt set that was set as the
preselected component for the nominal diameter.
See also chapter Using bolt sets in pipe specs (Page 110).
Bolt set assigned:
● If a bolt set has been assigned to the pipe part in the pipe part catalog or at the pipe spec
element, COMOS uses the assigned bolt set.
