Rules for different bolt sets
Joint Rule
Flange - flange Both bolt sets must be identical.
The bolt set found first is used.
Flange - valve - flange The bolt set of the valve is used.
Contiguous flange group with
clamp part
The bolt set of the clamp part is used.
Bolts calculation
The data required to calculate the bolted connections is taken from the following sources:
●
The geometry standards for the flanges
● The geometry standards for the bolt parts
The type of bolted connection set at the flange pipe part determines which algorithm COMOS
uses to calculate the bolt lengths.

3.8.2 Creating a bolt set
Requirement
● Observing the workflow for preparations that must be made for creating and managing pipe
specs. See also chapter Basic procedure for preparation (Page 15).
For creating bolt sets this means:
– The standard tables required for bolt parts are complete.
See also chapter Standard tables for bolt parts and bolt sets (Page 66).
– The important geometry standards for bolt parts, flanges, and gaskets are included in
the "standard geometry tables" standard catalog.
See also chapter Managing the "standard geometry tables" standard catalog (Page 19).
– The pipe part catalog contains bolt parts, flanges, and gaskets.
See also chapter Administering pipe part catalogs (Page 27).
● You have selected the "Base objects" tab in the Navigator.
Procedure
1. In the Navigator, open the node under which the bolt sets are located.
"@50 > A10 > A10 > A20 > Bolt sets"
2. Select the node of the required system of standards.
