No. Each COMPRESS release contains all previously
available Code Editions and Addenda as well as the
year's "new" Edition or Addenda. For
example, if you have COMPRESS build 6255 (or later)
you can specify the 2007 Edition of ASME Code as
well as any Edition or Addenda from 1995 through
A06. Multiple COMPRESS installations are not
required to produce calculations to different Code
Addenda. This powerful feature allows COMPRESS
users to easily work on "new" vessels and
exchangers as well as on re-rates or modifications
to existing equipment without switching programs.
The ASME Code Addenda is selected in COMPRESS in
only one location. Changing a single setting
directs COMPRESS to use the corresponding ASME
Section VIII Code rules and Section II, Part D
material properties.
In COMPRESS, the Code Edition/Addenda that a vessel
is designed to is a property of the "CW6"
design file. You design a vessel to a particular
Edition/Addenda and save it. That Edition/Addenda
will always be used for that vessel when the file
is opened in any later COMPRESS update. You can
specify the Edition/Addenda for each file as
desired. There is also a default setting for new
files. This is set to the latest Code
Edition/Addenda at Codeware but users can specify
an earlier Edition/Addenda as the default to be
used for new files if desired.
The ASME Code Edition or Addenda for any COMPRESS
file is set from the Codes\ASME
menu option. From the
ASME Codes dialog (see
below) select the desired Edition/Addenda, and any
other Code options; then click "OK".
Changing the ASME Code here causes both the Code
rules (from Section VIII) and allowable stresses
(from Section II) for that Edition or Addenda to
be applied to the current vessel or exchanger. No
other changes are required and no additional user
input is needed when changing ASME Code Addenda
for any COMPRESS file.
A quick method of changing the ASME Code selection
for an existing file is to "right-click"
the current Code selection on the Status Bar at
the lower right corner of the COMPRESS window and
select the desired Code; see below:
Some files, namely those created using an expired
COMPRESS key, may not be eligible to be updated to
the latest Edition of ASME Code. Such files would
be restricted by the rules presented in this
document:
