Released 24-Mar-2023

Release Notes

Piping Design


The B31.1 2022 design code has been added.



A new Slide Component operation has been added which allows clicking and dragging an existing component along pipelines to a new location. The moved component’s assignments remain, and pipeline repair occurs as needed.

User Interface


The text file report created when a CSiPlant model is exported has been enhanced to include more detailed information for each model element, as well as adding design properties, pressure and temperature loads, and components such as valves, flanges and reducers.

Bug Fixes


Issues reported by users have been corrected.


Released 8-Sep-2022

Release Notes

Piping Design


B31.8 – 2020 Design Code has been added, which includes an updated Tresca criterion when calculating combined stress for offshore piping.


Design with codes B31.8-2016 and B31.8-2016 2018 now performs a stress calculation to determine the contribution of pressure to the longitudinal stress.



GB 50251 – 2015 Design code has been added. This design code implementation includes restrained and unrestrained piping and the Appendix C method for considering circumferential stress in elbows.


Individual design requests can apply multiplicative friction factors on all supports with Gap behavior, which can be used to study sensitivity to the friction properties.

Import and Export


The ability to export a text file representing all CSiPlant model data has been added with multiple formatting options.

User Interface


Responsiveness of the user interface has been improved for models with distributed supports with small stiffness factors which requires significant auto-meshing of members.

Bug Fixes


Issues reported by users have been corrected.

7.0.0 | 7.1.0

Released 7-Mar-2022

Release Notes

Piping Design


Piping design has been implemented for the following ASME codes:
  1. B31.1-2020
  2. B31.3-2020
  3. B31.4-2019

Structural Model


Expansion joints in pipelines can now be modeled. Types include single, hinge, and gimbal.


Distributed soil supports can now be modeled along pipes that follow the recommendations by American Lifelines Alliance.



Pulsation loads due to reciprocating pumps and compressors can now imported from BOSpulse as a time history load case.



Speed improvements have been made for nonlinear analyses that involve a large number of load patterns.



The time to create animations has been significantly decreased.


Model objects can now be displayed by color based on object type, section property, material, pipe property set, pipeline, and group.



A new command has been added to rotate model objects about any axis.


Valves assigned with concentric and eccentric component weights are now distinguished graphically.


Replicate and mirror commands now include the option to select points on the model for determining the offset distance.

Output and Display


Custom filters are now available for non-numeric columns in the display tables.
