PASS/HYDROSYSTEM software performs flow rate, pressure drop, surge and heat loss calculations, and nominal size selection for process and power piping, heating, gas-distributing, and other pipe networks with gas, liquid or multiphase flow. Fluid properties and phase equilibrium can be calculated based on fluid composition using embedded thermodynamic libraries or Simulis Thermodynamics from ProSim.

PASS/START-PROF software evaluates stress for process and power piping, gas, and oil transmission, and heat networks. Stress and fatigue strength analysis is performed for pipe elements including buried pipelines according to different standards. Pipelines with various types of restraints and expansion joints under static, cyclic, and seismic loading are evaluated. The software can automatically select spring supports and their properties.

PASS/EQUIP software allows strength and stability analyses for horizontal and vertical vessels, column apparatuses, storage tanks, shell and tube, and air-cooled heat exchangers under static and seismic loads in order to evaluate bearing strength in operation, test and assembly states.

PASS/EQUIP Nozzle-FEM software performs finite element analysis of vessel nozzles for the purpose of estimating their stress, stiffness and allowable loads. A finite element mesh is generated automatically for arbitrary shell, head, and nozzle dimensions. Calculated nozzle flexibility can be automatically used in START software.

Additional PASS software modules provide pressure relief system analysis (PASS/RELIEF), piping and equipment insulation design (PASS/INSULATION).


  • PASS is based on the firm foundation of universally accepted engineering calculation methods, and on ISO, EN, ASME, API, WRC, Russian GOSTs, Chinese and other standards. It also uses the most modern achievements in engineering analysis and scientific research.
  • User friendly 3D graphical interface, detailed help and manuals, and interactive training movies make working with PASS products easy and pleasant for both beginners and professionals.

  • The calculation results are shown on the graphical model and can be outputted as MS Word, PDF, HTML, MS Excel files and other formats. Output templates can be edited by the user.
  • PASS interoperability is always our priority. We provide integration of various PASS components, as well as data import and export to various CAD software, including AutoCAD and AutoCAD Plant3D.
  • PASS has been continuously improved for over 30 years.


The annual support plan provides 12 months of automatically downloaded updates and phone and email technical assistance. Training by our certified specialists can be provided at your location or in our training centers for an additional fee.
