Smart Simulation & Sizing Tools for Every Piping and Equipment Engineer/Designer

PASS Application Families

The PASS software is organized into product families to meet the broad range of piping systems analysis and design requirements.

PASS/HYDROSYSTEM for piping hydraulic and thermal analysis & sizing.
PASS/START-PROF for piping stress analysis & sizing.
PASS/EQUIP for equipment analysis (vessels, columns, heat exchangers, tanks, nozzles).
PASS/INDUSTRY for industry specific piping and equipment analysis.

PASS/START-PROF provides comprehensive pipe stress, flexibility, stability, and fatigue strength analysis with related sizing calculations according to international and national codes and standards.

PASS/EQUIP provides strength and stability analysis for horizontal and vertical vessels, columns, storage tanks, as well as shell, tube, and air-cooled heat exchangers under static and seismic loads in order to evaluate bearing strength. PASS/EQUIP also provides finite element analysis of vessel nozzles for the purpose of estimating their stress, stiffness, and allowable loads.

PASS/INDUSTRY provides piping and equipment simulation and sizing based on industry specific bundles of PASS modules.

PASS/INDUSTRY is currently arranged in different configurations to meet the specific needs for Process plants, Piping systems, and District Heating.

PASS Overview

Pipelines are everywhere serving many purposes including: supplying water and natural gas, transporting wastewater, providing heat, transporting oil and gas, circulating steam/water at power stations, linking equipment in process plants, transporting of propellant and oxidant into jet engines, circulating fluids and exhaust for an automobile, and more. The engineering of a piping system is a challenging task with a wide array of different technological, mechanical, and safety requirements to comply with. It is simply impossible to effectively design complex modern piping systems without powerful and easy to use software tools of analysis, simulation, and code compliant sizing.

The PASS software tools combine embedded intelligence with powerful capabilities to make piping and equipment analysis practical for every engineer and designer while reducing the time, effort, and cost to perform the analysis. The result is smart simulation and sizing tools for every piping and equipment engineer/designer that enable new users to perform piping/equipment analysis in days rather than months.

Piping simulation requires highly specialized CAE software that incorporates knowledge of piping behavior delivered efficiently to any process and piping engineer or designer in an easy to use form for every day work.

PASS covers all main aspects of pipeline analysis including:

  • Piping systems stress, fatigue, and stability analysis & sizing
  • Equipment stress analysis for vessels, columns, tanks, and heat exchangers
  • Nozzle-Shell Junction stress and flexibility analysis
  • Piping systems fluid flow and thermal analysis & sizing
  • Industrial thermal insulation calculation
  • Pressure relief system sizing

PASS is already in active use by thousands of engineers for analysis and design of process piping and plant utilities, district heat transfer, water and gas networks, oil and gas field gathering piping systems, and other types of pipelines.
