Piping and Equipment Analysis for Food and Drug Processing Operations

Food and Drug processing operations are becoming more sophisticated making it more challenging to include the appropriate engineering of necessary piping systems and equipment with a wide array of different technological, mechanical, and safety requirements to comply with. PSRE (Piping System Research & Engineering Co.) offers a complete solution for engineering of Piping Systems and related equipment including engineering consulting and the PASS Software Suite.  The PASS/INDUSTRY Process Complete module of the PASS Software Suite provides a comprehensive solution for Process Plant design and analysis with powerful and easy to use software tools of analysis, simulation, code compliant sizing that include embedded intelligence and integration with popular CAD tools.

The PASS Software Suite offers smart, easy-to-use analysis, simulation, and code compliant sizing tools for every piping and equipment engineer/designer enabling new users to perform piping and related equipment analysis in days rather than months.  By embedding its experience from many engineering projects into the PASS software tools and combining this embedded intelligence with powerful capabilities and unsurpassed usability, PSRE makes piping and equipment analysis practical for every engineer and designer while reducing the time, effort, and cost to perform the analysis.


PASS Software Suite Overview

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

The PASS Software Suite 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

The PASS Software Suite 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.  The PASS Software Suite has proven its usefulness by helping more than 2000 customers around the globe to successfully and efficiently design complex piping systems and related equipment.


PASS Software Suite Application Families

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

PASS/INDUSTRY provides comprehensive piping and equipment analysis with related sizing calculations for specific industry sectors according to international and national codes and standards. PASS/INDUSTRY combines the ease of use and extensive analysis capabilities of PASS/START-PROF, PASS/HYDROSYSTEM, and PASS/EQUIP in an organized manner to address the specific simulation requirements for Process Plants, Piping systems, and District Heating.

Extensive analysis capabilities, along with integration with popular CAD tools and within the PASS suite, makes PASS/INDUSTRY an ideal component for any design workflow.

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.

First introduced in 1965, PASS/START-PROF combines a highly efficient solver, powerful analysis features, a user friendly GUI, an intuitive 3D graphical pre/post-processor, and a detailed help system with embedded intelligence from generations of piping design experts.

PASS/START-PROF offers many functions that make piping model creation very quick including: group editing, quick loop addition, node point renumbering, and spring data application. PASS/START-PROF can import piping models ready for analysis from AVEVA PDMS and E3D, Caesar II, and PCF formats. Data can also be exchanged within the PASS suite and with a large spectrum of general and special purpose CAD and CAE software tools.

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/EQUIP provides the ultimate in usability by “regular” engineers allowing them to focus on the equipment design. The user defines the equipment type, geometrical adjectives, material of the vessel components, type and allocation of supports, test type, and loading rates. Selection of vessel elements and materials is made from the vast databases, which can be updated by the user.

3D graphic display of equipment geometry is provided with the possibility of editing the color of separate elements or the whole model, with views to make it possible to see internal elements. Powerful 3D modeling opportunities also support export to various CAD formats, so the user could continue work on vessel design in his favorite CAD environment.

PASS/HYDROSYSTEM provides diameter selection, heat and hydraulic analysis of steady state and transient flow in piping systems of any complexity, including networks with loops. It also covers the most dangerous type of transitional flow related to liquid surge (water-hammer), multiphase flow analysis (including settling slurries flow), and flow assurance calculations (including severe slugging and gas hydrate formation prediction), and calculates unbalanced forces for piping stress analysis.

PASS/HYDROSYSTEM provides a calculation engine for all necessary fluid properties and phase equilibrium on the base of fluid composition, for a wide spectrum of fluids and applications.

PASS/HYDROSYSTEM also uses the most advanced models/algorithms and libraries for all levels of simulation (both proprietary and from the most famous researchers/ developers from all over the world).
