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 is so smart that you need just draw the piping like in 3D modeling software and push the button "run analysis". PASS/START-PROF user should think about piping design, not about node numbering, model creation, etc. PASS/START-PROF will tell you if your model has any problems and show where exactly. All checks are made automatically: stresses, support loads, expansion joint deformations, flange leakage, buckling, loads on springs in all operating modes, stresses in insulation, and stresses in flaws. Table cells with a problem are marked with a red color. All results can be presented in any coordinate system: global, local. PASS/START-PROF offers detailed pipe stress report with all equations that was used; you can check all equations manually.

In PASS/START-PROF everything is simple and straightforward, since you are working with modern object model. You can compose your piping using objects like pipe, bend, tee, reducer, cap, expansion joint, restraint, valve, flange, and other like in 3D modeling software. You don't have to bother with node numbering at all; you can modify your model at any moment using copying, rotating, mirroring, node renumbering, cut, copy, paste any part of the model, add nodes, delete nodes.
PASS/START-PROF can import piping models ready for analysis from CADWorx, SmartPlant 3D, AVEVA PDMS, AVEVA E3D, Autodesk REVIT, Bentley Autopipe, HEXAGON CAESAR II, OpenPlant, Autoplant, Smart 3D, etc. You can modify your model without any problem after import.
PASS/START-PROF offers quick 1st hand support from developers and from experienced piping engineers in UK, China, Mexico, Brazil, Australia, Egypt, Turkey and other countries. Support response speed and quality is guaranteed and can be offered on regional language. User feedback is accepted and used to improve development of PASS/START-PROF.
PASS/START-PROF and PASS/NOZZLE-FEM is free integration module that allows to use the finite element method analysis with shell elements to calculate the stress intensification factor (SIF) and flexibility k-factors, allowable loads on nozzles and analyze stresses in critical elements using FEA. Using this module allows to overcome the application limits of code and calculate the SIF, k, and allowable loads more accurately and less conservative which save the metal volume and reduce the piping cost.
The Smart Operation Mode Editor allows users to just draw the piping, add general snow, wind, ice, as well as seismic load information and run the analysis. All appropriate load values and load cases will be created automatically according to selected codes. Time consuming manual creation of load cases is no longer needed. Smart Operation Mode Editor allow you to analyze several operation modes of piping in one project file. For each operation mode the special template load cases automatically generated.
Pipelines that can be analyzed include piping for: process and power, gas and oil transportation, district heating piping, hot water supply, and more. Stress, flexibility, stability, and fatigue strength analysis are performed for buried, above ground, vacuum, high pressure, high temperature, and cryogenic piping. Pipelines with various types of restraints, fittings, and expansion joints can be easily evaluated. PASS/STARTPROF also offers automatic selection of constant and variable spring supports.
PASS/START-PROF can model soil flexibility + PUR insulation layer flexibility + expansion cushion flexibility including soil settlement and swelling modeling, longitudinal stability analysis, buoyancy and flooded soil. The user can simply specify soil type from database, and define the pipe depth to run the analysis without having to specify restrained and unrestrained zones, calculate the virtual anchor length, nor run a soil modeler. PASS/START-PROF will automatically do what is required for the correct soil simulation. PSRE has several years of experience modeling buried piping for District Heating and other applications.
Easy to use plastic piping analysis for polyethylene (PE), polypropylene (PP), polybutene (PB), Polyvinylidene fluoride (PVDF), polyvinylchloride (PVC) etc. according to DVS 2205/DVS 2210 is provided. Above-ground and buried plastic piping can be analyzed, including PUR insulation layer.
PASS/START-PROF include following databases: Materials Contains the physical properties of pipe and fitting materials. Each piping code has own database section. Due to this, plastic piping, fiberglass (FRP, GRP) piping can be calculated as easy as steel piping. You just select preferred material from database.
PASS/START-PROF has a smart, easy and friendly user interface with user manuals in English, Chinese, and Russian languages. Fast piping modeling allows even the beginner without any special training to be able to perform pipe stress analysis.
PASS/START-PROF can be delivered in different configurations to evaluate the piping stresses, displacements, and support loads from thermal expansion, cold-spring, soil and support subsidence, and other loads according to applicable standards and codes.
Engineering activities mainly focus on industrial plant design, with the development of all project stages, including piping, structural metalworks, electronic instrument systems and mechanical engineering. 2ff7e9595c
