PSA5 – Pipe Stress Analysis Software
COMPUTING SYSTEMS
For the Petrochemical, Power, Offshore and Manufacturing Industries
OverviewPipe stress analysis and code compliance checking is acomplex and time consuming task. The PSA5 softwarepackage from Whessoe Computing Systems helps youcomplete such calculations more quickly andaccurately than ever. Running on a standard PC, PSA5can stress analyse the most complex piping systemssubjected to thermal, gravitational, wind, shock andseismic loads and produce stresses and compliancereports for a wide range of international design codes, including:
• ASME III Class 1, 2 and 3• ASME B31.1• ASME B31.3• ASME B31.4• EN 13480• BS806• BS7159
To ensure that PSA5 keeps pace with design codes andtechnological changes, Whessoe employs a dedicatedteam of software and piping engineers to provide firstclass support to users.
Whessoe has a 200 year history, a century ofexperience in designing and fabricating piping systemsfor the power and petrochemical industries, and withPSA5, a track record of 50 years as a de facto standard
with plant owners, contractors, piping fabricators,design consultants and engineeringinsurance/inspection authorities.
Technical FeaturesPSA5 has a straightforward user-friendly interface forcreating and editing piping models. Standard and user-extendable libraries are provided containing propertiesfor a wide range of materials and fittings. You needonly specify information such as nominal pipe size,schedule, material and temperature - which are thenassigned automatically as pipe routes are defined.
The model is displayed in centre-line or 3D mode andcan be modified on a global or local basis throughoutthe design cycle. Supports, anchors, point loads andapplied deflections can be entered at any time andextensive use is made of colour-coding for ease ofinterpretation. Powerful viewing and editing facilitiesmake entering complex models simple.
PSA5 can carry out static analysis of the piping modelssubject to various categories of load including: selfweight, live weight, thermal expansion, imposeddeflection, wind, pseudo-static loads and internalpressure. The forces and moments exerted on allexternal attachments are calculated, together withforces, moments, deflections and rotations throughoutthe model.
Whessoe Computing Systems – PSA5
Full dynamic analysis can also be performed,evaluating the response of the model to loads thatvary rapidly with time, such as pressure surges andearthquakes. PSA5 can perform uniform supportmotion, independent support motion and force timehistory analysis.
Reporting and results checking - PSA5 provides acomprehensive graphical results interrogation facilitythat uses the pipework display as an index into theanalysis results. This allows you to quickly investigatepoints of interest and produce reports in variousformats. External reactions at supports and equipment can be conveniently passed to civil andstructural disciplines.
Additional analysis capabilities include automaticsupport selection, thermal transient analysis androtating machinery compliance analysis to NEMA Sm23,API617 and API610.
Quality AssuranceThe assurance of both quality and accuracy are veryimportant to Whessoe Computing Systems. PSA5 hasbeen fully validated by comparing the answersobtained with hand calculations, other software,published results, analytical solutions and previouslyvalidated releases.
Whessoe Computing Systems operates a QA programmedesigned to meet the requirements of ISO9001 and theASME Boiler and Pressure Vessel Code Section III. Thisquality system has been subject to third party audit byaccredited certification bodies and WhessoeComputing Systems has been registered as acertificated organisation.
