Intergraph PV Elite is a complete solution for vessel and heat exchanger design, analysis and evaluation. Users of PV Elite have designed equipment for the most extreme uses and have done so quickly, accurately and profitably.

Intergraph PV Elite is a comprehensive program for the complete structural design or analysis of tall towers and horizontal vessels according to latest standards from ASME, PD 5500 (British Code), UBC, EN-13445, API-579 and the Welding Research Council.

PV Elite evaluates the entire vessel, analyzing the effects of vessel deadweight and bending due to wind and seismic loads. It combines these overall loads with pressure to design and/or check vessel wall thickness. Basing stress calculations on this total structural load ensures sufficient wall thickness for the vessel in its operating environment and ensures proper design of the vessel supports.

Element types include cylindrical shells; elliptical, spherical, torispherical, conical and flat heads; conical sections (including knuckles); body flanges; and skirts with base ring details. The program provides base ring, saddle, leg and lug design and also includes modules for analyzing vessel components such as nozzles, flanges, base ring and other vessel components.

To make the design process easy, the status bar constantly displays the position of the current element, its required thickness, its maximum allowable working pressure and its maximum allowable pressure in the new and cold condition. Graphic presentation keeps your data organized and confirms the integrity of the model.


Data Collection

PV Elite makes defining pressure boundary conditions for vessels and exchangers easy, even for load sets that require significant data input. PV Elite streamlines data entry by breaking the input down into sensible subsets. Help on any input item is only a keystroke away.


PV Elite's graphical representation of analysis models helps ensure confidence in the input and results. With PV Elite, analysis models can be viewed and manipulated with complete ease.

Analysis Options

PV Elite performs calculations in accordance with ASME Section VIII Divisions 1 & 2, PD 5500 and EN 13445. Rules from API579 (Fitness for Service) are also included for evaluating the current state and remaining life of existing vessels.

Outputs and Reports

To simplify inspection requirements, PV Elite lists the most important equations such as required thickness and maximum allowable working pressure (MAWP) and also groups results by type (e.g. internal pressure, external pressure, bending stress, nozzles and flanges). Overall results are summarized where the element or detail controlling the overall vessel MAWP is identified.

Materials and Codes

PV Elite is a global package with international code rules plus extensive region-specific content. Vessel material definitions, piping and steel component data, local wind loads and local seismic loads of many regional markets are all included.


PV Elite interfaces with other popular software packages for finite element analysis, foundation design and drafting. PV Elite also shares a bi-directional link to Intergraph CADWorx® Equipment module and Intergraph PV Fabricator™.


Building complex vessel models in PVElite is quick and easy. As each major element is added, the graphical display is updated to show the new element in relation to the others. This image confirms the content of the model. Clicking on the element in the plot brings up the tabular data for that element. As details (such as nozzles, insulation or trays) are added they too are illustrated, and clicking on them will bring up their data for review. Click on the image below to see the input in PVElite.

PV-Elite designs to ASME Section VIII, Division 1, Division 2, EN-13445 & PD-5500.

Other geometries can also be confirmed graphically, namely basering layout and nozzle-shell junction. PVElite has an interactive 3D viewer that lets you review your model in great graphical detail.

PVElite has following basic elements:
  • Cylindrical Shells
  • Elliptical, Spherical, Torispherical, Conical and Flat heads
  • Conical Sections (including knuckles)
  • Body Flanges
  • Skirts with Basering details

following details can be attached on the basic elements:

  • Stiffening Rings
  • Nozzles
  • Dead weight and applied loads
  • Platform (both circular and rectangular) and Ladder
  • Trays and Packing
  • Saddles, Legs and Lugs
  • Fluid
  • Insulation and Lining

With a simply click on an icon, the component is added to the vessel. This provides a logical and intuitive modeling of the vessel. Other operation features include toolbars that can be positioned any way on the screen for optimum usability and a status bar that constantly displays an element's required thickness (due to pressure), vertical height, maximum allowable working pressure in operating condition (MAWP) and maximum allowable working pressure in new and cold condition (MAPnc). This insures that you are always aware of how changes to a design are affecting the vessel. You can also instruct the program to automatically set the thickness of each element to the minimum required thickness, while inputting the vessel.

PVElite includes complete material property databases, for ASME Sec. VIII, Div. 1 and Div. 2, EN-13445 and PD5500 (British code). Hence the user can easily select any code material and can also create a new one.

Features like automatic carrying forward the relevant data for newly added elements, copying input from one detail to another and 1-click sharing of data among elements aid in faster modeling.

PVElite allows users to enter data in English, SI or any user-defined units. Using the Create/Review facility users can create their own units and then change units on fly. The unique List Processor provides a concise method to review specific data sets, for example all the nozzles in the model. The fields in the List Processor tables are active, allowing user modification of the data.

The "help" facility provided with PVElite gives the user access to very specific information about the current input cell or menu selection. The help facility, details exactly what is expected, sometimes shows explanatory diagrams, and when appropriate, cites the code reference.

The program documentation is available on-line in a portable document format (PDF). Acrobat Reader software needed for viewing the on-line documentation can be installed from the PVElite CD.
