1 Use a section header for each of the topics, so there is a clear transition to the audience.

2 Design of pressure vessels using PV Elite
  Petroleum University of Technology Abadan Faculty of Petroleum Engineering Design of pressure vessels using PV Elite By: Aslan Momeni This template can be used as a starter file for presenting training materials in a group setting. Sections Right-click on a slide to add sections. Sections can help to organize your slides or facilitate collaboration between multiple authors. Notes Use the Notes section for delivery notes or to provide additional details for the audience. View these notes in Presentation View during your presentation. Keep in mind the font size (important for accessibility, visibility, videotaping, and online production) Coordinated colors Pay particular attention to the graphs, charts, and text boxes. Consider that attendees will print in black and white or grayscale. Run a test print to make sure your colors work when printed in pure black and white and grayscale. Graphics, tables, and graphs Keep it simple: If possible, use consistent, non-distracting styles and colors. Label all graphs and tables. Spring 2014 Abadan-Iran

3 Principles of pressure vessels

4 Definition as related to Standard:
EN 13445: A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. And other standards such as ASME section VIII and etc. The PVElite software can design pressure vessels base on ASME , PD5500 , EN13445. Shape of the pressure vessels. That is divided in two major groups: Cylindrical pressure vessel. Spherical pressure vessel. Give a brief overview of the presentation. Describe the major focus of the presentation and why it is important. Introduce each of the major topics. To provide a road map for the audience, you can repeat this Overview slide throughout the presentation, highlighting the particular topic you will discuss next.

5 Cylindrical Spherical

6 Formation components of pressure vessel:
Shell Saddle Lifting lug Leg lug Skirt

7 The information of the pressure vessel that designed by process engineering group classify in Design Data Sheet(DDS).

8 Basic part of the pressure vessels.
This is another option for an Overview slides using transitions.

9 Shell: That is the basic part of the pressure vessels and mainly manufactured by rolling of the flat sheets.

10 Head section:

11 Various type of the head section:

12 Flange: Nozzles: Are used for leading the follow in or out , install equipment , ventilation and etc.

13 Various type of the nozzle:
Set-through Set-in Set-on

14 Various type of the support:
Skirt that are used for vertical pressure vessel. Saddle that are used for horizontal pressure vessel. Leg support Lug support

15 The information that we should know!

16 Pressure: Absolute pressure Gauge pressure
Atmospheric pressure( Mpa) Operation pressure Design pressure Maximum allowable working pressure Maximum allowable pressure , new and cold Hydrostatic test pressure

17 Temperature: Operation temperature Design temperature(UG-20)
Minimum design metal temperature

18 Allowable tensile stress:
Loading: Loading that caused from internal and external pressure The weight of vessel and contents The weight pump , duct , pipe and etc Loading that caused from earth quake , wind and etc Allowable tensile stress: ASME Appendix sectionII part D Allowable compressive stress: ASME Appendix sectionII part D

19 (just for shell of the pressure vessel)
Some calculations (just for shell of the pressure vessel)

20 Hoop stress(P≠ 0.385SE , t≥0.5R ):
P=internal pressure(psi) S=maximum allowable stress(psi) sectionII , part D R=internal radius(in) t=minimum require thickness of shell(in) E=joint efficiency UW-12

21 Longitudinal stress(P≤1.25SE , R≤0.5t ):
Spherical shells(t≤0.365R , P≤0.665SE ): corrosion situation: Rnew = Rold + corrosion allowance.

22 Post Weld Heat Treatment(PWHT) and Preheat:
Are needed when the thickness are more than inch. Radiographic(base on table UW-12 for P.No and Group No): Otherwise , spot radiography is adequate!
