Pressure Vessel Code Updates

PD 5500:

� This code was originally published in 1976 as BS 5500� The main formulae for the pressure envelope have remained static� Enhancements have been introduced over the years� Is used as the basis (for some of the features) for EN 13445 Part 3� It very nearly complies with the PED (Pressure Equipment Directive)

PD 5500 Changes in PV Elite 2013

� Updated to the 2012 edition of PD 5500

For example:

� Minor change to the flat head calculation� for Category 3 – used Category 1/2 allowable stresses

3/26/2013 4


TEMA (Tubular Exchange Manufacturer’s Association):

� Updated to the 9th Edition (2007)

Changes in the 9th edition:

� The tubesheet calculation remains virtually the same� The analysis of expansions joints has been removed

� The previous method was too conservative� TEMA recommends FEA be used instead� However PV Elite has the previous analysis� An FEA programme is available from Paulin Research Group

Reminder:

� Cannot use TEMA for ASME Coded vessels !

API Fitness for Service

� This is completely new in PV Elite� At the moment we have encorporated the 2007 edition

� Limited to Levels 1 and 2, but we are working on it

3/26/2013 6


Really new: We have started enhancing PV Elite with languages

� English – formerly the only available language� Spanish� Italian� Portuguese� French

This is an example of the French Language

� There is also an updated AS/NZ 2011 Wind Code

Lifting lugs

Tubesheets

Jackets

3/26/2013 10


Take a closer look at Jackets

We can have a jacket on a vessel like this:

There may be a hole or holes in the shell for a vapour belt

This is fairly common in heat exchanger design

3/26/2013

You have now imported the data into you current model

3/26/2013 28

Useful Enhancements

In the Output Processor, you can easily select all the reports

Select all the text in a report

Or select all the reports in the list

3/26/2013

15

3/26/2013 29

Useful Enhancements

In the output processor click on the Print icon

Then select: PV Elite PDF Printer

Then click on the OK button

We now have the ability to send the report direct to PDF

3/26/2013 30

Useful Enhancements

We can look at all the new features in PV Elite 2013

Click on Help��What’s New to get this screen

Scroll down and look at all the new features

3/26/2013

16

3/26/2013 31

Useful Enhancements

For example, look at the really new feature – Materials back to 1943

Go to Tools��Configuration to access the materials

To get the Data Base of earlier materials

3/26/2013 32

Useful Enhancements

Now you can compute the MDMT for Stainless Steels

This is a stainless steel

Stainless steel can operate at very low Cryogenic Temperatures

They are very resistant to brittle fracture

We look at another very useful feature

3/26/2013

17

3/26/2013 33

Useful Enhancements

Most Stainless Steels have Two allowable stress values

This is because of Note G5

In the case of Flanges – large deformations cannot be tolerated

3/26/2013 34

Useful Enhancements

Most Stainless Steels have Two allowable stress values

Must identify the high deformation steels when searching the materials

When selecting a material we can use this Button to do so

Those materials are then highlighted

3/26/2013

18

3/26/2013 35

Useful Enhancements

The Fatigue Analysis has also been updated to ASME Div 21010A11

This on the Nozzle Dialogue Screen

ASME VIII Division 2 uses formulae instead of a graph

3/26/2013 36

Useful Enhancements

For the European EN 13445 code, nozzle external loads

And from the drop down list box

This method is very different from the WRC 107 method

3/26/2013

19

3/26/2013 37

Useful Enhancements

3D Model, the axis of rotation can be locked in one position

3/26/2013 38

Validation of PV Elite

ASME has produced a book of sample calculations ASME PTB-3

We have used that book to benchmark PV Elite where we can

We used a different programme such as MathCad as alternative software

Here is a sample page from that book

3/26/2013

20

3/26/2013 39



3/26/2013 40



Here is the check calculation done in MathCad

Note: The check is done in both Imperial and Metric units

Many checks have been done in this way

3/26/2013

21

3/26/2013 41

We now look at CodeCalc

First, we look at how it used to look

This is the new look with the Ribbon

All the same icons are there, but are set out differently

The user interface has been radically changed

3/26/2013 42


The old Shell/Heads user inter face used to look like this:

Now it looks like this:

3/26/2013

22

3/26/2013 43


There are four tabs at the bottom of the screen that are useful

3/26/2013 44



3/26/2013

23

3/26/2013 45



3/26/2013 46



3/26/2013

24

3/26/2013 47



It is so quick when clicking from tab to tab

Look at the left side of the screen

3/26/2013 48



As you add component, a ‘Tree’ is built up

3/26/2013

25

3/26/2013 49



If you want to delete an item – just click on it in the ‘Tree’

Then click Delete

It is removed from the Tree

3/26/2013 50


Getting Output (the calculations ) is made easier

Need only click the <F12> key to get the output processor

You can get the output processor from the previous run

Do not need these buttons as you have the tabs

We have not shown all the features, but you get the idea

Remember, CodeCalc only does ASME VIII, Division 1

3/26/2013 51

The Advantages of using PV Elite

They are considerable:

� You can analyse a vessel with any of four codes� ASME Section VIII, Division 1� ASME Section VIII, Division 2� PD 5500 – The British code� EN 13445 – European code

� Includes the European PED� You can build the whole vessel with every component� It easier than CodeCalc building a heat exchanger� You have a choice of numerous wind codes� You have a choice of numerous seismic codes� You can see a scale model on your screen� You can use PV Elite building only one component

There is another big advantage using PV Elite over other software

3/26/2013 52

The Advantages of using PV Elite

Using Code Case 2695 for Division 1 vessels

This code case enable you to use Division 2 technology to design Division 1 vessels - Can still be U-1 stamped

There are two areas where this is advantageous:

� Can design thinner heads� Ellipsoidal heads� Torispherical heads

� Nozzle design� May be able to use thinner re-pads� May need less nozzle reinforcement

� The fabricator can bid on a lighter cheaper vessel� Less welding (thinner plate)� Cheaper to transport

This code case is worth looking at

The Evolution of ASME VIII, Division 1

The steamship Sultana exploded returning soldiers from the war

Most of the soldiers were killed on that voyage up the Mississippi

Tragedies were not rare

3/26/2013 54


This is the Brocket Massachusetts Shoe factory about 1905

3/26/2013

28

3/26/2013 55


And this is the site after the boiler exploded

Again there was huge loss of life

Amazing, the stack is still standing

3/26/2013 56


Here is yet another boiler explosion

This occurred in Hampshire England

The problem had to be solved – loss of life could not be tolerated

3/26/2013

29

3/26/2013 57


Early 1900’s American Society of Mechanical Engineers was approached

In 1915 they produced ASME Section 1 – Power boiler code

It had precise Rules for the design of boilers

In 1925 they produced ASME Section VIII – Pressure vessel code

Again – the key was: Rules for the design of Pressure Vessels

In 1968 they divided Section VIII into two codes

� VIII Division 1 – still containing the Rules� VIII Division 2:

� Allowing for design by Rule, or,� Design by stress analysis

In 2007 Division 2 was completely re-written from scratch

� Section 4 – Design by rule� Section 5 - Design by analysis

3/26/2013 58

ASME VIII, Division 1 still the most popular code

In the early days – there were no computers or calculators. Engineers only had slide rules.

Consider a formula for an Ellipsoidal Head thickness from Division 1

Now the analysis for a head from Division 2

3/26/2013 59



3/26/2013 60



Consider a formula for an Ellipsoidal Head thickness from Division 1

Now the analysis for a head from Division 2

A computer is needed to get the head thickness

The advantages of Division 1 rules:

� The calculations are easy to do� Just as important – the calculations are easy to check
