Foreword
This document (CEN/TR 13445-102:2015) has been prepared by Technical Committee CEN/TC 54 “Unfired
pressure vessels”, the secretariat of which is held by BSI.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.

Introduction
Harmonized standards under Pressure Equipment Directive (97/23/EC) have been adopted over the past few
years on the basis of mandate M 071. These standards give appropriate solutions for designing and building
safe pressure equipment complying with the pressure equipment directives.
Although the main standards for the major product groups are now available, further action is needed to
ensure a take-up by industry of these standards.
A recent public consultation on the use of EN Standards in the field of pressure equipment has shown that
better knowledge of content and better usability are the more substantial aspects to encourage the use of the
harmonized European standards (document CEN/PE/AN N 220).
The Pressure equipment Migration Help Desk, EN 13445/MHD, was created in August 2002 to give to the
standard users a central point where raising questions and obtaining authorized answers. From the questions
it received, the help desk has identified the publication of examples of application as a key issue and has
developed rules of procedure for their publication as CEN deliverables (document CEN/PE/AN N 128).
Examples of application is an efficient way to help the standard user to correctly understand and apply the
requirements of the standard and to be aware of the permissible deviations, possible alternatives, use of
normative reference documents, etc. It can also assist training organization and software developers.
The project, in its efforts to broaden the application of the European Standards harmonized for PED, will
support the actions of the European Commission in the field of safety of pressure equipment.
It will also promote the use of these European Standards on the global market.
1 Scope
This Technical Report details the design, manufacturing, inspection and testing of a steel vessel submitted to
pressure cycles, using the EN 13445 series for "Unfired pressure vessels", to guide the user of these
standards in sequential decision making, together with some alternative choices.

3 The vessel and its operating conditions
3.1 Drawing of the vessel
The technical drawing of the vessel and vessel details is represented in Annex A:
A note in the introduction of EN 13445-1, clearly says that "In EN 13445 the term pressure vessel includes the
welded attachments up to and including the nozzle flanges, screwed or welded connections".
The briefed lay-out is given as in Figure 1.
Figure 1 — Briefed lay-out
3.2 Calculation model
The calculation model is presented in 3D in Figure 2.
Figure 2 — Calculation model
3.3 Operating conditions
The general characteristics given by the user are reproduced below:
a) content: gas group 1, density of 0,48;
b) internal pressure: 18 bar / 0,5 bar;
c) temperature: 20 °C/260 °C;
d) number of expected full pressure cycles: 1200.
3.4 Comments on the operating conditions provided by the User
The gas group 1 is a dangerous fluid according to Council Directive 67/548/EEC of 27 June 1967 on the
approximation of the laws, regulations and administrative provisions relating to the classification, packaging
and labelling of dangerous substances.

aspects/58
In the contract 1 200 pressure cycles from 18 bar (1,8 MPa) to 0,5 bar (0,05 MPa) are expected. A design
pressure of 1,8 MPa will not be used to avoid a short duration pressure surge at each cycle (See Pressure
Equipment Directive, Annex I, clause 2.11.2 Pressure limiting devices). Therefore the safety valve will be set
at 2 MPa (pressure higher than 1,8 MPa + 10 %) and the design pressure of 2 MPa will be used in design
calculations for static loadings.
4 Application of EN 13445-1 [1]
4.1 General
This part contains general information on the scope of the standard as well as terms, definitions, quantities,
symbols and units which are applied throughout the standard.
Before designing and manufacturing the vessel according to the standard, the manufacturer shall verify the
applicability of the standard EN 13445 and perform a number of prerequisites.
4.2 Is EN13445 applicable to the vessel?
The answer is yes, since the vessel does not belong to the vessels mentioned in Clause 1 of reference [1]
which are:
 Vessels of riveted construction;
 Vessels of lamellar cast iron or any material not included in part 2, 6 or 8 of the standard;
 Multilayered, autofrettaged or pre-stressed vessels.
4.3 Warning of Annex A of reference [1]
The standard EN 13445 is harmonized under the Pressure Equipment Directive (97/23/EC). This means that if
the vessel meets the requirements of this standard, it can be presumed to conform to those essential safety
requirements which are listed in the Annexes ZA of each individual part.
In this connection, it should be understood that the standard is indivisible. The design and manufacturing of
the vessel requires application of all relevant parts of the standard, in this case of Part 1 General [1], Part 2
Materials [2], Part 3 Design [3], Part 4 Fabrication [4] and Part 5 Inspection and testing [5], since the vessel is
a steel vessel.
Part 7 and Part 9 are not mandatory parts in this sense.
4.4 Prerequisites of Annex A of reference [1]
4.4.1 Operating conditions
Operating conditions provided by the User will be used in the design calculations, but a design pressure of
2 MPa will be used in calculat
