Safety by Design
Mechanical integrity ………. safety in the design phase ………. safety in the manufacturing phase ………. safety in the field operation phase
Leading Technologies and Services
for a Safe Plant Operation
Slide 1 Alain ENGELS

Safety BY DESIGN – A life time commitment
• Endress+Hauser design standards
• Material selection
• Design simulations using “Finite Element Methods”
• Mechanical design stress testing
• Welding Procedure Specifications
• Sealing concepts
• Inherently safer designs
Mechanical integrity ……….safety in the design phase
Slide 2 Alain ENGELS

Endress+Hauser design standards
Slide 3
• Design and testing experience
built on generations of product
history within Endress+Hauser ,
Endress+Hauser customers and
industry/academic organizations
• Costly and unproductive
complexity is avoided by
standardized development across
all Endress+Hauser operations
• These standards help
Endress+Hauser reduce risk in the
design, manufacturing and
documentation of products, in turn
helping us reducing risks to our
customers
Alain ENGELS
23/04/2015
Material selection
Metals • The selection of the correct type and form of metals used within
an instrument is built on years of experience and testing.
Plastics/elastomers • A wide variety of non metallic polymer materials are available
for seals, containment, insulation, etc
Glass/ceramics • Non-metallic materials such as glasses, graphite, ceramics are
typically selected for seals, insulation, etc. for demanding
service especially under higher temperatures and pressures
Heterogeneous assemblies • Assemblies with combinations of materials can have complex
interactions that must be suitable for the design service.
• Understanding how the combination of forms and compositions
will behave are critical to achieving a low risk service design.

Design Simulations
Endress+Hauser uses the latest design FEA tools to
simulate real world effects (i.e. fatigue, failure) on
designs from mechanical forces, heat, vibration, fluid
flow and other physical stresses to reduce risk.

Finite Element Methods
23/04/2015
Stress testing
Vibration testing • Testing of prototype components or final products to ensure the final
design will provide expected resistance
• Amplitude and frequencies (g forces) are varied in X, Y and Z directions
Shock testing • Subjecting components or final products to abrupt forces or strikes to
test integrity as specified
Fatigue testing • Some components in a design subjected to mechanical movement over
time may develop weaknesses leading to failure
• Repetitive flexing or mechanical movement may be conducted over a
period of time to ensure the right material for the design is used
Burst testing • Testing is conducted on a component or final product to pinpoint the
level at which function or containment is lost
Slide 6 Alain ENGELS
23/04/2015
Welding procedure specifications
Welding Procedure Specifications (WPQR & WPS) are managed
according to required standards
Clear and transparent guidelines prevent defective work in
manufacturing and customer documentation.
Slide 7 Alain ENGELS
23/04/2015
Sealing concepts Instruments by their nature are often installed in
hazardous areas, inserted into extreme process pressures,
temperatures and exposed to all types of materials
An instrument needs to be robust enough to avoid a
release of process material or needs to be predictable in
how it releases process material so risk is managed
Showing a customer the complexity in a cross section
picture or model of some of our instruments may help
them grasp there is more mechanical design built in than
what appears from the outside

intrusive / non-invasive instrument designs • Radiometric level and density measurements

Safety BY DESIGN – A life time commitment
• Manufacturing quality assurance
• Material traceability
• Positive Material Identification (PMI)
testing
• Radiographic (RT) testing
• Dye penetrant (DPI) testing
• Welding Procedure Qualification Reports
• Hydrostatic pressure testing
• Helium leakage testing
Mechanical integrity ... Safety in the manufacturing phase
Slide 10 Alain ENGELS
23/04/2015
Manufacturing quality assurance
• The quality assurance systems at Endress+Hauser are based on ISO
defined criteria and are regularly audited by outside agencies.
• ISO 9001 Quality Management System
• ISO 14001 Environmental Management System
• OHSAS 18001 Occupational Health and Safety Management System
• Each employee in our organization shares the responsibility for
consistently producing the products expected by our customers
• Dedication to quality and continuous quality improvement is cultural
at Endress+Hauser….and our safety message as well!

Slide 11 Alain ENGELS
23/04/2015
Material traceability
• Maintaining absolute material identification, inventory and
traceability from incoming stock to finished delivered product and
documentation is a core strength of Endress+Hauser manufacturing.
• Material traceability and sometimes proof of traceability is required
by process plant engineering and construction operations to ensure
predictable containment integrity
Slide 12 Alain ENGELS
23/04/2015
Positive Material Identification (PMI)
• Endress+Hauser uses PMI testing as a non-destructive method which does not
affect the material properties. It is not a substitute for a traceability certificate
• PMI testing is performed by emitting X-rays on the material to be tested, which
then responds by sending out XRF (X-ray fluorescence) signals of varying energy
and intensity depending on its chemical composition. The XRF signals are then
recorded by an XRF analyze
• Studies show that in Petrochemical and Refinery facilities almost half of the
largest losses are a direct result of failures in piping systems. PMI testing is
commonly used method to eliminate any material mixing errors
Slide 13 Alain ENGELS
23/04/2015
Radiographic (RT) testing
• Endress+Hauser uses industrial radiography or
X-ray testing to inspect materials for hidden flaws
to reduce risk
• Reveals material defects (visible as well as hidden)
on metallic materials .
• Especially well suited for welding seam analysis
since even very small defects can be identified.
• Non-destructive as it does not affect the material
properties or leave any marks on the measured
surface.
• Report generated by qualified Endress+Hauser
personnel is included with the instrument
documentation when specified
Slide 14 Alain ENGELS
23/04/2015
Dye penetration (DPI) testing
• Dye Penetrant Inspection (DPI), also called Liquid Penetrant
Inspection (LPI) or Penetrant Testing (PT), is used by
Endress+Hauser to locate surface-breaking defects in all non-porous
materials
• LPI is used to detect casting, forging and welding surface defects such
as hairline cracks, surface porosity, leaks in new products, and
fatigue cracks on components
Slide 15 Alain ENGELS
23/04/2015
Welding procedure qualification
• Welding seams on many Endress+Hauser products are produced by automatic
welding machines according to instrument specific WPQR/WPS (Welding
Procedure Qualification Record/Welding Procedure Specification) and
supervised/controlled by approved welding engineers.
• Frequent inspection of both welding machines and the resulting welding seams are
conducted to maintain the highest quality demands and regulatory requirements.
• Customers can fully rely on the welding seam quality of any Endress+Hauser
welded device
Slide 16 Alain ENGELS
23/04/2015
Hydrostatic pressure testing
• Hydrostatic testing is a safer way to verify the integrity of a
manufactured instrumentation component that is designed for
pressure service.
• Many Endress+Hauser components are 100% tested while others are
tested to meet specific customer or industry requirements
Slide 17 Alain ENGELS
23/04/2015
Helium leakage testing
• Leak testing is part of the
Endress+Hauser non-
destructive test NDT portfolio
that can be applied to a
fabricated component to verify
it is leak proof
• For example, Liquiphant
extensions are 100% Helium
tested to ensure component
welding is fully accomplished
and there are no leak points
