Metallic industrial piping - Part 2: Materials
This part of EN 13480 covers the requirements for materials (including clad materials) for industrial piping and supports covered by EN 13480-1 constructed of metallic materials and is currently limited to steels with sufficient ductility below the creep range. It specifies the assessment of compliance for these materials. It also provides rules for the establishment of technical delivery conditions for materials for industrial piping.

Annex B
(normative)
Requirements for prevention of brittle fracture at low temperatures
B.1 General
This annex distinguishes between pressure equipment that has design temperature for normal operation
higher or lower than 50 °C.
For pressure equipment with normal operation temperatures higher than 50 °C B.5 applies. If B.5 is not
applicable, the following rules for lower normal operation temperatures shall be used.
For pressure equipment with design temperature equal to or less than 50 °C this annex specifies three
1)
alternative methods for establishing criteria for the prevention of low temperature brittle fracture of steels in
the form of plate, strip, tubes, fittings, forgings, castings, flanges, fasteners and weldments used in pressure
parts. In this case, the temperature for the design T shall be determined . The criteria are based on impact
R
energy requirements at specified temperatures for the base material, heat affected zone (including the fusion
line) and weld metals.
The three methods are:
Method 1 Code of Practice:
Technical requirements
a) based on the assumption that T = T as specified in harmonised European Material
R 27J
Standards and that it is possible to achieve these minimum properties after fabrication;
b) calculated from the principles of fracture mechanics used for Method 2 for C and CMn steels
with yield strength < 460 N/mm and
c) based on operating experience for Ni-alloyed steels with Ni > 1,5 % up to 9 %, for austenitic
steels and for bolts and nuts.
Method 2 Method developed from the principles of fracture mechanics and from operating experiences:
A more flexible approach than Method 1 for derivation of technical requirements applicable to C,
CMn and low alloy ferritic steels with a specified minimum yield strength ≤ 500 N/mm and for
austenitic-ferritic steels with a specified minimum yield strength ≤ 550 N/mm . This method can
be applied for these steels to a wider range of thicknesses and temperatures than Method 1
because T must not be equal to T (see Figures B.2–1 to B.2–11). In addition for ferritic
R 27J
steels with max. 355 N/mm in PWHT condition operation experience was considered for
higher thicknesses.
Method 3 The application of a fracture mechanics analysis:
This general method is applicable to cases not covered by methods 1 or 2. This method may
also be used to justify deviations from the requirements of Method 1 or 2. Only general
1)
Including temperatures at pressure tests
See EN 13480-2:2002, 3.1.3.
guidance is given on the use of this method which shall only be used in agreement with the
parties concerned.
Each of the three methods may be used independently. It is only necessary to satisfy the requirement of any
one method.
All applicable combinations of the temperatures T (minimum metal temperature) and T (temperature
M S
adjustment term) shall be considered and the lowest possible T -value (design reference temperature) shall
R
be used for the determination of the required material impact test temperature.
NOTE For definitions of temperature terms see 3.1.1 to 3.1.4.
B.2 Material selection and impact energy requirements
The methods specified in B.2.1 (Method 1) or B.2.2 (Method 2) shall be used to determine the impact energy
required to avoid brittle fracture. Alternatively, B.2.3 (Method 3) may be used to determine the required
toughness. The method used shall be fully documented, in order to ensure that compliance can be verified.
Reference thickness for constructional details is defined in Table B.5-1.
B.2.1 Method 1
B.2.1.1 General
Method 1 allows the selection of materials taken from harmonised European material standards with regard to
prevention of brittle fracture. Table B.2–1 gives an overview to the following tables by steel type and product
form.
The weld metal, the heat affected zone and other parts affected by manufacturing processes shall satisfy the
same impact energy requirements as the guaranteed minimum properties for the base material at T given in
R
the tables.
The tables list design reference temperatures for maximum thickness at given strength levels represented by
steels from h
