26、metrically 3.2 Pressure vessel data The data specified for the present example are the following: Vessel data: PD CEN/TR 13445-101:2015 CEN/TR 13445-101:2015 (E) 6 Key D i = 3 468 mm L = 20 000 mm (cylindrical shell length) Figure 1 Pressure vessel data Material: steel Service data: Normal service c

27、onditions: Internal pressure: 44 bar Maximum temperature: 50 C Minimum metal temperature: -20 C Liquid group 1, density: 0,54 Pressure loading predominantly of non-cyclic nature There are not exceptional service conditions. PED 97/23/CE regulation applies. The calculation of all components is perfor

28、med by formulas (DBF: Design By Formula). According to the specified operating conditions, the pressure vessel is neither subjected to fatigue nor to creep. It is supposed that there is only a risk of atmospheric corrosion during operation of the vessel. Thus, a corrosion allowance of 3 mm is added.

29、 PD CEN/TR 13445-101:2015 CEN/TR 13445-101:2015 (E) 7 3.3 PED 97/23/CE Category The maximum allowable pressure PS used as a first approach is 44 bar and the fluid is a liquid of group 1. The category which applied for the target vessel is category II as defined in Clause 3 paragraph 1.1(b) of the PE

30、D which indicates the use of Table 3 of Annex II of PED to set the category. 3.4 Extracts from EN 13445-1 to EN 13445-5:2009 and from others standards The extracts from the EN 13445 Standard clauses which are the most relevant at each step of the example are reproduced in black frames. When necessar

31、y, the adequate requirements in these extracts are framed in red. Other extracts of standards referenced in EN 13445 are reproduced, also in black frames, and the standard from which they are extracted is mentioned. When necessary, the adequate requirements in these extracts are framed in red. 4 Mat

32、erials 4.1 General EN 13445-2:2009 gives the minimum requirements to be fulfilled for steel entering the manufacturing of pressure vessel. The informative Annex E of this standard references European materials usable for pressure vessel manufacturing. The corresponding steel grades come from harmoni

33、zed European standards. The Grouping according to CEN ISO/TR 15608:2000 is also given for each grade. The minimum requirements concern elongation, impact test and chemical composition. These requirements for steel should ensure toughness and good behaviour of materials during manufacturing (weldabil

34、ity and forming). Table 4.1-1 of this report summarizes some properties of the materials which have been chosen for fabrication of the target vessel. This table shows how the requirements of EN 13445-2:2009 are fulfilled. 4.2 Minimum requirements for materials 4.2.1 General The following clauses of

35、EN 13445-2:2009 shall be fulfilled: 4.2.2 Minimum elongation The requirements for minimum elongation are fulfilled by the chosen materials, see Table 4.1-1. Figure 2 Abstract from EN 13445-2:2009 PD CEN/TR 13445-101:2015 CEN/TR 13445-101:2015 (E) 8 4.2.3 Impact test for ferritic steel The requiremen

36、ts for impact test are fulfilled by the chosen materials, see Table 4.1-1. Requirements of Annex B of EN 13445-2:2009 shall also apply; see 4.5 of this report. Figure 3 Abstract from EN 13445-2:2009 4.2.4 Chemical composition of selected grade The requirements for chemical composition are fulfilled

37、by the chosen materials, see Table 4.1-1, except for the bolting grade 42CrMo4 (1.7225), but this product is not intended for welding or forming as stated in 4.1.7 of EN 13445-2:2009. Indeed, following EN 10269:1999, EN 10269:1999+A1:2006, the specified chemical composition for this grade of bolting

38、 is: %C: 0,38 to 0,45; % P: 0,035 max; % S: 0,035 max. PD CEN/TR 13445-101:2015 CEN/TR 13445-101:2015 (E) 9 Figure 4 Abstract from EN 13445-2:2009 4.3 Mechanical properties of the chosen materials The selected grades and their appropriate properties are summarized in Table 4.1-1. All the mechanical

39、properties presented in this table are minimum values from transversal specimen and are specified in the relevant technical specification. Transversal specimens are defined as specimen taken in a direction perpendicular to the direction of principal deformation of the product (e.g. for flat products

40、 the transversal direction is perpendicular to the rolling direction). Since the minimum yield strength and tensile strength values are specified in the material technical specification as a function of the product thickness the values to be used for the design of each specific component are not kno

41、wn at first. They can be set only once the design calculations performed according to the relevant EN 13445-3:2009 rules have shown that the thickness assumed for calculation is acceptable. In some cases an iteration on the thickness and the corresponding mechanical properties is necessary to get th

42、e correct values (see Clause 5 of this report). For determination of the material characteristics above 20 C, the interpolation rules which apply are those defined in 4.2.2 of EN 13445-2:2009: PD CEN/TR 13445-101:2015 CEN/TR 13445-101:2015 (E) 10 Figure 5 Abstract from EN 13445-2:2009 PD CEN/TR 1344
