Neogrevane tlačne posode - 8. del: Dodatne zahteve za tlačne posode iz aluminija in aluminijevih zlitin

Ta del tega evropskega standarda določa zahteve v skladu z Direktivo EU 97/23/ES o tlačni opremi (PED) za uvedbo tehničnih dobavnih pogojev, in sicer v obliki:
– harmoniziranih evropskih standardov za material;
– evropske odobritve za materiale (EAM);
– posebne ocene materialov (PMA)
za kovinske materiale za tlačno opremo v vseh oblikah proizvodov. Ta standard ne zajema dodajnih materialov za varjenje.
OPOMBA: Ta standard je bil razvit predvsem na podlagi jekla. Kljub temu se lahko uporablja tudi za druge materiale, vendar je treba upoštevati posebne vidike zadevnega materiala

Design strength values are given in Tables A.2 to A.5 in Annex A. Design temperatures that exceed the
respective temperature limit in Annex A are not permitted.

For welded parts and heat treated parts after forming only the values equivalent to the O temper shall be used
for design when 6 000 series flanges, etc. are welded. These values are not quoted in EN 12392:2000 and so
the tabulated values for f shown in Table 6.3-2 shall be used for design. The weld area shall be based on the
O temper but the flange strength away from the weld (2t) may be based on the actual temper (T4 or T6).
For aluminium and aluminium alloys values of 0,2 % proof stress (or 1 % proof stress for material
group 21-1 000 series aluminium) for temperatures above 20 °C shall be established by linear interpolation
between two adjacent values in Annex A or in EN 12392:2000 except that for alloys 5083 and 5086 the
respective value at 50 °C may be used for 65 °C.
For material of group 22.4: For short periods, higher temperatures (e.g. when defrosting refrigerating plant) up
to 150 °C are permissible provided that the pressure is reduced to half the working pressure for a period up to
8 h and to atmospheric pressure for a period up to 24 h.

a) There is a strict relationship between the WPS and the mechanical properties obtained in the procedure
approval test for aluminium materials 21, 22.1, 22.3 and 22.4. Because of the tolerance of these
aforementioned aluminium materials to weld procedural variables, production tests are not required if all
of the following conditions are met:
— The quality requirements for welding according to EN ISO 3834-2:2005 or EN ISO 3834-3:2005 are
fulfilled.
— The welding process is fully mechanised (see ISO 857-1) ensuring that the welding procedure is
applied consistently.

2) one test plate per 200 m of longitudinal welds in hemispherical heads in the case of joint coefficient
1,0;
3) one test plate per year where the circumferential welds are welded to a procedure involving joggle
joints or permanent backing strips.
After 10 consecutive test plates have successfully passed the tests, testing may be reduced to the following:

5) one test plate per 1500 m of longitudinal welds in hemispherical heads in the case of joint coefficient
1,0;
6) one test plate per year where the circumferential welds are welded to a procedure involving joggle
joints or permanent backing strips.
The testing of the production test plate shall consider the parameters for the post-weld heat treatment(s) of
the pressure vessel.
