Seamless EO Stainless Steel Tubes Material-No.: 1.4571
Table Q4 — Seamless EO stainless steel tubes
Pressure Calculation:
Pressure calculation given are according to DIN 2413 part I
for
static stress
Material characteristic value K=245 N/mm
2
(1.4571),
K=245
N/mm
2
(1.4571) (1%
proof stress)
Safety factor S = 1.5
Factor “c” for consideration of wall thickness divergence: 0.9
da = Tube O.D. in mm
s = Wall thickness in mm
Remarks:
Corrosion
Additional allowances are not considered for
the calculation of pressures.
Tubes with a diameter ratio da/di
=
1.35
are calculated
according to DIN 2413 part III (formula see page Q5) with
above characteristic K value.
Conversion Factors:
Bar x 14.5 = psig
