6 Dimensions:
7 12.000 ODL [in]- outside diameter of large end
8 8.000 ODS [in]- outside diameter of small end
9 0.250 t [in]- thickness
10 12.000 L [in]-length
11 0.010 Corr [in]- corrosion allowance
12 Material and Con dit ions :
13 SA-240 304 Material
14 20,000 S [psi]- allowable stress
15 1.00 E - long seam efficiency
16 50.0 P [psi]- interior pressure
17 Calculated Propert ies:
18 Approx. cone weight based on steel, lbs = 26.4
19 Approx. cone volume , cuft = 0.5020 a [rad]=
ATAN((ODL-ODS)/(2*L)) ~~alpha angle in radians ATAN((12-8)/(2*12))
= 0.165
21 angle [deg]= Degrees(a) ~~alpha angle in degrees
DEGREES(0.165) = 9.462
22 nt [in]= t-Corr ~~thickness with corrosion allowance removed
0.25-0.01 = 0.240
23 Required Thickn ess:VIII-1 App 1-4 e)
24 Treq [in]=
25 0.025
26 CheckTreq = Treq = 50 = Acceptable
31 T provides a worst case required thickness for nozzle
analysis for a nozzle located on the large end of the cone and
located
32 on the long seam weld.
33 The UG-16(b) minimum thickness requirement has not been taken
into consideration here.
34 Discontinuity checks which are required for each end of the
cone when it is welded to a straight shell are not included
35 in this sheet.
36 This sheet cannot be used to check for allowable exterior
pressure loads.
37 This sheet is for educational use only - use at your own
risk.
