Elliptical Head From 10 To 20 SA-240 304 at 400 C
Thickness Due to Internal Presión [Tr]:
= (P*(D+2*CA)*K)/(2*S*E-0.2*P) Appendix 1-4(c)
= (35000.000*(58.0000+2*0.0000)*1.00)/(2*106.79*1.00-0.2*35000.000)
= 9.8271 + 0.0000 = 9.8271 mm.
Max. All. Presión de trabajo at Given Thickness [MAWP]:
= (2*S*E*(T-Ca))/(K*(D+2*Ca)+0.2*(T-Ca)) per Appendix 1-4 (c)
= (2*106.79*1.00*(12.0000))/(1.00*(58.0000+2*0.0000)+0.2*(12.0000))
= 42431.543 KPa.
Maximum Allowable Pressure, New and Cold [MAPNC]:
= (2*Sa*E*T)/(K*D+0.2*T) per Appendix 1-4 (c)
= (2*137.90*1.00*12.0000)/(1.00*58.0000+0.2*12.0000)
= 54791.520 KPa.
Actual stress at given pressure and thickness [Sact]:
= (P*(K*(D+2*CA)+0.2*(T-CA)))/(2*E*(T-CA))
= (35000.000*(1.00*(58.0000+2*0.0000)+0.2*(12.0000)))/(2*1.00*(12.0000))
= 88.088 N./mm?
Required Thickness of Straight Flange = 11.832 mm.
Percent Elongation per UHA-44 (75*tnom/Rf)*(1-Rf/Ro) 75.630 %
Cylindrical Shell From 20 To 30 SA-240 304 at 400 C
Thickness Due to Internal Pressure [Tr]:
= (P*(D/2+Ca))/(S*E-0.6*P) per UG-27 (c)(1)
= (35000.000*(58.0000/2+0.0000))/(106.79*1.00-0.6*35000.000)
= 11.8318 + 0.0000 = 11.8318 mm.
Max. All. Presión de trabajo at Given Thickness [MAWP]:
= (S*E*(T-Ca))/((D/2+Ca)+0.6*(T-Ca)) per UG-27 (c)(1)
= (106.79*1.00*(12.0000))/((58.0000/2+0.0000)+0.6*12.0000)
= 35398.691 KPa.
Maximum Allowable Pressure, New and Cold [MAPNC]:
= (SA*E*T)/(D/2+0.6*T) per UG-27 (c)(1)
= (137.90*1.00*12.0000)/(58.0000/2+0.6*12.0000)
= 45710.055 KPa.
Actual stress at given pressure and thickness [Sact]:
= (P*((D/2+CA)+0.6*(T-CA)))/(E*(T-CA))
= (35000.000*((58.0000/2+0.0000)+0.6*(12.0000)))/(1.00*(12.0000))
= 105.589 N./mm?
Percent Elongation per UHA-44 (50*tnom/Rf)*(1-Rf/Ro) 17.143 %
Elliptical Head From 30 To 40 SA-240 304 at 400 C
Thickness Due to Internal Pressure [Tr]:
= (P*(D+2*CA)*K)/(2*S*E-0.2*P) Appendix 1-4(c)
= (35000.000*(58.0000+2*0.0000)*1.00)/(2*106.79*1.00-0.2*35000.000)
= 9.8271 + 0.0000 = 9.8271 mm.
Max. All. Working Pressure at Given Thickness [MAWP]:
= (2*S*E*(T-Ca))/(K*(D+2*Ca)+0.2*(T-Ca)) per Appendix 1-4 (c)
= (2*106.79*1.00*(12.0000))/(1.00*(58.0000+2*0.0000)+0.2*(12.0000))
= 42431.543 KPa.
Maximum Allowable Presión, New and Cold [MAPNC]:
= (2*Sa*E*T)/(K*D+0.2*T) per Appendix 1-4 (c)

= 54791.520 KPa.
Actual stress at given presión and thickness [Sact]:
= (P*(K*(D+2*CA)+0.2*(T-CA)))/(2*E*(T-CA))
= (35000.000*(1.00*(58.0000+2*0.0000)+0.2*(12.0000)))/(2*1.00*(12.0000))
