Grouping of Boilers and Pressure Vessels: PART 4 CHAPTER 4 SECTOIN 1 – Table #2 and #3 >> Group II
PART 4 CHAPTER 4 SECTOIN 1 Appendix 1 – Rules for Design Cylindrical Shell Design Information Design Pressure: 10 [Bar] / 1 [Mpa] Design Temperature: 65°C Shell Outside Diameter (new): 762.00 mm Shell Outside Diameter (corroded): 762.00 mm Shell Length: 1200 mm. Shell actual THK = 10.0 [mm]
Shell Material: SA-516 G70, All. stress for plate at 20⁰C mm =137.9 MPa All. stress for plate at 65⁰C mm =137.9 MPa = Inside Corrosion Allowance: 0.00 mm External Corrosion Allowance: 0.00 mm
Nozzle Material: SA-106 B All. stress for pipe at 20⁰C mm =117.9 MPa All. stress for pipe at 65⁰C mm =117.9 MPa = Inside Corrosion Allowance: 0.00 mm External Corrosion Allowance: 0.00 mm
Nozzle Efficiency: 85 %
Eefficiency of shell at nozzle: 100 % UG-45 Thickness Calculations Nozzle Thickness for Pressure Loading (plus corrosion) per Paragraph UG-45(a) Directed to (ABS 4-4-1 App1 Eq:1) or (ASME Paragraph UG-27(c)(1))
Nozzle Thickness for Internal Pressure (plus corrosion) per Paragraph UG-45(b)(1) Directed to (ABS 4-4-1 App1 Eq:3) or (ASME Paragraph UG-27(c)(2))
Minimum Thickness of Standard Wall Pipe (plus corrosion) per Paragraph UG-45(b)(4) = 8.34 (Table UG-45)+0+0=8.34
Nozzle Minimum Thickness per Paragraph UG-45(b)
Pipe Size: 10 Schedule: 30 – Wall Thickness = 9.53 [mm] Nozzle is adequate for UG-45 requirements
