Calculation method
Thread Content
Horizontal vessel, nitrogen cushioning. Inner diameter 1200 mm, length 3000 mm, thickness 90 mm. Design pressure 16 MPa, design temperature 200°C. Material: Q345R. Spherical head; the right head is designed according to Figure f on page 291 of standard 150, with a dimension of 54 mm, resulting in an inner diameter of the spherical head of 1236 mm. May I ask how to calculate the strength of the right head? The left spherical head is set at 90 mm, as an access hole needs to be provided in the center. The manhole is designed according to page 203, figure 7-11 of standard 150. May I ask about the strength calculation for the cylinder ends and end caps? Thank you!
Determine the thickness based on an inner diameter of 1236, and then carry out calculations for reinforcement through the openings.
Strength calculation for cylinder ends and end caps?
In 150.3, 7.7.4.3 refers to the calculations for the end of the cylinder; the end caps are calculated in accordance with Appendix C of 150.3.
