### Requirement ASME for Design Calculation

Design calculation of steam boiler should be performed carefully. Engineers who have responsibility to design steam boiler shall have good understanding about requirement ASME BPV Section I not only for materials, but also for design calculation.

Design calculation ideally should follow ASME Code. The following below is summary of requirement ASME for design calculation:

- General Design, see ASME BPV Section I sub chapter PG 16
