For the pressure vessel defined in the problem

Chapter 8, Problem 8-41

(choose chapter or problem)

For the pressure vessel defined in the problem specified in the table, redesign the bolt specifications to satisfy all of the following requirements.

• Use coarse-thread bolts selecting a class from Table 8–11 for Probs. 8–41 and 8–43, or a grade from Table 8–9 for Probs. 8–42 and 8–44.

• To ensure adequate gasket sealing around the bolt circle, use enough bolts to provide a maximum center-to-center distance between bolts of four bolt diameters.

• Obtain a joint stiffness constant C between 0.2 and 0.3 to ensure most of the pressure load is carried by the members.

• The bolts may be reused, so the yielding factor of safety should be at least 1.1.

• The overload factor and the joint separation factor should allow for the pressure to exceed the expected pressure by 15 percent.
