A cylindrical pressure vessel with 1m inner diameter is subjected to internal steam pressure of 1.5 MPa. The permissible stresses for the cylinder plate and rivets in tension, shear and compression are 80, 60 and 120 N/mm? respectively. The efficiency of longitudinal joint can be takes as 80% for the purpose of calculating the plate thickness. The efficiency of circumferential lap joint should be at least 62%. Design the circumferential lap joint and calculate: а. thickness of the plate b. diameter of the rivets С. number of rivets d. pitch of rivets е. number of rows of rivets; and f. overlap of the plates A cylindrical pressure vessel with 1m inner diameter is subjected to internal steam pressure of 1.5 MPa.
