Process Equipment and Plant Design
In a cylinderical vessel subjected to internal pressure, the longitudinal stress σL and the circumferential stress, σh are related by
Minimum tube sheet thickness (in which tubes are fixed) is equal to the O.D. of the tube upto 15 mm tube diameter; and for > 15 mm tube diameter, tube sheet thickness is smaller than tube diameter
Minimum cleaning lane of 6.5 mm is provided, when tubes are on a square pitch
All of these
O.D. of the tube is 6 to 40 mm while the tube lengths used are 0.5, 2.5, 3.0, 4.0, 5.0, 6 metres
