According to IS 4049 (Part-2): 1996 and Table 2 Dimensions for Dished and Flanged Ends (Torispherical) Inside Crown Radius is 80% of ID Inside knuckles Radius is 10% of ID and in no case less than 6% nor less than 3 x thickness of Dish. Inside height of Dish can be calculated according to IS: 2825 – 1969 and IS 4049 (Part-2) : 1996 as follows: Now the Inside height can be calculated according to IS: 4179 – 1997 which is as follows: When Knuckle Radius is 10% of ID 2. When Knuckle Radius is 6% of ID Where h i = Inside height of Dish R i = Crown Radius of Dish r i = Knuckle radius of Dish D i = Inside diameter of Dish S f = Straight Flange length of Dish Minimum length of straight flange shall be 3 x thickness of Dish or 20 mm but not exceed 38 mm except when necessary to provide required length of taper.
Chemical Process Equipment & Plants Design include a number of important equipment such as Reactors, Ribbon Blender, Rotary Dryer, Rotary Kiln, Air Classifying Mill, Ball Mill, Bucket Elevator, Screw Conveyor, Belt Conveyor, Rotary Vacuum Dryer, Agitated Natuch Filter & Dryer, distillation columns, absorbers, heat exchangers, evaporators, crystallizers, etc. Design of such equipment should be carried out a priory to set-up a process plant.
