gasketed end plate

Repeat Problem 10.42 except that the gasket clamping pressure is 10 MPa.

 

Problem 10.42

Figure P10.42 shows a pressure vessel with a gasketed end plate. The internal pressure is sufficiently uniform that the bolt loading can be considered static. The gasket supplier advises a gasket clamping pressure of at least 13 MPa (this includes an appropriate safety factor) to ensure a leak-proof joint. To simplify the problem, you may neglect the bolt holes when calculating gasket area.

(a) If 12-, 16-, and 20-mm bolts that have coarse threads and are made of SAE class 8.8 or 9.8 steel (whichever is appropriate) are to be used, determine the number of bolts needed.

(b) If the ratio of bolt spacing to bolt diameter should not exceed 10 in order to maintain adequate flange pressure between bolts, and if this ratio should not be less than 5 in order to provide convenient clearance for standard wrenches, which of the bolt sizes considered gives a satisfactory bolt spacing?
