Vessel design pressure

One aspect of pressure vessel design which has received considerable attention in recent years is the design of threaded closures where, due to the high stress concentration at the root of the first active thread, a fatigue crack may quickly initiate and propagate in the radial—circumferential plane. Stress intensity factors for this type of crack are difficult to compute (112,113), and more geometries need to be examined before the factors can be used with confidence.

A pressure vessel designer, on the basis of test, inspection, and experience, says that a vessel has a failure rate less than 1E-6A Y, Experience has already demonstrated 9.3E5VY without failure. What is the estimated failure rate for 95% confidence ... 

Many suppliers of sulfuric acid recommend that it is stored in pressure vessels designed to withstand a gauge pressure of 30 psi (2 bar). The acid is usually discharged from tank trucks by compressed air, and if the vent is ehoked the vessel could be subjected to the full pressure of the compressed air.

The use of standards in design is illustrated in the discussion of the pressure vessel design standards (codes) in Chapter 13. 

For pressure applications the shell thickness would be sized according to the pressure vessel design standards, see Chapter 13. The minimum allowable shell thickness is given in BS 3274 and the TEMA standards. The values, converted to SI units and rounded, are given below ... 

A data sheet for pressure vessel design is given in Appendix G. 

The maximum shear-stress theory has been found to be suitable for predicting the failure of ductile materials under complex loading and is the criterion normally used in the pressure-vessel design. 

The pressure vessel design codes and standards include lists of acceptable materials in accordance with the appropriate material standards. 

The maximum intensity of stress allowed will depend on the particular theory of failure adopted in the design method (see Section 13.3.2). The maximum shear-stress theory is normally used for pressure vessel design.
