ABSTRACT
The design basics for design of internal and external nonpressure parts connected to pressure vessels are most vital for competitive manufacturing and safe working of pressure vessels, which are covered in this chapter. For optimum coverage, this chapter begins with an explanation of basics difficult to feel such as the free body diagram, transfer and rotation of vectors, Poisson’s ratio, and moment of inertia (MI). It covers design theories, loads, stresses, design methods, and elastic failure theories. While covering the above topics, more emphasis is given to difficult topics such as plastic theory and shear stress. Derivations are covered for MI, beam theory, and deflection. Examples are included for Poisson’s ratio, MI, and shear stress for clarity of equations. The derivation of a continuous beam is substantiated with an example of a long shell with three saddles. Steps in mechanical design of equipment are briefly explained.
