From Pressure Vessels : ASME Code Simplified, Eighth Edition
An attempt is made in this chapter to assist those wishing to find specific information quickly without having to wade through the large fund of specifications and recommendations encompassed by the Code. Figures and tables outline designs, materials, or performance requirements, indicate conditions for which precautions are necessary, and list Code paragraphs to be read for the proper information. Experience has proven that many of these items are often overlooked. Also included is a handy reference chart (Fig. 2.1) that graphically illustrates the various parts of a pressure vessel and the Code paragraphs that apply to each. Table 2.1 lists the various classes of materials from Section VIII, Division 1, the covering Code section part, applicable references for the stress value tables found in Section II, Part D, and additional helpful hints. It should be remembered, however, that there is no substitute for reading the Code itself.
