Shallow flanged and dished heads have a shallower dish radius than other head styles.This can save money and room on the overall height or length of the tank you're building,but it also decreases the pressure rating of the tank head,making it unsuitable for ASME code applications.Assessment of an edge type settlement of above ground Nov 01,2007 flat bottom steel tanks Radius Tolerances for the Inner Tank Shell#0183;It is noted that the API standard 635 provides guidelines for measurement of the localized depression type edge settlement and recommends using the following criterion to evaluate the allowable edge deflection limit,S/L 0.03083 (S and L have the same units),where S is plate edge maximum deflection and L is the radial length of the plate settled area as shown in Fig.1.Analysis of displacements and stresses in oil storage DISPLACEMENTS AND STRESSES IN OIL STORAGE TANKS CAUSED BY DIFFERENTIAL SETTLEMENT Table 1 Table of representative values of shell height 1 and radius a for steel tanks,and corresponding approximate values of (a) shell thickness t range,determined from BS 2654 (5),from bottom to top of shell,assuming a design stress of 260 N/mmz,a liquid specific gravity
