2.3.1 Preparation <br />When installing a secondary contain- <br />ment system from Smith Fiberglass <br />Products, some preparation is neces- <br />sary if the closest possible separation <br />of lines is required. To minimize the <br />overall change in elevation when in- <br />stalling a containment crossover, it is <br />Containment <br />Pipe Size <br />(in.) (mm) <br />3 75 <br />4 100 <br />6 1S0 <br />necessary to shorten one leg of the <br />45° containment elbow and the side <br />outlet run of the containment tee. <br />Refer to Table 2.3.1 for the maximum <br />length that can be removed and for <br />the minimum nipple length of both <br />product piping and secondary con- <br />tainment piping. <br />To prevent interference of the pipe- <br />lines, do not locate two containment <br />fittings closer than shown in Table <br />2.3.2, Figure 2.3.1. <br />TABLE 2.3.1 <br />CONTAINMENT CROSSOVER INFORMATION <br />Remove from <br />45° Crossover <br />Elbow <br />(Max. in.)
