t❑ • ,rFw FIBERGLASS 2.3.1 Preparation When installing a secondary contain- ment system from Smith Fiberglass Products, some preparation is neces- sary if the closest possible separation of lines is required. To minimize the overall change in elevation when in- stalling a containment crossover, it is • i o necessary to shorten one leg of the 450 containment elbow and the side outlet run of the containment tee. Refer to Table 2.3.1 forthemaximum length that can be removed and for the minimum nipple length of both product piping and secondary con- tainment piping. To prevent interference of the pipe- lines, do not locate two containment fittings closer than shown in Table 2.3.2, Figure 2.3.1.
