A. Determine the length of the pri- mary pipe. B. Determine the fittings to be used on each end of the primary pipe. Find the corresponding numbers in Table 2.2.1 (X1 for first fitting, and X2 for the second fitting); sub- tract them from the OAL. This will be length of the containment pipe. Example: If 2" (50mm) product pipe is 20 ft., 6 in. (6,248mm) long, and you are using a 90" elbow on one end and a 45" elbow on the other end, then cut the containment pipe 20 ft., 2 in. (6,147mm). WARNING: Since every insertion of the primary piping may vary, dry fit all secondarK containment connec- tions to make sure that the insertion is approximately 3". Be sure that the containment pipe is not inserted too far into the containment fitting. The glossy O.D. of the pipe should not be seated in the containment fitting. 2.2.4 Fitting assembly All containment fittings consist of two halves with flanges as shown in Fig - Calculation: 20'6" - 2-1/8" (fitting #1, 90° ell) - 1-7/8" (fitting #2, 450 ell) = 20'2" or 6,248mm - 54mm (fitting 91, 900 ell) - 48mm (fitting #2, 45° ell) = 6,147mm ure 2.2.3. The bottom half has threaded inserts for ease of assembly. These fittings are assembled with adhesive and 1/4_20 washer -head bolts that are furnished with the fit- tings. The required bolts are supplied in small plastic bags. If extra bolts are required, these can be purchased from your distributor or standard 1/4-20 x 1 -inch long hex head bolts can be used. If standard bolts are used, place a flat washer on the bolt before torqu- ing. 28 The bonding surfaces of the contain- ment fittings are supplied from the factory pre -sanded. Two-piece sec- ondary containment fittings must be joined using a greater amount of ad- hesive than is necessary for joining bell and spigot joints of product pip- ing. See Figure 2.2.5.
