B. row Figure 2 C. Containment Crossover Detail When installing a Smith Fiberglass containment system, some preparation is required to obtain the closest possible Lay out system separation of lines. It is necessary to shorten one leg of with all dry pints. the 45° containment elbow and the side run of the contain- ment tee. Containment Fittings Available containment fittings are 45° elbows, 90° elbows, tees, couplings, and termination concentric reducers (with or without 3/4" NPT threaded outlet). All containment fittings con- sist of two halves. Fittings are assembled with 'A" — 20 standard bolts or 1/4" — 20 carriage bolts, along with Smith Fiberglass adhesive. Car- riage bolts will not require a back-up wrench. (NOTE: Fittings are supplied by Smith Fiberglass without hardware.) The fitting I.D. and flat bonding surfaces are pre -sanded in the factory. Two-piece secondary containment fittings must be bonded with a greater amount of adhesive than is normally used with the bell and spigot joints. (See Figure 3) Adhesive — Apply to •� both halves and to pipe 1116" minimum thickness. 0 O 0: :0 O O Figure 3 t l Make sure gap is completely filled with adhesive. Standard bolts or carnage bolts are 1/4" — 20 x 1.0' long. Standard nuts or wing nuts are 1/4" — 20. All washers are 1/4' standard flat (2 per hole with standard bolts and nuts. 1 per hole with carriage bolts and wing nuts). 514 Refer to Table II for the maximum length that can be removed and for the minimum nipple length of both product (inner) pip- ing and containment piping.

To prevent interference of the pipe lines, do not locate two containment fittings closer than shown in Figure 4. NOTES: 1) The 2.5" critical dimension must be inspected in the field. 2) The 4" minimum O.D.-O.D. horizontal separation is for pea gravel only. If sand is used, a 6" minimum O.D.-O.D. hori- zontal separation is required, and the sand must be well compacted.
