a An alternate method of pipe end preparation is sanding with 40-60 grit sandpaper to remove all surface gloss. Belt sanders or a coarse cut flat file may be used. The sanded length must be a minimum of 33/4". B. Pipe Assembly The containment pipe must be positioned over the product pipe prior to bonding of the product pipe. After testing of the product pipe, the containment fittings should be installed and the containment system tested. Typically, the length of the containment system is determined from: L = (OAL of Product Piping) – (B) NOTE: When terminating with a concentric reducer, use the C dimension instead of the B dimension in the table below.

It is helpful to lay out We system, cut, taper and dry fit all product lines. Where possible, place containment fitting halves under the product fittings. (See Figure 3) Q r_tZZ Lay out system ?� with all dry joints. Figure 3 C. Fittings Assembly All containment fittings consist of two halves with flanged tabs', as shown in Figure 3. Fittings are assembled with 1/4"— 20 NC hex head bolts along , with Smith Fiberglass Products adhesive. (NOTE: Fittings!L are supplied by Smith Fiberglass Products without! hardware.) The fitting 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 of product;' piping. (See Figure 4) 2 Hex head bolts are 1/4" — 20 NC x 1.0" long. Standard nuts are 1/4" — 20 NC. All washers are 1/4" standard flat (2 per hole). D. Bonding and Assembly (For Containment Piping) Use only DS -7014 or DS -7069 adhesive manufactured by Smith Fiberglass Products for installation of Smith Fiberglass Products containment piping systems. TABLE II Bonding of Containment Fittings DS -7014 Kit DS -7069 Kit Type of Fitting (Approx. Fittings per Kit) (Approx. Fittings per Kit) Refer to bonding procedures in Manual 1055 for adhesive mixing and surface cleaning. Thoroughly mix all of the adhesive base with all of the adhe- sive hardener. Do not attempt to split a kit. The adhesive should have a uniform consistency and flow smoothly off the mixing stick. Filler must be added to thicken the adhesive. The filler is packaged in premeasured quantities for use with DS -7014 or DS -7069 adhesive kits and is available from your local Smith Fiberglass Products distributor. Filler should be added in three steps, thoroughly mixing between additions. All of the filler in the bag should be used. NOTE: Adhesive and hardener must be thoroughly mixed before adding the filler. 3" 4" 3" 4" 6" 90° Elbow 11/t 1 21k 11h 1 45° Elbow 2 1 3 2 1 Tee 1 1 2 11/2 1 Coupling 2 1 3 2 i Termination Concentric Reducer 2 1 3 2 1 Refer to bonding procedures in Manual 1055 for adhesive mixing and surface cleaning.
