SCARFING PIPE All piping should be scarfed before bonding. Couplings may be needed for making containment pipe size reductions or straight pipe runs. Spigots may be needed for pipe runs or for making a containment sump connection. The ends of the containment pipe that are to be joined to secondary containment fittings must be thoroughly scarfed for a minimum length of 3 inches (75 mr-n). See page 3 for scarfing tools available or refer to Bulletin Nos. F6624, F6625, or F6600 for complete operating instructions.

If there is a gap between the clam shell fitting halves when assembled by hand, pipe must be scarfed more. --Ij-- f Properly scarfed ends are most easily accomplished by using the Model 2100 power tool. Preset at the factory, it can scarf 3" and 4" (75 mm and 100 mm) Red Thread IiA secondary containment pipe. It also tapers 2" and 3" (50 mm and 75 mm) Red Thread IIA primary pipe. If the Model 2100 or 2102 power tool is not available, the ends may be scarfed using the manual tapering tool in conjunction with a secondary containment scarfing adapter kit. This kit consists of a special scarfing blade (approximately 4"/100 mm long), scarfing blade holder, 1/8" Allen wrench, and 3" and 4" (75 mm and 100 mm) scarfing gauges, that are required to set the tool tolerances. The scarfing adapter kit is easily adapted to the 2"-6" (50 mm -150 mm) manual tapering tool kit. Assemble the proper size mandrel and scarfing blade holder following the procedures in Manual No. F6600, Installation Instruction for 1 "-6" Tapering Tool. Rotate the tool body so that the scarfing blade holder is at a 12 o'clock position. this assures the blade will rest on top of the gauge. Slide the proper size gauge all the way to the back of the mandrel. Insert the special blade into the blade holder all the way to the back of the tool body. After positioning the black reference mark on the gauge under the blade, be sure the blade makes uniform contact with the gauge and the blade holder is resting on the blade. Using the nuts, bolts, and washers supplied, tighten the blade holder to secure the blade. Now insert and slide the bearing plate into the slot located between the tool body and the blade holder. The bearing plate will rest loosely on the blade holder until it is locked into place using the supplied Allen screws. The two Allen screws should now be positioned so each makes LIGHT contact with the bearing plate. The Allen screws only prevent the blade holder from opening during use. The tool is now prepared to remove (scarf) the resin gloss from the ends of the containment pipe. After removing the gauge, insert the tool into the pipe to be. scarfed until the point of the blade touches the end of the pipe. The tool must be rotated in the same direction the wide side of the blade faces. Advance the tool In approximately'/a" (6 mm) increments after each revolution. Continue the operation until the resin gloss has been removed for a minimum length of 3" (75 mm). PIPING LAYOUT Pre -installation of the secondary containment pipe is best accom- plished at the same time the product pipe is dry fitted , together. a Lay out system with all dry joints Typically, the length of the CrWwt fte containment pipe should be 4" con "I Pi shorter than the primary pipe. \pe r ri . IL _ WARNING: Fit all secondary containment connections to make sure the insertion is approximately 3". Be sure 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 oontainment fitting. CONTAINMENT FITTINGS All containment fittings consist of two halves with flanges. 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 fittings. The required bolts are supplied in small plastic bags. If extra bolts are required, they can be purchased from your distributor or standard '/4-20 x 1 " long hex head bolts can be used. if standard bolts are used, place a flat washer on the bolt before torquing. The bonding surfaces of the containment fittings are pre -sanded when manufactured. Two-piece secondary containment fittings must be joined using a greater amount of adhesive than is necessary for joining bell and spigot joints of product piping. Coat the ID of both halves of the containment fittings completely.
