C. Adhesive for Containment Piping Use only DS -7014 or DS -7069 adhesive manufactured by Smith Fiberglass Products for installation of Smith Fiberglass Products double-wall secondary containment piping systems. SECTION II PREPARATION AND ASSEMBLY A. Pipe Preparation Cut off factory spigots and couplings as needed. 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 must be machined or thoroughly sanded for a length of at least 33/4". Any surface irregularities must be removed. This is most easily accom- plished by using a Smith Fiberglass Products secondary con- tainment scarfing adapter kit. This kit consists of a special blade (33/4" long), blue blade holder, and 3" & 4" gauges which are required to set the tool. The kit is easily adapted to the 2"-6" Smith Fiberglass Products standard tapering tool.

After positioning the black mark on the gauge under the blade, be sure the blade makes uniform contact with the gauge. Blade Set Linein Gauge Blade O O O Gauge Tool Body Blade Holder Blade Set Line Wide Side of Blade Figure 1 The bolts on the blade holder should now be tightened to secure the blade. The tool is now prepared to remove the gloss from the ends of the containment pipe. After removing the gauge, insert the tool into the pipe to be machined until the blade just touches the end of the pipe. Tool must be rota- ted in a counter -clockwise direction. Advance the tool in approximately 'A" increments after each revolution and con- tinue machining operation until the gloss has been removed for a minimum length of 33/4".
