217 <br />• <br />Procedure for installing secondary <br />containment saddles: <br />Refer to Figure 2.6.2 <br />1. Locate saddle on pipe and mark <br />around saddle base. <br />Use a file or rough sandpaper (40 <br />grit or less) to remove all surface <br />gloss from the pipe O.D. where the <br />saddle is to be bonded. Use circu- <br />lar or random pattern during sand- <br />ing to eliminate grooves on the <br />pipe surface. <br />3. After sanding, locate saddle on <br />pipe and mark hole to be cut in <br />pipe. Cut a hole of the same size as <br />the outlet of the saddle using a <br />pilot drill and a fine-tooth circular <br />hole saw. Do not force the cutter <br />or it will unduly fray the edges of <br />the hole. <br />4. All bonding surfaces must be free <br />of contamination. See Section 7, <br />paragraph 2.7.2. <br />5. Apply a heavy coat of adhesive to <br />the O.D. of the pipe, I.D. of the <br />saddle, and the edges of the pipe <br />wall exposed by the hole. <br />6. Place the saddle over the hole and <br />clamp with two hose clamps. <br />Using a large screw driver, hand <br />tighten the clamps alternately un- <br />til secure and adhesive squeezes <br />out all the way around the saddle. <br />This will ensure that the pipe O.D. <br />conforms to the I. D. of the saddle. <br />The clamps may be left on or re- <br />moved after the bond has cured <br />and after the flexible connector is <br />installed in the outlet. <br />NCaution: Product pipe maybe <br />under pressure if the testing has <br />been completed. Do not attempt to <br />install a saddle on the containment <br />pipe if the product piping system has <br />been installed and tested. <br />Q' <br />Y <br />1 G <br />Figure 2.6.2 <br />33 <br />
