repairs to be made. A secondary <br />containment sleeve coupling should <br />be used to make this type of repair. <br />Containment sleeve couplings are 14 <br />inches (350mm) long; therefore, do <br />not remove more than 7 inches <br />0 75mm) of containment pipe. <br />Caution: When cutting out extensive <br />damage in the containment pipe <br />(only), be extremely careful not to <br />damage the internal product piping. <br />1. After cutting free the damaged <br />section of containment pipe (no <br />more than 7 inches/175mm long), <br />slit the section of pipe in half and <br />remove. <br />2. Using a sander, coarse file, or 30- <br />40 grit emery cloth, remove sur- <br />face gloss from both ends of the <br />pipe. Sanded area must be a mini- <br />mum of 3 inches (75mm) in length. <br />If contaminated, clean the sanded <br />surfaces with solvent. <br />3. Mix the adhesive with filler.
