When assembled, spacer pushes Bellrelieving stress and reducing chances of tele-scoping pipes. Spacers maintain proper flowline while restraining against INSTALLATION-RESTRAININGThe CASCADE Casing Spacer system replaces the old method of banding wooden skids to the car-rier pipe with steel straps.

3 Compare CASCADE S method with the obsolete one. In addition to the typ-ical positioning design shown on this page, CASCADE has also developed designs for: Placing multiple carriers within one Casing Positioning thermally insulated pipe without damage to insulation Centering small carriers within large casings Positioning gravity sewer to on grade requirementsCASCADE FEATURES Lowest coefficient of friction in the industry easy to push High corrosion resistance eliminate backfill Dielectric insulator cathodic protection Design flexibility position carrier positively Simple to use trouble free insertion Require at least two sets ofhands to attach. Cumbersome, time consum-ing, greasy. Notching andbanding tools needed. Hard to on weldbeads. Carrier rotates. Jointsare destabilized. Binding canbreak straps or skids, makingremoval and reinsertion nec-essary.

5 New chal-lenges are welcome, but chances are if it is awater or sewer application - we ve already done is the leader in quality as well as expe-rience from the liner to the runner - inside to out- there is no corner cutting. Each componentmaterial was carefully selected so that the prod-uct would be top notch - the best make cheaper products - not CASCADE? Casing SPACER PLACEMENT DIAGRAMBASIC POSITIONSTYPICAL PLASTICCARRIERWhen deciding the width and placement inter-vals of CASCADE Spacers , the main concernsare pipe stiffness, joint stability, height of separa-tion between carrier and Casing , and live , stiffer pipe can be supported ade-quately at greater intervals than more flexiblepipe.
