Depending on your wall construction, the separation distance between your “bunkers” and your facility, and the fact that you’re more than likely using ¼” coaxial lines (1/2” OD on the jacket), the simplest thing we’ve found that works well is to use electrical conduit as your sleeve through the block wall. If you use rigid material, it can be threaded on the ends, and the caps will provide the “fire separation” for the future passages. You may want to consider a separation distance of about 2” between the sleeves so that a weld head will fit in to perform the operation.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D'>If you’d like to discuss this further, give me a call.

In our application, the rooms are located outside the perimeter of the cleanroom (currently under construction). One of the rooms will be dedicated to toxic/corrosive process gas cabinets and the other to flammable/pyrophoric cabinets. We require some sort of transition in the concrete walls of the bunkers which would allow for simple future expansion as to number and types (single vs coax) of lines out of each room. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-CA>Many thanks in advance for any insights.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-CA>Regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Vito Logiudice<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-CA>Vito Logiudice P.Eng.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Director of Operations<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>QNC & RAC Nanofabrication Facilities<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-CA>University of Waterloo<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>200 University Avenue West<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Waterloo, ON <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Canada N2L 3G1<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Tel: 1-519-888-4567 ext. 38703<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Fax: 1-519-888-7610<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Cel: 1-519-500-2538<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA>Email: vlogiudi@uwaterloo.ca<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-CA><o:p> </o:p></span></p></div></body></html>
