Ladies/Gentlemen: As designers/specifiers (former fitter/installer), I see no reason to prohibit mechanical tees from (vitually) any commercial project. Our PE/FPE's do not restrict their use and, frankly, they can come in pretty handy at times. If anyone knows of an actual "Code"/NFPA-13 citation, I would sure love to hear it. That said - and engineering "judgement" acknowledged - if the project spec's prohibit MT's - then they cannot be used, in my opinion. They are used on our projects all the time. Also, our inspectors (retired State Fire Marshals) have no 'grievances' against MT's.
"Roust-a-Bout" fittings - now that is a different matter. Are they still used?? Regards to all, Jerry [email protected] Jerry D. Watts, SFPE President & Co-Founder ACCENT FIRE ENGINEERING INT'L.
