CFS-CID MD Sleeves - T Rating

CFS-CID MD Sleeves - T Rating

Afternoon,

We installed firestop cast-in devices for metal decks (CFS-CID MD) sleeve in our building for new construction. The piping material for the system is mainly chem PVC. Is there something we could use in conjunction to this sleeve for us to obtain a 2hr. T-Rating? We are having some thigh clearances on the top side of the concrete deck and may not be able to wrap the pipes to meet another manufacturers detail we have.

Hello,
If you have a 4-1/2" floor, you should have a T-rating per System F-A-2313. If your floor is thinner, we'll have to evaluate it and see what solutions we can provide through an Engineering Judgement (EJ) request. I've provided more information on where to submit a request below.

We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)
Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or a Question anytime, anywhere. You can download the app using the appropriate link below.
Hilti Firestop Selector App – Google Play Store

Michael, Are you able to provide some clarification on the piping material? Is the detail stating that CPVC piping max 4inch diameter must be SDR 13.5 and can only be used for a closed piping system? We have CPVC pipe - open system that is smaller than 4inch max, do we just follow the table below for the T-rating? or since we have an open system we do not achieve the t-rating?
