2” xfr pipe firestopping system in concrete wall
Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs. We have a few systems for a maximum 2" diameter XFR plastic pipe with a concrete wall. A common one we reference is cUL C-AJ-2900 for a sealant only solution. If you have a over 2" diameter pipe, there's cUL C-AJ-2035, cUL C-AJ-2053 and cUL C-AJ-2678 with either of them using wrap strip retaining collar or Hilti CP 643 Firestop Collar as the firestopping method.
Additionally, 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, including the Hilti Firestop Selector. The Firestop Selector is an intuitive search function that allows you to search through existing systems to find one that works for you.
You can find more information on how to access this new platform online here: hilti.com/ej (US) or 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.)
If you would like to download the mobile version of the Hilti Firestop Selector, you can do so on the Google Play Store or Apple Store.
Thank you,
