For those experienced or well-versed in site utilities, what options for underground fire service pipe would you recommend? What is currently regarded as the most common options?
I understand ductile iron, concrete, plastic, copper and stainless steel are all permitted by NFPA 24. Posted anonymously by a member for discussion. Discuss this | Subscribe

Ductile Iron is still very common. You see a lot of C900 PVC used in Arizona. On larger underground projects you are seeing more HDPE being used.

I'd go with the HDPE if you get the choice. It holds up, is flexible and easy to modify for future needs.

The flexibility increases HDPE's robustness under seismic inputs if that is a consideration.

Please check Table - 10..1.1 of NFPA 13, 14 & 24 for list of required piping with product specifications for Underground piping or any pipe with FM Approval for utilising in fire systems as Underground pipes.

Be sure to check the soil for corrosion potential. That alone may drive you to plastic for the majority of the piping. You will need to asphalt paint stainless bolts and poly wrap ductile where you need to use metal pieces, but there is not of pipe type for all conditions. Leave a Reply. |
