Would a system conversion to upright or pendent ESFR be possible with the existing piping and a pump?
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Fletcher, Ron Sent: Thursday, May 08, 2008 11:31 AM To: [email protected] Subject: Exposed unexpanded plastic We have an existing building with Viking large drop heads at .45/2000. Storage is being changed to 18 ft high Group A unexpanded plastic. 40 oz cups nested inside each other, shrink wrapped on four sides, cardboard over the top on pallets on the floor, 32 ft. roof, no racks. We want to add a pump without changing the sprinklers but I can't find any criteria that suits the 32 ft. roof with LD heads. The closest we can come to finding appropriate criteria is 15 heads at 50 psi but it's for a 30 ft. roof. The existing pipe size won't support 1.1/2500 and we are not sure if we could classify the storage array as unstable to get to .6/2500. Is there a way to determine pile stability without a burn test or is test data out there that I haven't found? Ideas appreciated. _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
