How about: It's heavy; this translates to labor and material costs to install, support, seismically brace. It requires special equipment to fabricate and isn't friendly to field mod's like, at all. It requires flanged or mechanical joints, which are expensive and labor intensive. It's more expensive than steel and our industry will organically migrate to the cheapest material choices 99.93% of the time.
I'm sure there are plenty more reasons but it makes very little sense to me ... who's asking you? SL -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Matt Grise Sent: Tuesday, November 25, 2014 6:27 AM To: [email protected] Subject: Ductile Iron Pipe I was asked recently why we (sprinkler people) don’t use DI pipe for above ground systems. My first thought was 1) cost 2) hard to groove/thread 3)not available in small diameters. But I have not really been able to find any info that specifically states a reason. I thought I would check with the forum before I repeated anecdotal info. Thanks!
