This is not quite sprinkler related but it's dealing with a fire pump and metric versus imperial units.
I have a pump installed by a Turkish contractor. We're revamping the pump piping to conform as good as we can to NFPA. Well we tried to bolt our OS&Y valve up to their pump and the bolt circle is a little smaller then ours. Our valves as all from the USA and that's what the client wants. So now I'm faced with boring out the holes or something to make them match up. The flange has a PN16 which is less than a 150 class flange, which would be roughly PN20. Besides machine drilling the holes, anyone run into this before? We have groove flange adapters that will accommodate the PN16 flange. Just means we'll have to add in a little piece of pipe and order more groove flange adapters from the states. Thanks! _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
