PO Box 407, Middleburg, PA 17842 877-324-ROWE 570-837-6335 fax [email protected] -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jim Davidson Sent: Friday, February 11, 2011 3:56 PM To: [email protected] Subject: RE: misaligned flanges Tom, Some time ago one of my clients seem to have had a similar problem and he purchased a gasket shim kit from a pipe fabrication house which specialized in welded flange pipe segments. From client the firm had gaskets that were slipped in between standard flat flange gaskets to take up angular flange face misalignment. I cannot remember the name of the firm and my client contact has pasted on to a better place. That is what happens when you gain enough experance. Have a fire safe day.

The system side is 1/8" lower than the street side so something has to spring or the riser shortened and it's 8" s40 threaded into flanges, 40 years old. Pipe stands are what I plan to use, 3/4" rod inside 3/4" pipe with a 10" riser clamp around the wafer check and brackets for 30 degree braces to the wall. They were never lined up right I found when it dropped and it's right below a 4' duct where the valve-check-valve assembly is, so no way to hang from structure. There also is no o-ring (as one might expect), just flat faces to mate to the OS&Y flanges. I was thinking of some RTV sealant as a high tack to hold the gaskets and maybe help seal but I'm still going to have misalignment which is my original quandary. Use really long wrenches on the 3/4" rods? Double gaskets? More hangers will not work. The pipe develops "memory" and springs to that spot. Pipe stands can help, but often there is other stuff in the way. Short of chasing the leak around the flange, gaskets are the only control. Are crush gaskets still available?
