Flange Adapters

admin

here is some stuff i did today, they are what I call flange adapters.  basicly what happend was customer has a alum watter tanker that had some odd ball size flanges on it and since i dont have a tig rig to put in standard flanges i did this took a 4" sch 80 nipple beveled it cut a flange out of 1/2" plate to match the odd ball one then they can bolt that on the truck screw on a standard flange and attach a valve there will be a gasket between the steel flange and aluminum flange.

Reply:Looks like it will work to me! Did you weld inside the flange too? Or just relying on penetration from the outer weld? Not saying you should, just asking questions. Be careful running your pipe vise on the threads like that, maybe a better idea would be to screw a coupler on the threads, then clamp on the coupler. Either way, well done.
