Flow Fab Full Jacket

Flow Fab Full Jacket, Oversize Flanges (Type B)
As with oversized flanged piping systems, we weld oversized flanges to the valve (Example: 2" valve with 3" flanges). These jackets give excellent heat coverage with the welded jacket terminating at the back of the flange. Flange face to face dimension is normally that of a valve the size of the oversize flanges (Example: a 2" X 3" valve has the face to face dimension of a 3" valve). These valve jacket types are typically used with jacketed piping. For example, the jacketed pipe may have a 2" core with an exterior 3" jacket pipe that will accommodate 4" flanges.
