Lap Joint Flanges
Lap Joint flanges are commonly produced and stocked in several different materials. They are often called Back Up, Loose Ring or Van Stone Flanges. These flanges are used behind and in conjunction with a Stub End. The lap joint flange floats on the pipe which allows allows for easy bolting.
Lap joint flanges are used predominately with mixed materials, on expansion joints and lined piping systems.
