Lap Flange

Lap Joint Flanges are used with a stub end, which is welded to the pipe. They are designed to swing over the pipe without the need for welding. Since they do not come in contact with the inner fluid, they do not corrode and can be re-used. Our ANSI B16.5 Stainless Steel Flanges are inexpensive, widely useful, and can be easily assembled and dismantled for quick inspection.
