Also known as Schedule 40 pipe stub ends, these have thicker walls than our thin-wall stainless steel unthreaded butt-weld pipe stub ends. They have beveled ends that, when flush to pipe, create a trough for a strong weld that permits maximum flow.

Pipe stub ends are used with flanges. Slide a flange onto the stub end and weld the stub end to pipe (not the flange). Since the flange isn’t welded to the pipe, it can be disconnected easily, which creates an access point for frequent cleaning and inspecting.
