Ah yeah, manually pressing stainless steel? You'd have the forearms of a teenage boy who just found out about his dick.

Unless you really needed that pressed bellows style shape, just weld a ring on the pipe, or run a bead of weld around the pipe. Then your pipe clamp won't be going anywhere. (And given you need a welder to make this device, easier too)
