The most common process pipe joint is the butt weld. The ends of pipe to be welded must have a certain weld preparation called an End Weld Prep (EWP) which is typically at an angle of 37.5 degrees to accommodate the filler weld metal. The most common pipe thread in North America is the National Pipe Thread (NPT) or the Dryseal (NPTF
Perhaps the simplest and cheapest of them all is the Baptist well drilling method, which uses lightweight and cheap PVC pipe for most of the drill stem and in which the drill bit doubles as a foot valve. Wells over 100 metres deep have been drilled this way.
