What is the difference between wrought pipe and cast pipe?
Wrought pipe and tubing is steel formed into a tube and welded down the seam or drawn seamless pipe or tubing. It is used for higher pressure application as well as decorative work. It is normally welded to elbows, etc.
Cast pipe is iron or steel poured into a mold (which may be splitting for centrifugal casting) which hardens in the shape of the mold. Cast is heavier, thicker walled, weaker and cheaper and is not suitable for higher pressures. Cast fittings may be threaded or sealed in other ways.
