Pipe-Working Machine
a machine for working metal (mainly steel) pipes by chip removal or threading. Pipe-working machines are of three main types. Cutting machines are used to obtain accurate end surfaces. Pipe-threading and pipe-roll-threading machines are used to obtain cylindrical and tapered threads; the roll-threading method usually provides a stronger threaded joint. In the manufacture of pipes and tubing for critical applications, special machines are used to remove the imperfect external layer of pipes prior to cold rolling. Want to thank TFD for its existence?
