Tubing Pipe is a pipe or hollow cylinder for the conveyance of fluids (liquids or gases). The terms 'pipe' and 'tubing' are almost interchangeable, although minor distinctions exist (generally, "tubing" implies tighter engineering requirements than "pipe"). Both "pipe" and "tube" imply a level of rigidity and permanence, whereas a "hose" is usually portable and flexible.
