What is the difference between ERW and CEW pipes?

Electric Resistance Welding(ERW) Pipe is fabricated by moving metal and afterward welding it longitudinally over its length. Consistent pipe is produced by expelling the metal to the coveted length; hence ERW pipe have a welded joint in its cross-segment, while consistent pipe does not have any joint in its cross-segment all through its length.

Welded Tubes are COLD (DRAWN OVER MANDREL) when the application required close dimensional resistances. They are called CEW Tubes or CDW Tubes. These tubes are broadly utilized as a part of vehicle industry and furthermore to manufacture material taking care of gear, exceptional reason machines, water powered hardware, material apparatus, and so forth. Much the same as Seamless Precision Tubes, they too have low carbon content, are very flexible, reasonable for bowing. The tubes are toughened, if required, in the wake of drawing, fixed and experience a pickling procedure that gives it a fantastic loopholes free wrap up.
