MS ERW Round Structural Pipes also known as round steel tubes, are a common type of steel section which is made either from hot rolled, cold rolled or pre-galvanized steel strips formed by a continuous set of rolls. The slit strip of steel coil goes through a forming and sizing section in a normal cold forming steel mill. The mill consists of a number of passes through which the sheet is gradually formed by pass bending the steel sheet more on each pass. This is done until the two ends of the steel are pressed together and then welded inline. The strips of carbon steel are heated at the edge and welded together forming into longitudinal welds, without any filler metals. Then, weld tubes are cooled down and processed through sizing rolls into round tubes.
