METHOD OF PROCESSING THE FLANGE OF A PIPE CONNECTOR, CAPABLE OF FORMING A FLANGE WITHOUT A CUTTING OR WELDING PROCESS BY PROCESSING THE FLANGE OF THE PIPE CONNECTOR

摘要

PURPOSE: A method of processing the flange of a pipe connector is provided to enable a flange to be formed without a cutting or welding process since the flange of the pipe connector is processed.;CONSTITUTION: A method of processing the flange of a pipe connector comprises next steps. A pipe is cut to a desired length(S1). One end of the cut pipe is bent and pressed and thus a flange is formed(S2). The outer shape of the pipe, on which the flange has been formed, is ground in a shape to be processed(S3). The forming step comprises next steps. One end of the pipe forms an arc and is externally bent(S21). The bent surface of one end of the pipe is pressed to make a plane(S22).;COPYRIGHT KIPO 2011
