Flanging is formed by turning the outer edge or hole edge of the blank or semi-finished product into a vertical edge along a certain curve. According to the shape of the blank and the edge of the workpiece, flanging can be divided into inner hole (round hole or non-circular hole) flanging , plane outer edge flanging and curved surface flanging, etc. Flanging can replace the deep drawing process of some complex parts, improve the plastic flow of the material to avoid cracking or wrinkling. We can supply carbon steel flanging, alloy flanging, stainless steel flanging Edges etc. These products comply with ASME B16.9, ISO, API, EN, DIN, BS, JIS, GB etc. Application : chemitry industry , oil and gas industry etc.
