To ensure the specific use value and performance of welding flange, withstand high temperature and pressure. In the volume of the flange industry, or flat welding more, flat products accounted for the total, the production of welding is not flat welded products conveniently. Leng, cold extrusion, heading, such as plastic processing collectively.
General use hangs under operating pressure. Stainless steel is one of the highest strength materials in building metal. The forging of the flat welding flange can be divided into free forging, upsetting, extruding, die forging, closed die forging, closed forging, closed die forging and closed upsetting because of the high utilization rate of the material without the flying edge.
Then make a circle with the roll ring machine. The welding flange in the production and welding strict control of the technical parameters of the former refers to the Takiko part of the medial or lateral convex. In the perfect quality management system makes its impact-resistant function greatly enhanced. The different raw material selection makes its corrosion resistance can meet the special anti-corrosion demand of the different application environment. And the price is cheap do not appear already heated good still heating must use the reference electrode to manipulate. The ion-deposited oxide coloring method is a vacuum evaporation plating of the stainless steel flange workpiece in a vacuum coating machine.
