The method of making stainless steel flanges and stainless steel flange process description

Stainless steel flange pipe joint is commonly used in construction. Stainless steel flange have excellent performance, excellent heat resistance and pressure resistance and excellent flexibility, the advantages of its products far more than the plastic tube. Stainless steel flange joint is easy to install, high thermal conductivity, is suitable for the floor heating system. Flange connections have excellent impact strength, can welding and mechanical connection. It is better than the lead, polypropylene and rubber better thermal conductivity. First of all, preheat stainless steel flange and analysis how to processing stainless steel flange. Stainless steel fittings made from steel flange. According to the need for cutting the steel plate, using the UOE forming machine, such as punch rushed into a round shape. Will be split in two, and then welding steel. After suppression, must under the condition of high temperature formed flange. After molding, need flange joint outer diameter and wall thickness. Sandblasting, after finishing, and by removing tin plating layer on the surface of the flange joint inside and outside. Welding groove, both sides have. After inspection, seal, spray paint, after the packaging process, stainless steel flange can be shipment. Compared with other pipes, stainless steel flange pipe has two processes: scratch testing and heat treatment. Other steps are the same. Flange improper handling can lead to some deformation defects and causes. In addition, because after pressing the tip of the usually has a larger diameter, so by molding manner. Due to welding, so the need for non destructive testing. Stainless steel flange after heat treatment, there are many ways to the processing of stainless steel flange. Most of them belong to the processing category. The commonly used method including stamping, forging, rolling, expansion, tensile, bending and composite. Stainless steel flange process description: rolling method: use the roll core will check into the outer periphery of the pipe. Used for rim processing. Rolling method: usually do not use the mandrel. Suitable for thick pipe inner edge. Expansion method: the rubber in the hose, with the upper punch compression, and then stretched out hose makes its shape. Another method is the hydraulic forming, the central part of the hose is full of liquid. Then, the hose expansion into the required shape under liquid pressure. This method is usually used in the manufacture of stainless steel flange. Forging method: use the mould forging machine will push pipe or at the end of the section, electric valves, to reduce the outer diameter. Common die forging machine is rotary, hinged lever and roller. Stainless steel flange, flange is a very general due to the excellent properties of the stainless steel itself, in the aspect of life and corrosion resistance more than the ordinary flange.
