Stainless steel flange is a disc-shaped complete machine, which is the most common in pipeline engineering, and flanges are used in pairs. In pipeline engineering, stainless steel flanges are mainly used for locking camlock fittings the connection of pipelines. In the pipelines that need to be connected, a flange plate is installed for various installations. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg. A gasket is added between the two flanges and then fastened with bolts. Stainless steel flanges with different pressures have different thicknesses and different bolts. When the pump and the valve are connected to the pipeline, the parts of these equipment are also made into the corresponding flange shape, also called flange connection. Any connection machine that is bolted at the periphery of the two planes and closed at the same time is individually called "flange", such as the connection of ventilation ducts, this type of machine can be called "flange machine". However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not easy to call the water pump "flange-type complete machine". Smaller ones, such as valves, can be called "flange-type complete machines". 

  Due to the high viscosity of the stainless steel flange material and the poor chip breaking performance, it is easy to cause chips to scratch the workpiece thread or the tap to chip during the tapping process of the stainless steel flange, which affects the processing efficiency and thread quality. In order to extend the service life of the tap and improve the quality of thread processing, the following points should be paid attention to. 

  Design and production of taps:   

1. Choose a better tap material. The addition of special alloying elements in general high-speed tool steel can significantly improve the wear resistance and toughness of the tap.  

2. Reasonably choose the heat treatment method of the tool to coordinate the hardness and toughness of the tap.  

3. Properly increase the tap rake angle. But you should be careful, if the rake angle of the tap is too large, it will easily cause the tap to break and the tapped thread to be polygonal when the tool is retracted.  

4. Coating titanium nitride coating on the thread name of stainless steel camlock fittings the tap can significantly improve the wear resistance, heat resistance and smoothness of the tap.  

5. Properly increase the amount of tap shovel back. But you should be careful, if the amount of shovel back is too large, it is easy to cause chips to be stuffed into the rear corner of the tap when the tool is retracted, and the finish of the tapped thread is not good.
