The alloy steel flange material has great strength, large tangential stress and large plastic deformation during cutting, resulting in large cutting force. In addition, the thermal conductivity of the material is very poor, which causes the cutting temperature to rise, and the high temperature is often concentrated in the narrow area near the cutting edge of the cutting tool, thus speeding up the wear of the cutting tool, which generally contains the high melting point element, the high plasticity, the high cutting temperature, the cutting tool wear faster, the grinding knife and the knife changing frequently, thus affecting the production efficiency and the improvement. The cost of cutting tools is used.
It generally contains high melting point elements, large plastic, high cutting temperature, cutting tool wear faster, grinding knife, changing knife frequently, thus affecting the production efficiency and improve the cost of cutting tools. Flanges are used in pairs. Low pressure pipes can be welded with flanges, and welding flange is more than four kg of pressure. Seal gaskets between the two flanges and fasten them with bolts. Different pressure stainless steel flange thickness is different, they use different bolts.
Pumps and valves, when connected to the pipeline, parts of these equipment and equipment are also made into corresponding flange shape, also known as flange connection. All the connecting parts that are closed at the same time with the bolt connection at the periphery of the two plane are generally called “flanges”, such as the connection of a ventilated pipe, which can be called “flanged parts”.
