Wide application of butt welding steel flange in pipeline engineering

Views: 0    

In pipeline manufacturing, Steel flanges are mainly used for the link of pipelines. In the pipelines that need to link, Various devices include a flange. deficient-Pressure pipelines can use wire flanges and welding flanges with pressures greater than 4 kg. Add sealing points within the two flanges, immediately after tightening with bolts. Steel flanges of different pressures have different thicknesses and use different bolts. When the water pump and valve are connected to the pipeline, parts of this equipment are also made into corresponding steel flange shapes, also called flange connections.

All connecting parts that are bolted and closed at the periphery of the two planes are generally called "flanges". For example, the connection of ventilation pipe, such parts can be called "flange parts". But this connection is only a part of the equipment, Such as the text between the flange and the pump, It is not easy to call the pump 'flange parts'. Smaller ones such as valves Wait, always be called 'flange parts'.
