The low-pressure small diameter has a wire flange, and the high-pressure and low-pressure large diameter use butt welding flanges. The thickness of the flanges and the diameter and number of connecting bolts are different for different pressures. Different high-pressure flange connection forms are determined according to the specific situation. The required parts and equipment are different, and the procedures and processes required during installation are also different. Therefore, the specific installation components and equipment are determined according to the situation at that time. According to different levels of pressure, flange gaskets are also available in different materials, ranging from low-pressure asbestos gaskets, high-pressure asbestos gaskets to metal gaskets. The large flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used.
High-pressure flanges are mainly used in the installation of pipelines. High-pressure flange connection is an important connection method in pipeline construction. The main connection between pipes and pipes plays an important role and value. The high-pressure flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection.
