Description

technical field [0001] The invention relates to the technical field of flange manufacturing, in particular to a butt welding sealing flange and a manufacturing process thereof. Background technique [0002] Flange is also called flange or flange. Flanges are parts that connect pipes and pipes and valves to each other, and are connected to the pipe end. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flanges are divided into threaded (wire) flanges, welding flanges and ferrule flanges. [0003] With the increasing status of wind energy in the energy strategies of various countries, wind power generation has been widely used. Large flanges are one of the important components of wind power equipment. They play a role of connection and support in the overall structure of wind power towers. Their demand has also increased significantly with the development of wind power. There are two main traditional producti...
