[0002] In pipeline engineering for petroleum, chemical, food, and fluid transportation, flanges are often used to connect pipes, valves, and pressure vessels. Reliable flange sealing is the most basic requirement for flange connections. However, in actual pipeline engineering, flanges often experience sealing failure and leakage. For flanges used for extended periods, various operating environments, such as high pressure, high temperature, chemical corrosion, and electro-corrosion, can easily lead to sealing failure. Flange sealing surface processing machines are mainly used to repair the sealing surfaces of such flanges. For the repair of sealing surfaces of some small-diameter flanges, hand-cranked flange sealing repair devices are often used. These devices are small, lightweight, and portable, and can effectively process the sealing surfaces of flanges. However, current hand-cranked flange sealing repair devices can only process flat flanges and cannot repair the spherical or conical sealing surfaces of lens gasket flanges. Traditional manual cutting and grinding methods are required, which are inefficient, labor-intensive, prone to uneven grinding, and produce poor results.
