High-raise flanges are primarily used in stringent operating conditions. What sets high-raise flanges apart from other flanges is that there is a long and sloping high neck from the焊接 joint between the flange and the pipe to the flange disk. This section of the high neck has a wall thickness that gradually transitions to the thickness of the pipe wall in the height direction, improving the discontinuity of stress, thereby enhancing the strength of the high-raise flange.

High-Radius Flanges are used to connect two pipes or fittings by first securing each to a flange disk. A flange gasket is then inserted between the two disks, which are then bolted together. Some fittings and equipment come with a built-in flange disk, also considered a flange connection. High-radius flanges can be categorized by material, including stainless steel, carbon steel, alloy steel, and special steel high-radius flanges, among others. High-radius flange connections are an important method in pipeline construction, offering ease of use and the ability to withstand high pressures. They are widely used in industrial pipelines. High-radius flanges are extensively applied in various fields such as food, oil, petrochemicals, mechanical manufacturing, wastewater treatment, and aerospace.
