Structural features of the elongated necked flange 📌

Elongated neck: Compared to standard flanges, the neck is significantly longer, which enhances the connection strength between the flange and the pipeline, especially suitable for high-pressure or situations with large temperature fluctuations.

Flange disc: The structure is similar to a regular flange, with multiple holes on the disc for connecting other flanges or pipeline components via bolts.

Sealing surface: Various sealing designs such as flat sealing and convex sealing are adopted to ensure no leakage at the connection point.

Strengthening design: The elongated neck structure increases the overall strength of the flange, enabling it to withstand greater pressure and mechanical loads.

长高颈法兰的结构特点 📌

长颈部：相比标准法兰，颈部明显更长，可增强法兰与管道的连接强度，尤其适用于高压或温度波动大的工况。

法兰盘：结构类似普通法兰，盘上设有多个孔位，用于通过螺栓连接其他法兰或管道组件。

密封面：采用平面密封、凸面密封等多种密封设计，确保连接部位无泄漏。

加强设计：长颈结构提升了法兰整体强度，使其可承受更大压力与机械负荷。
