Main material: The overall material is stainless steel (such as 304, 316L), and the surface has been polished or machined, presenting a metallic luster, with excellent corrosion resistance.

Structural design:

Multiple bolt holes are distributed on the flange disk, used for tight connection with matching flanges or equipment housings.

The central hole is an internal thread, which can be directly screwed into pipes, valves or fittings with external threads.

Surface marking: The edge of the flange is engraved with information such as material, pressure rating, and specifications (such as “304”, “150LB”, etc.), facilitating identification and selection.

主体材质：整体为不锈钢（如 304、316L），表面经过抛光或车削处理，呈现金属光泽，耐腐蚀性能优异。

结构设计：

法兰盘上分布多个螺栓孔，用于与配对法兰或设备壳体紧固连接。

中心孔为内螺纹，可直接与带外螺纹的管道、阀门或管件旋合连接。

表面标识：法兰边缘刻有材质、压力等级、规格等信息（如 “304”“150LB” 等），便于识别和选型。
