Structural Design:

Multiple bolt holes are distributed on the flange, which are used for tight connection with the matching flange.

There is a raised short neck (neck) in the center. The pipeline can be inserted into the neck for welding, enhancing the connection strength and sealing performance.

Surface Markings: Usually, information such as material, pressure rating, and specifications (such as “304” “16MPa” etc.) is engraved on the edge of the flange, facilitating identification and selection.

Main Applications

Pipeline System: Widely used in medium and low-pressure pipeline connections in industries such as petroleum, chemical engineering, water treatment, power, food and medicine.

Equipment Interface: As the inlet and outlet connection flanges for pumps, valves, heat exchangers, etc.

结构设计：

法兰盘上分布多个螺栓孔，用于与配对法兰紧固连接。

中心有一个凸起的短颈（颈部），管道可插入颈部后进行焊接，增强连接强度和密封性。

表面标识：通常在法兰边缘刻有材质、压力等级、规格等信息（如 “304”“16MPa” 等），便于识别和选型。

主要用途

管道系统：广泛应用于石油、化工、水处理、电力、食品医药等行业的中低压管道连接。

设备接口：作为泵、阀门、换热器等设备的进出口连接法兰。
