Main features of blind flanges 💡

Sealing function: The core role is to close the opening of a pipeline or equipment, prevent liquid or gas leakage, and achieve isolation.

Structure: Usually in a circular disc shape, with no hole in the center or a closed hole. The appearance is similar to a regular flange, but the middle part is a completely sealed surface.

Materials: Common materials include stainless steel, carbon steel, alloy steel, cast steel, etc. Selection depends on the application environment and medium characteristics.

Dimensions: Various sizes are available, determined based on pipeline diameter, pressure grade, and usage environment. Refer to ANSI, DIN, JIS, etc. standards.

Installation method: Generally fixed with bolts. During installation, it needs to be precisely matched with the pipeline end.

盲法兰的主要特点 💡

封闭功能：核心作用是封闭管道或设备的开口，阻断液体或气体泄漏，实现隔离。

结构：通常为圆形盘状，中央无孔或为封闭孔，外形与普通法兰类似，但中间为完全封闭面。

材料：常见材料包括不锈钢、碳钢、合金钢、铸钢等，需根据应用环境和介质特性选择。

尺寸：尺寸多样，依据管道直径、压力等级和使用环境确定，可参考 ANSI、DIN、JIS 等标准。

安装方式：一般采用螺栓固定，安装时需与管道端口精准匹配。
