Customized ASTM B16.5 Gr2 Titanium Blind Flange For Chemical Industry
Titanium Blind Flanges
BL flange, also known as blind flange, is a connection form of flange without a hole in the middle. It serves two primary functions: blocking the end of pipelines and facilitating pipeline maintenance by allowing easy removal of debris. While it provides the same blocking effect as caps and plugs, blind flanges offer superior convenience as they are bolted in place for easy disassembly.
