UNS R50400 Gr. 2 DIN 3.7035 Forged titanium fange blind flange BL
F2 150# 300# 600#
BL flange is also know as blind flange. It's a connection form of
flange. It's actually a flange without a hole in the middle. One of
its functions is to block the end of the pipeline, and the other is
to facilitate the removal of debris in the pipeline during
maintenance. As far as the blocking effect is concerned, it has the
same effect as cap and plug. But there is no way to disassemble the
plug, while the bind flange is fixed with bolts, which is very
convenient to disassemble.
