A titanium blind flange (BL flange) is a flange which has no bore, and is used to close ends of piping systems. A blind flange also permits easy access to a line once it has been sealed. The blind flanges are sometimes machined to accept a pipe of the nominal size to which reduction is being made. The reduction can be either threaded or welded. 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 plugging effect is concerned, it has the same effect as the head and cap. But the head can not be disassembled, and the blind flange is fixed by bolts, which is very convenient to disassemble. Blind flanges are made of carbon steel, alloy steel, stainless steel, plastic, etc.
