We go the extra mile to usher the best services to our customers. Our Stainless Steel Blind Flanges are mostly used to seal the end or opening of a pipe, which is why they come without a bore. This comes in handy for inspection and pressure tests, as it allows quick access to the pipe. We offer ANSI B16.5 Blind Flanges to the high h pressure application industries in numerous thread types and hub requirements as well as in hard-to-nd metals categories like Monel, Hastelloy, Titanium, Inconel, etc.
