Description

Founded in 1991 and built over the years with air and creativity, HGFF GROUP Co., Ltd. is a powerhouse manufacturer, supplier and exporter of Blind Flanges which stand for quality and convenience. 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.
