A blind flange is a solid disk that is used to block off a pipeline or to create a stop. A blind flange has no opening for fluids to pass through. Instead, it is placed in between two open flanges, which stops the flow through a pipe. This type of blockade is used when adding another line onto an existing pipeline or when a new valve is being added. These Blind flanges are manufactured in various national and international standards such as ASTM, ASME, DIN, NFA, JIS, IBR. Our Blind flanges have good corrosion resistance and strength. Our Blind flanges are available in various materials like stainless steel, carbon steel, alloy steel, inconel, incoloy, monel, hastelloy, nickel alloy, copper nickel, etc.
