The 5-inch Blind Flange is a heavy-duty flange used to seal the end of a piping system or pressure vessel opening where no pipe is connected. Blind flanges are solid plates with bolt holes around the perimeter, designed to be bolted between two mating flanges to provide a leak-proof and secure closure. They are essential for blocking the flow in piping networks, allowing for testing, inspection, or future system expansion without the need for caps or plugs.
Blind flanges are manufactured in various materials such as carbon steel, stainless steel, and alloy steel, and are available in different pressure classes (for example, Class 150, 300, 600) and facing types (raised face, flat face, or ring-type joint) to suit diverse industrial needs.
The 5-inch size refers to the nominal pipe size (NPS) that the flange is designed to seal, and it conforms to international standards such as ASME B16.5 for dimensions and pressure ratings.
