High Hub Blind Flange is generally used to close ends of a pipeline system. It's a type of a round plate without a center hold, although these flanges are produced with all the proper bolt holes.
High Hub Blind Flanges are a specific type of flange used in piping systems and connections. Like other flanges, their primary purpose is to connect pipes, valves, pumps, and other equipment to form a piping system. High Hub Blind Flanges, however, have distinct characteristics that make them suitable for particular applications.

Definition: A High Hub Blind Flange is a solid disk with a raised section in the center, known as the hub, and without any bore or opening in the center. The raised hub adds thickness and strength to the flange, making it suitable for high-pressure applications.
Purpose: The primary purpose of High Hub Blind Flanges is to block off a section of a piping system or a vessel, providing a closure for the end of a pipe. Unlike other flanges, they do not have a bore, which means they completely seal the end of the pipe, preventing the flow of fluids or gases.
Key Features: Raised Hub: The elevated center, or hub, of the flange adds extra material and strength, making it suitable for high-pressure applications.
No Bore: Unlike other types of flanges, High Hub Blind Flanges do not have a central opening, providing complete closure to the pipe.
Materials: High Hub Blind Flanges are typically made from materials that provide high strength and corrosion resistance. Common materials include carbon steel, stainless steel, and alloy steel.
Applications: These flanges are used in applications where a solid closure is needed at the end of a pipeline or vessel. They are commonly employed in high-pressure and high-temperature systems, such as in the oil and gas industry, petrochemical plants, and power generation facilities.
Standards: High Hub Blind Flanges are manufactured according to industry standards such as ASME (American Society of Mechanical Engineers) and ANSI (American National Standards Institute) standards. These standards ensure that the flanges meet specific dimensional and material requirements.
Conclusion: High Hub Blind Flanges play a crucial role in piping systems where a secure and sealed closure is necessary. Their design, with a raised hub and absence of a central bore, makes them suitable for applications involving high pressures and challenging environmental conditions. Understanding the specifications and standards associated with these flanges is essential for ensuring their proper selection and installation in various industrial settings.

What is a High Hub Blind Flange?
High Hub Blind Flanges are commonly used to close the ends of a pipeline system. It is a form of circular plate without a centre hold, although these flanges are manufactured with all of the necessary bolt holes. It is used to provide positive pressure near the terminals of pipes, faucets, and equipment nozzles. High Hub Blind Flanges are supplied with NPT Pipe Fittings, which allow for pressure test connections to be made. They are used to blank off the pipe's terminus. They are also utilised to seal off the ends of faucets and pressure vessel openings. When considering internal pressure and high hub blind flanges, bolt weight, particularly in bigger diameters, is the most heavily strained of all types of flanges. Because the maximum stress in a high hub flange is bending stress at the centre, they can be more advanced than other types of steel flanges without risk. High hub blind flanges are designed to suit standard pipe of all sizes.
