Stainless Steel Blind Flange Supplier
A Stainless Steel Blind Flange is a type of pipe flange used in piping systems and is made from stainless steel. Flanges are important components in pipelines and industrial systems, as they provide a means to connect, terminate, or close off the flow of fluids or gases within a system. A blind flange, in particular, is used to seal the end of a pipe or valve.
Here are some key characteristics and uses of stainless steel blind flanges:
Material: Stainless steel is chosen for its corrosion resistance, durability, and strength, making it suitable for various applications, including those in corrosive or high-temperature environments.
Function: An SS blind flange is typically used to seal the end of a pipeline, a valve, or any other equipment that requires a closure. It is not designed to allow the flow of fluid or gas, as it lacks an opening or bore.
Facing: The flange’s facing (the part that comes into contact with the gasket and another flange) can have different surface finishes, such as SS Blind Neck Raised Face Flange (SS BNRF Flange) or SS Blind Neck Flat Face Flange (SS BNFF Flange), depending on the sealing requirements of the specific application.

Installation: Blind flanges are usually installed by bolting them onto the end of a pipe or equipment, providing a strong and leak-tight seal. They are commonly used in situations where future access to the pipeline or equipment may be required.
Applications: ASTM A182 Stainless steel blind flanges are used in various industries, including petrochemical, chemical, food processing, pharmaceuticals, water treatment, and many others. They are employed in both low-pressure and high-pressure systems, depending on the specific design and pressure ratings of the flange.
Pressure Ratings: SS blind flanges are available in different pressure classes to accommodate various system requirements. The pressure class is typically marked on the flange to ensure it is used within its designed pressure range.
Sizes: These flanges come in a range of sizes, from small diameters to very large ones, to fit the corresponding pipes or equipment they will be attached to.
Stainless steel blind flanges offer excellent resistance to corrosion and provide a long-lasting and reliable sealing solution for various industrial applications. When selecting a blind flange for a specific application, it is essential to consider factors such as the material type, pressure rating, size, facing type, and the conditions in which it will be used to ensure a secure and leak-free connection.Specification For SS Blind Flanges
