Blind Flange Stainless Steel Flange

A stainless steel blind flange is a type of flange that is made entirely from stainless steel. It is used to seal the end of a pipe or vessel

in order to prevent the flow of fluid or gas.Stainless steel blind flanges are commonly used in applications where corrosion resistance is crucial.

Stainless steel is known for its excellent resistance to corrosion, making it ideal for use in industries such as oil and gas, chemical processing,

water treatment, food processing, and more.There are different grades and types of stainless steel blind flanges available, each with its own unique

properties and suitability for specific applications. Some common types include:Stainless Steel 304 Blind Flange: This is the most commonly used

stainless steel grade that provides good corrosion resistance and is suitable for general-purpose applications.Stainless Steel 316 Blind Flange:

This grade offers better corrosion resistance than 304 stainless steel and is particularly suitable for applications where the flange will be exposed

to harsh environments, such as high chloride levels or acidic conditions.Stainless Steel 316L Blind Flange: Similar to 316 stainless steel,

316L is a low-carbon variant that offers improved corrosion resistance and greater resistance to sensitization.

Stainless Steel 904L Blind Flange: This highly corrosion-resistant grade is used in extreme environments,

such as in the chemical and petrochemical industries, where resistance to acids, chlorides, and other corrosive substances is critical.

Stainless steel blind flanges are available in various sizes, pressure ratings, and flange face types, such as raised face (RF) or flat face (FF).

It is important to choose the appropriate size, pressure rating, and material grade that suits your specific application requirements.

A105 Carbon Steel Flanges

A105 carbon steel flanges are commonly used in piping systems and equipment in industries such as oil and gas, petrochemical, and power generation.

These flanges are made from ASTM A105 carbon steel, which is a forged carbon steel with great strength and durability.A105 carbon steel flanges are available

in various types, such as slip-on flanges, weld neck flanges, blind flanges, threaded flanges, and socket weld flanges. They come in different sizes ranging from

1/2″ to 48″ and are typically rated for different pressure classes, such as 150, 300, 600, 900, 1500, and 2500.These flanges have a raised face or flat face configuration,

depending on the sealing requirements of the application. They are used to connect pipe sections or valves together, providing a secure and leak-free connection.

The carbon steel construction makes them suitable for high-temperature and high-pressure applications.
