Stainless steel 304 blind flange

What is stainless steel 304 blind flange?

A stainless steel 304 blind flange is a type of flange made from stainless steel grade 304, which is a commonly used austenitic stainless steel alloy. The blind flange is a solid disk with bolt holes that is used to close off the ends of a piping system or a vessel. It is called a "blind" flange because it does not have a center opening like other types of flanges.

Characteristics and features of a stainless steel 304 blind flange:

1. Material: Stainless steel 304 is a versatile and corrosion-resistant alloy that contains a combination of chromium and nickel. It provides good strength, excellent resistance to oxidation, and is suitable for a wide range of applications.

2. Size and Dimensions: Blind flanges are available in various sizes and dimensions to suit different piping system requirements. The flange size is determined by the pipe size it will be used with.

3. Design and Construction: A blind flange is typically flat-faced, meaning that the sealing surface is flat and does not have a raised gasket contact surface. It has bolt holes around the periphery for fastening it to the mating flange or equipment.

4. Application: Blind flanges are commonly used in piping systems, pressure vessels, and equipment where the end of a pipe needs to be closed off permanently or temporarily. They provide a means for future connections or inspections and prevent the flow of fluids or gases.

5. Corrosion Resistance: Stainless steel 304 offers good resistance to corrosion, making it suitable for various environments, including chemical processing, oil and gas, water treatment, and food processing industries.

6. Standards and Certifications: Blind flanges, including stainless steel 304 blind flanges, are manufactured according to industry standards such as ASME B16.5 and ASME B16.47. It is essential to ensure that the flange meets the required standards and has the necessary certifications for the intended application.

When selecting a stainless steel 304 blind flange, it is important to consider factors such as pressure rating, temperature, compatibility with the fluids or gases being conveyed, and the specific requirements of the piping system or equipment.
