Product Description
ASTM A182 Stainless Steel 304L / UNS S30403 / 1.4306 Blind RF Flange
ASTM A182 F304L stainless steel Blind Flange is a solid disk used to seal the end of a pipe or a vessel, preventing the flow of material through the pipe. It’s called “blind” because it has no bore or hole in the center. For more information, please refer to the below:
- Design: It has a circular plate shape and can come in different pressure ratings (e.g., 150, 300, 600, etc.).
- Dimensions: Available in various sizes, typically following standardized dimensions as per ASME, DIN, or other relevant codes.
- Thickness: Varies depending on the pressure class and size, with thicker designs for higher pressure applications.
- Bolt Holes: Usually have bolt holes for securing the flange to the pipe or vessel.
- Function: 1>. Sealing Purpose: Used to block the flow of liquids, gases, or any process medium in pipelines. 2>. Pressure Containment: It helps maintain the pressure within the system, acting as a barrier. 3>. Inspection/Modification: Often used in situations where a system might need to be closed temporarily and then opened again in the future, such as during maintenance or inspection.

Advantages of A182 F304L Blind Flange
- Corrosion Resistance: Offers good resistance to a wide range of chemicals, making it suitable for aggressive environments.
- Durability: It is resistant to oxidation and scaling at high temperatures, ensuring a long service life.
- Weldability: The lower carbon content of F304L stainless steel improves its weldability, reducing the risk of sensitization (formation of chromium carbides that weaken the material).
- Ease of Fabrication: It can be easily fabricated and formed for use in various industries.
Application
-
Chemical Processing Plants: Due to its corrosion resistance, A182 F304L is widely used in chemical processing and handling of aggressive media.
- Food and Beverage Industry: Stainless steel’s non-reactivity and ease of cleaning make it ideal for food and beverage processing systems.
- Oil and Gas Industry: It’s used in pipelines for isolating sections of the pipeline or vessel.
- Pharmaceutical Manufacturing: Cleanliness and resistance to contamination make it a popular choice in pharmaceutical and biotechnology applications.
