ASTM A182 F304L Stainless Steel Flange ASME B16.5 Forged Blind Flange BLRF

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.
