Blind Flange

We provide an extensive range of high quality Blind Flanges. These products don’t have any bore, and they are commonly used to block/close the end of the piping system. Manufactured with the latest advanced technologies and high quality raw materials, these products are highly durable and resistant to corrosion. We offer product customization and they are available at competitive prices.The reduction can be either threaded or welded based upon the requirements of the client.

Description: A� Blind Flange� is a solid disk used to block off a pipeline or to create a stop. Like a regular flange, it also has mounting holes around the perimeter and the gasket sealing rings machined into the mating surface. The difference is that a� blind flange� has no opening to allow fluid to pass through.�  Specifications: Size: 1-13/16 in ~ 26-3/4 in Working Pressure: 2000PSI, 3000PSI, 5000PSI, 10000PSI, 15000PSI, 20000 PSI Material: AISI 4130(forged)/ SUS316/Inconel 625 / 410 Stainless Steel Face: RTJ, FF, RF

A spectacle blind flange is a type of isolation device used in piping systems. It is a forged steel plate that consists of two interconnected discs: a ring with a hole of the same bore size as the pipeline, and a solid disc. In normal conditions, the spectacle blind is installed in the open position and does not interrupt the flow of the fluid conveyed by the pipeline. To stop the flow, the blind end is rotated into place between the flanges. Spectacle blinds are available in standard sizes up to 24 inches and in forged material grades like ASTM A105 (high-temperature carbon), A350 low-temperature carbon), and various ASTM A182 grades (alloy, stainless steel, duplex). They are typically used in conjunction with flanges, and are available with raised face (RF), flat face (FF), or RTJ faces. Technical Specifications of Spectacle Blind Flange Material: Carbon steel, low-temperature carbon steel, stainless steel Standard: ASME B16.48 Size: Up to 24 inches Face: RF, FF, RTJ Handle: Yes
