Blind Flange

   Stainless steel blind flange is a connection form that uses flanges in fields such as fluid, industry, and pipelines. The biggest difference between stainless steel blind flange and a regular flange is that there is no inner hole in the middle.

   One of the functions of stainless steel blind flange is to block one end of the pipeline. At the same time, in the later cleaning of pipeline debris, stainless steel blind flange is more flexible than pipe cap because stainless steel blind flange is fixed with bolts and nuts and can be disassembled as needed, while pipe cap is directly welded on. To clean the pipeline, caps can only be cut off. Compared to other stainless steel flanges, it is also easier to disassemble and replace.

   There are many materials for blind flange, including stainless steel, alloy steel, carbon steel, etc. Stainless steel blind flange has better durability compared to carbon steel blind flange, and is much cheaper than alloy steel blind flange, which can save costs. At the same time, for systems that require complete isolation, stainless steel blind flange is also a reliable isolation method. Therefore, stainless steel blind flange is the first choice for many pipeline manufacturers.

   Its main standards include ASME B16.5（CLASS 150/300/600/900/1500/2500）、ASME B16.47、EN 1092-1（PN6/10/16/25/40/63/100)、 DIN 2527 DIN 2543、DIN 2545、DIN 2566、DIN 2572、DIN 2573、DIN 2576、DIN 2631、DIN 2632、DIN 2633、DIN 2634、DIN 2638、JIS B 2220、KS-1503 and so on，and the sealing surface of stainless steel blind flange Raise Face、Flat Face.
