DIN Blind Flanges for sale A blind flange is a solid plate or a common steel plate used to block pipeline equipment at the connection between two flanges. The purpose is to test the pressure, leak, and block the pipeline of the pipeline equipment.
Product pipe sizes range from 陆" to 96" and flange ratings range from 150# to 10,000#. Blind flanged products utilize raised or annular tongue and groove engagement gasket surfaces. Blind flanged products are available in A (MSS SP44) or B (API 605) series and comply with ASME/ANSI B16.5 and B16.47 specifications.
The production process is mainly divided into four types: forging, casting, cutting and rolling.
FAQ
Do blind flanges have raised faces?
Blind flanges, like standard pipe flanges, can be raised face (RF) or flat face (FF). If the flange is RF, we recommend using a standard ring gasket suitable for service and/or testing.
Why use raised face flanges?
The raised surface is designed to reduce the surface area of the seal, thereby concentrating the surface pressure exerted by the flange mating. The result is a stronger seal. The convex surface has a machined serrated surface that bites into the washer whenever pressure is applied.DIN Blind Flanges for sale
