The AS 2129 Blank (BLFF) flange is a solid, circular plate flange used to seal the ends of pipelines, valves, or pressure vessels. Designed to meet Australian Standard AS 2129, it is suitable for a variety of pressure ratings and applications. The blank flange, also known as a blind flange, is ideal for isolating sections of piping during maintenance or testing.
Material Specifications:
AS 2129 Blank flanges are manufactured from a range of materials to accommodate diverse operational requirements:
- Carbon Steel: ASTM A105, Grade 250
- Stainless Steel: 304, 316, 316L
- Mild Steel: Common for general-purpose applications
- Alloy Steel: For systems requiring high strength and temperature resistance
- Coating Options: Galvanized or painted finishes for added corrosion protection
Material selection depends on system pressure, temperature, and the type of fluid being transported.
