A105 Raised Face Blind Flange

Selected A105 Raised Face Blind Flange 02 -26'' #600 A105 Raised Face Blind Flange
A105 Raised Face Blind Flange 02 -26'' #600 A105 Raised Face Blind Flange

The A105 Raised Face Blind Flange is a vital component in piping systems, designed to seal off the end of a pipeline or vessel, preventing the flow of fluids while providing easy access for inspection and maintenance. Manufactured in accordance with ASME B16.5 specifications, this blind flange is crafted from carbon steel, ensuring corrosion resistance and the ability to withstand high pressures and temperatures. The raised face design enhances the sealing capability by increasing the contact area with the gasket, ensuring a secure seal.

Governing Standards

ASTM A105 Covers forged carbon steel piping components for ambient- and higher-temperature service in pressure  systems. Included are flanges, fittings, Valves, and similar parts ordered  either to dimensions specified by the purchaser or to dimensional standards.
ASME   B16.11 Covers ratings, dimensions, tolerances, marking and material requirements for socket-welding and threaded  forged fittings. These fittings are designated as Class 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings.
