Steel Worlds Industries

Key Features:

End Closure: Designed to seal the end of a pipe, vessel, or other equipment, effectively stopping the flow and preventing leaks.
Material Versatility: Available in a wide range of materials such as carbon steel, stainless steel, alloy steel, and various plastics, suitable for different pressure and temperature conditions.
High Strength: Capable of withstanding high pressure and temperature applications, depending on the material and design.

Common Types:

Standard Blind Flange: A flat, solid disc with bolt holes around the perimeter. Used for general applications to seal pipe ends.
Raised Face Blind Flange: Features a raised surface around the bolt holes to provide a better seal and is used in higher pressure applications.
Spectacle Blind Flange: Consists of two connected pieces: a blind flange and a spacer (or spacer ring). The spacer can be replaced with the blind flange to seal the pipe.

Standards and Specifications:

ANSI/ASME B16.5: Standard for pipe flanges and flanged fittings, including blind flanges, specifying dimensions and tolerances.
ASTM A105: Specification for carbon steel forged fittings for piping applications.
ASTM A182: Standard for alloy and stainless steel pipe flanges, fittings, and valves.
ISO 9001: Quality management system standard ensuring consistent manufacturing and quality control.
