Steel Worlds Industries

Key Features:

Tapered Hub: The flange has a long, tapered neck that is welded to the pipe, creating a strong and smooth transition from the pipe to the flange.
High Strength: Designed to withstand high-pressure and high-temperature applications due to the robust weld joint and the continuous reinforcement provided by the tapered neck.
Versatile Materials: Available in materials such as carbon steel, stainless steel, alloy steel, and various grades of high-strength alloys, making them suitable for a wide range of applications.

Common Types:

Long Weld Neck Flange: Features a longer neck compared to the standard weld neck flange. It is used in applications where additional reinforcement and support are needed.
Short Weld Neck Flange: Has a shorter neck and is used where space is limited but strong, reliable connections are still required.
Blind Weld Neck Flange: A type of weld neck flange without a bore. Used to seal the end of a pipe or vessel.

Standards and Specifications:

ANSI/ASME B16.5: Standard for pipe flanges and flanged fittings, including weld neck flanges, specifying dimensions and tolerances.
ASTM A105: Specification for carbon steel forgings 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.
