Flange WN 3/4" S-XXS ASME B16.5 600LB Ring Joint ASTM A 105 NORMALIZED

Flange: A flange is a protruding flat rim or collar used for strength, guiding, or attachment to another object. In piping, flanges are used to connect pipes, valves, pumps, and other equipment.

WN: "WN" stands for Weld Neck, which is a type of flange where the neck (or hub) of the flange is welded to the pipe. This provides a smooth bore and better flow of fluids.

3/4": This refers to the nominal pipe size (NPS) of the flange. In this case, it's 3/4 inch, which denotes the size of the pipe that the flange is intended to be used with.

S-XXS: This likely refers to the wall thickness of the pipe or flange. "S" typically stands for "Standard" wall thickness, while "XXS" stands for "Double Extra Strong" wall thickness, indicating a thicker wall.

ASME B16.5: This is a standard developed by the American Society of Mechanical Engineers (ASME) that covers pipe flanges and flanged fittings. ASME B16.5 specifies dimensions, tolerances, materials, marking, and testing for flanges.

600LB: This denotes the pressure rating of the flange, specifically in pounds per square inch (psi). In this case, it can handle pressures up to 600 pounds per square inch.

Ring Joint: This could refer to the type of gasket surface used on the flange. Ring joint flanges are designed to be used with metal gaskets, which are placed within the flange groove to create a seal.

ASTM A 105 NORMALIZED: ASTM A105 is a standard specification for carbon steel forgings for piping applications. "Normalized" likely refers to a heat treatment process used to refine the grain structure and improve the mechanical properties of the material.

In summary, the description "Flange WN 3/4" S-XXS ASME B16.5 600LB Ring Joint ASTM A 105 NORMALIZED" describes a weld neck flange with a 3/4 inch nominal pipe size, designed for use with pipes with standard to double extra strong wall thicknesses, meeting ASME B16.5 standards, with a pressure rating of 600 pounds per square inch. It features a ring joint gasket surface and is made from normalized ASTM A105 carbon steel.
