SS 420 Lap Joint Flanges

The SS 420 Lap Joint Flange is a unique forging component designed to be used in conjunction with a Stub End (a type of pipe fitting). The flange itself is loose and can be rotated around the stub end, allowing for exceptionally easy bolt hole alignment, which significantly speeds up installation and disassembly, especially in applications involving large diameter pipes or complex layouts. The material, Martensitic Grade 420 Stainless Steel, is chosen for its superior hardness and resistance to wear. Since the fluid only contacts the SS 420 Stub End, the flange material is primarily required for strength, which is efficiently provided by the forging process. Zeron Fasteners manufactures these flanges to stringent specifications, ensuring high material density and structural integrity. SS 420 Lap Joint Flanges are widely employed in systems that require frequent dismantling for inspection or maintenance, such as in food processing, pharmaceutical, and other processes involving sanitary piping or expensive alloy liners.
