End Flanges: Diameter Range 200-800 mm, Thickness 25-60 mm

Component Specifications

Definition

End flanges are precision-machined circular components installed at both ends of a pressing cage barrel to provide structural integrity, pressure containment, and sealing functions. They serve as mounting interfaces for adjacent components while maintaining alignment and preventing material leakage during high-pressure operations.

Working Principle

End flanges function by distributing axial and radial loads across the barrel structure through their bolted connections, creating a sealed pressure boundary that contains processed materials within the pressing chamber. They transfer mechanical forces while maintaining precise dimensional tolerances for operational reliability.

Materials

Typically manufactured from forged or cast carbon steel (AISI 1045/4140), stainless steel (316/304), or alloy steel with hardness ratings of 25-35 HRC. Surface treatments include zinc plating, powder coating, or passivation for corrosion resistance.
