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.
Technical Parameters
  • Thickness 25-60 mm
  • Bolt Holes 8-24 holes
  • Diameter Range 200-800 mm
  • Surface Finish Ra 3.2-6.3 μm
  • Pressure Rating Up to 25 MPa
  • Flatness Tolerance 0.1 mm/m
  • Bolt Circle Diameter 180-780 mm
Standards
ISO 5211, DIN 2501, ASME B16.5
