Component Specifications

Definition
A precision-engineered flange connection designed to interface between a machine's drain/outlet port and a valve assembly. It provides a leak-proof, pressure-resistant seal while allowing for easy installation, maintenance, and valve replacement. The component typically features bolt holes, gasket surfaces, and standardized dimensions to ensure compatibility with industrial valve systems.
Working Principle
Creates a mechanical seal between two mating surfaces (port and valve) through compression, using bolts to apply clamping force that compresses a gasket, preventing fluid leakage while maintaining structural integrity under operational pressures and temperatures.
Materials
Stainless steel (AISI 304/316), carbon steel (ASTM A105), ductile iron (ASTM A536), or engineered polymers (PTFE, PVDF) depending on corrosion resistance, pressure rating, and fluid compatibility requirements.
Technical Parameters
  • Face Type Raised face (RF) or flat face (FF)
  • Surface Finish 125-250 Ra μm
  • Flange Standard ANSI B16.5, DIN EN 1092-1
  • Pressure Rating PN16/PN25 (150/300 psi)
  • Temperature Range -20°C to 200°C
  • Bolt Hole Quantity 4, 8, or 12 holes
  • Bolt Circle Diameter As per flange size
Standards
ISO 7005-1, DIN 2501, ASME B16.5, EN 1092-1

Engineering Analysis

Risks & Mitigation
  • Gasket failure leading to leaks
  • Bolt over-torquing causing flange distortion
  • Corrosion in aggressive environments
  • Misalignment during installation
FMEA Triads
Trigger: Improper gasket selection or installation
Failure: Fluid leakage at flange joint
Mitigation: Use correct gasket material/torque specifications; implement installation procedures with torque sequence control
Trigger: Corrosion due to incompatible material with process fluid
Failure: Flange degradation and potential catastrophic failure
Mitigation: Select corrosion-resistant materials (stainless steel, coatings); implement regular inspection schedules

Frequently Asked Questions

What are the main differences between RF and FF flange faces?

Raised Face (RF) has a raised ring around the bore for higher pressure sealing with gaskets, while Flat Face (FF) provides full surface contact, typically used for lower pressure applications or with full-face gaskets.

How do I select the correct gasket material for a port flange?

Select based on fluid compatibility, temperature, pressure, and flange face type. Common materials include rubber (NBR, EPDM), PTFE, graphite, or metal (spiral wound) gaskets matching the flange specifications.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
