Component Specifications

Definition
The Drain Outlet Flange is a precision-engineered mechanical component that provides a secure, sealed interface between a drainage tray's outlet and external piping systems. It features standardized bolt patterns and sealing surfaces to prevent leaks, facilitate maintenance, and ensure proper alignment for efficient fluid discharge in industrial applications.
Working Principle
Creates a pressure-tight mechanical joint using bolt compression to force sealing surfaces (gaskets or machined faces) together, preventing fluid leakage while allowing controlled directional flow from the drainage system.
Materials
Stainless steel (AISI 304/316), carbon steel with corrosion-resistant coating, or engineered polymers (PP, PVC) depending on chemical compatibility requirements.
Technical Parameters
  • Flange Type Slip-on or Weld Neck
  • Surface Finish Ra ≤ 3.2 μm for sealing surfaces
  • Pressure Rating PN10 to PN16
  • Nominal Diameter DN25 to DN150
  • Temperature Range -20°C to +150°C
  • Bolt Circle Diameter Standardized per DIN/ISO
Standards
ISO 7005-1, DIN 2501, ASME B16.5

Frequently Asked Questions

What gasket material is recommended for chemical drainage applications?

PTFE or EPDM gaskets are recommended for chemical resistance; material selection depends on specific fluid pH, temperature, and chemical composition.

How often should drain outlet flanges be inspected?

Visual inspection every 3 months, torque check every 6 months, and complete disassembly inspection annually or per maintenance schedule.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
