Drain Outlet Flange: Temperature Range -20°C to +150°C

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.

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.
