Port Flange/Connection: Temperature Range -20°C to 200°C

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.

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.
