Port Body / Flange: Temperature Range -40°C to 400°C

Component Specifications

Definition

A port body/flange is a critical industrial engineering component designed to create a secure, leak-proof connection point for pressure and vacuum systems. It serves as the structural interface between piping/tubing and equipment, featuring precisely machined surfaces for gasket sealing, bolt patterns for mechanical fastening, and standardized port dimensions for fluid compatibility. This component ensures proper alignment, maintains system integrity under varying pressure conditions, and facilitates maintenance access while preventing contamination ingress.

Working Principle

The port body/flange operates on mechanical sealing principles where a compressed gasket creates a barrier between mating surfaces. When bolted to a corresponding flange, it forms a pressure-tight joint through surface contact pressure distribution. The component maintains system integrity by withstanding axial and radial forces while providing a standardized interface for fluid transfer under positive or negative pressure conditions.

Materials

Stainless steel (AISI 304/316), carbon steel (ASTM A105), aluminum alloys (6061-T6), brass (C36000), or engineered plastics (PTFE, PEEK) depending on application requirements. Materials selected based on corrosion resistance, pressure rating, temperature range, and fluid compatibility.

Frequently Asked Questions

What is the difference between port body and flange in industrial applications?

Port body refers to the integrated component with threaded or welded connections, while flange specifically denotes the flat, boltable interface surface. In combined 'port body/flange' components, these features are integrated into a single unit.

How do I select the right gasket for a port body/flange?

Gasket selection depends on pressure rating, temperature, fluid media, and flange face type. Common choices include spiral wound, ring joint, or flat gaskets matching the flange specifications and material compatibility.
