定义
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.
工作原理
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.

常见问题

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.
