Technical details and manufacturing context for Manifold Body

Definition
The manifold body serves as the central structural component of a vacuum manifold system, typically constructed as a rigid housing with multiple ports and internal passages. It functions as the primary framework that supports and connects various vacuum lines, valves, and fittings, ensuring proper vacuum distribution and maintaining system integrity under pressure differentials. Within the vacuum manifold assembly, it provides mounting points for other components and maintains the sealed environment necessary for vacuum operations.
Working Principle
The manifold body operates by providing a sealed, rigid structure with precisely machined internal passages that connect multiple vacuum ports. It maintains vacuum integrity by preventing leaks through its solid construction and proper sealing surfaces, while distributing vacuum pressure evenly to connected lines. The body withstands pressure differentials between atmospheric pressure and vacuum conditions without deformation.

Components / BOM
  • Mounting Flange
    Provides secure attachment points for connecting the manifold body to other system components or supporting structure
    Material: Same as main body material
  • Port Connections
    Precision-machined openings with sealing surfaces for attaching vacuum lines, valves, or instruments
    Material: Same as main body material
  • Internal Passages
    Machined channels within the body that connect various ports and allow vacuum flow distribution
    Material: Same as main body material
Engineering Reasoning
0.001-1.0 bar absolute pressure
0.0001 bar absolute pressure (10 Pa) differential across wall thickness
Design Rationale: Buckling instability due to external atmospheric pressure exceeding Euler critical load at 0.0001 bar internal pressure differential
Risk Mitigation (FMEA)
Trigger Thermal cycling between 293K and 473K at 5K/min rate
Mode: Low-cycle fatigue crack initiation at weld joints
Strategy: Integral forged construction with controlled cooling rate <2K/min during manufacturing
Trigger Corrosive gas exposure (Cl2 concentration >100 ppm)
Mode: Stress corrosion cracking at 316L stainless steel grain boundaries
Strategy: Electropolished interior surface with Ra<0.4μm and nitrogen purging system
