Main Inlet Port

Primary entry point for gas flow into injection manifold systems

Component Specifications

Definition
The Main Inlet Port is a critical fluid handling component designed as the primary entry interface for gas streams into gas injection manifold systems. It serves as the initial connection point where external gas supply lines interface with the manifold distribution network, featuring precision-engineered geometry to ensure laminar flow transition, minimal pressure drop, and secure sealing under operational conditions. This component typically incorporates standardized flange or threaded connections, flow conditioning features, and robust structural design to withstand system pressures while maintaining gas purity and distribution accuracy.
Working Principle
Operates as the primary gas entry interface where external supply lines connect to the manifold. It facilitates controlled gas admission by maintaining pressure integrity through precision sealing surfaces, while its internal geometry (often featuring tapered or venturi-like profiles) conditions incoming flow to reduce turbulence and pressure fluctuations before distribution to downstream injection points. The port's design ensures uniform gas distribution by minimizing flow resistance and preventing backflow through integrated check valves or directional flow features.
Materials
Stainless Steel 316L (ASTM A240), Aluminum 6061-T6 (for non-corrosive gases), or Nickel Alloy (for high-temperature/high-corrosion applications). Surface finish: Ra ≤ 0.8 μm for sealing surfaces. Optional coatings: PTFE for chemical resistance, ceramic for abrasion resistance.
Technical Parameters
  • Leak Rate < 1×10⁻⁹ mbar·L/s (helium leak tested)
  • Flow Capacity 10-500 SCFM (standard configurations)
  • Port Diameter 0.5" to 3" (standard sizes)

  • Temperature Range -40°C to 200°C (standard), up to 400°C (high-temp variants)
Standards
ISO 5211, DIN 3852, ASME B16.5, ISO 1179

Frequently Asked Questions

What is the difference between Main Inlet Port and standard pipe fittings?

Main Inlet Ports are specifically engineered for gas injection manifolds with features like flow conditioning geometry, precision sealing surfaces, and compatibility with manifold mounting patterns, whereas standard fittings are generic connectors without optimized flow characteristics.

Can Main Inlet Ports handle liquid media?

While primarily designed for gas applications, some variants with appropriate material selection and sealing can handle liquids, but flow characteristics may differ - consult manufacturer specifications for liquid compatibility.

How often should Main Inlet Port seals be replaced?

Seal replacement intervals depend on operating conditions: typically 12-24 months for continuous service, or based on maintenance schedules when leak rates exceed 5×10⁻⁸ mbar·L/s.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
