Component Specifications

Definition
A precision-engineered component integrated into cryogenic storage vessels that enables safe, controlled transfer of liquefied gases (such as liquid nitrogen, oxygen, or argon) into and out of the vessel while maintaining cryogenic temperatures and preventing contamination or pressure loss.
Working Principle
Utilizes vacuum-insulated or multi-layer insulated construction with specialized valves and seals to minimize heat transfer during fluid transfer operations. The port maintains a closed system during operation to prevent atmospheric contamination and moisture ingress while allowing precise flow control through integrated valves and pressure regulation mechanisms.
Materials
Stainless steel 316L (primary), with cryogenic-grade elastomers (PTFE, Kalrez) for seals, and vacuum-jacketed construction with multilayer insulation (MLI) for thermal protection
Technical Parameters
  • Flow Rate 10-100 L/min (liquid)
  • Heat Leak <1.5 W/m
  • Port Size 1/2" to 2" NPT or ISO
  • Vacuum Level <10^-3 mbar
  • Connection Type Bayonet, Tri-Clamp, or Flanged
  • Maximum Pressure 10-25 bar
  • Operating Temperature -196°C to 50°C
Standards
ISO 21013, DIN 28400, ASME B31.3

Frequently Asked Questions

What maintenance is required for cryogenic fill/dispense ports?

Regular inspection of seals and valves, vacuum integrity checks every 6-12 months, and cleaning with appropriate cryogenic-compatible solvents to prevent ice buildup and contamination.

Can these ports be used with different cryogenic fluids?

Yes, but material compatibility must be verified. Ports designed for liquid nitrogen may require different seals or materials for oxygen service due to oxidation risks.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
