Hydrogen Purge Gas is a high-purity gas used to remove contaminants from systems and pipelines. Specialty Gases are ultra-pure gases tailored for specific industrial, medical, or scientific applications. Both are critical for ensuring precision and safety in sensitive processes.

Hydrogen Purge Gas:

Size: Typically supplied in cylinders (50L, 44L), tube trailers, or bulk storage.

Grade: Ultra-high purity (99.999% or higher), industrial grade (99.95%).

Viscosity: Low viscosity (~8.9 μPa·s at 20°C).

Buoyancy: Highly buoyant (lighter than air, density ~0.08988 kg/m³ at STP).

Material: Stored in high-strength steel, aluminum, or composite cylinders.

Specialty Gases (General):

Size: Varies (1L to 50L cylinders, custom bulk options).

Grade: High-purity (99.99% to 99.9999%), calibration, or mixed grades.

Viscosity: Depends on gas type (e.g., argon ~22.7 μPa·s, helium ~19.9 μPa·s at 20°C).

Buoyancy: Varies by gas (helium buoyant, sulfur hexafluoride dense).

Material: Stainless steel, aluminum, or specialty-coated containers.
