NETC Aluminum Alloy Gas Cylinders: Delivering Ultimate Purity for High-Purity Electronic Grade Nitrogen Storage and Transportation
In high-tech electronics industries such as semiconductor manufacturing, display panel production, and photovoltaic cells, high-purity nitrogen is far more than an ordinary gas; it is the "lifeline gas" essential for maintaining the production environment and ensuring process yield. It is used not only for purging pipelines and chambers but also plays a critical role in core manufacturing stages. Before Chemical Vapor Deposition (CVD), high-purity nitrogen is key to cleaning reaction chambers and preventing cross-contamination. After ion implantation, it serves as a protective atmosphere for annealing, preventing wafer oxidation at high temperatures. During lithography, it protects precision lens assemblies from oxygen and moisture. The success of these applications hinges entirely on maintaining consistent nitrogen purity at the point of use.
NETC's aluminum alloy gas cylinders, specifically designed for high-purity gases and electronic grade gases, are engineered to meet these extreme demands. Their superior physical properties and advanced internal surface treatment technologies collectively form a robust defense, ensuring "zero contamination" during the storage and transportation of ultra-high purity nitrogen.
Ultimate Internal Cleanliness: Safeguarding Gas Purity from the Source
Electronic grade purge and protective nitrogen require stringent control over particulates and moisture. NETC's aluminum alloy cylinders utilize a proprietary internal surface treatment process, delivering:
Exceptionally Low Particulate Levels: Ensuring internal cleanliness. The specially polished and passivated inner surface features extremely low roughness, fundamentally reducing the release and adhesion of internal particles. This guarantees that the delivered nitrogen meets strict particulate control standards.
Extremely Low Moisture Residue: The smooth, dense inner surface does not adsorb moisture. Combined with a rigorous pre-delivery drying and purification process, this ensures the cylinders have a very low moisture dew point upon delivery, providing an inherent advantage for maintaining the dry characteristics of high-purity nitrogen.
Superior Material Stability: Ensuring "Zero" Interactive Contamination
Unlike standard containers, NETC's aluminum alloy cylinders are designed with material compatibility for high-purity gases in mind:
No Intergranular Corrosion: The aluminum alloy material fundamentally eliminates the risk of intergranular corrosion possible in steel cylinders, preventing metallic ion contamination from corrosion byproducts. This is crucial for protecting wafers during manufacturing.
Reliable Pressure Resistance and Safety: High-purity nitrogen is typically stored at high pressures (150 Bar to 200 Bar) for efficiency. NETC aluminum alloy cylinders are strictly designed and manufactured in accordance with international standards like DOT 3AL and CE ISO 7866. They possess excellent fatigue strength, safely enduring repeated refilling and long-term high-pressure operation.
