Understanding the Specifications of Hydrogen Storage Tanks for Industrial Needs
A deep dive into the critical parameters for hydrogen storage, including pressure ratings and material selection for safety in industrial environments.
Precision-engineered high-pressure containment solutions for Hydrogen, Nitrogen, Helium, and Argon. Designed for industrial gas distributors seeking certified quality and OEM customization without intermediary costs.
Seamless Steel Gas Cylinders are high-strength pressure vessels manufactured from chromium-molybdenum steel (such as 34CrMo4) without welding seams, ensuring superior structural integrity for high-pressure gas storage. The 108mm to 232mm diameter cylinder range is the industry standard for transporting permanent gases like Oxygen, Nitrogen, Hydrogen, and Argon, as well as liquefied gases like Carbon Dioxide.
These cylinders are critical for industrial applications, medical oxygen supply, and specialty gas mixtures. Junxin Energy manufactures these units in strict compliance with ISO9809, EN1964, and DOT standards to ensure safety during transport and storage under pressures ranging from 150 bar to 300 bar.
| Outer Diameter | 108mm - 232mm (Customizable) |
| Water Capacity | 5L to 50L (Standard Range) |
| Working Pressure | 150 Bar / 200 Bar / 300 Bar |
| Material | 37Mn / 34CrMo4 Steel |
| Manufacturing Standard | ISO9809, EN1964, DOT-3AA |
| Gas Compatibility | H2, O2, N2, He, Ar, CO2, Air |
Every cylinder undergoes rigorous hydrostatic expansion testing and ultrasonic flaw detection to ensure zero leakage risks.
We provide fully assembled units with QF-2, QF-2C, or CGA series valves and protective caps tailored to your regional market.
Optimized production lines allow us to fulfill large-volume container orders with consistent delivery schedules.

Our typical MOQ is one 20ft container, which helps optimize shipping costs for heavy seamless steel products. However, for standard specifications (like 40L or 50L oxygen cylinders), we can discuss smaller trial batches.
Yes, we offer complete assembly services. We can install QF, CGA, or other standard valves and provide safety caps (tulip or standard metal) based on your requirements.
Our seamless steel cylinders are manufactured to meet ISO9809-1, ISO9809-3, and EN1964 standards. We also provide TPED certification for the European market.
Yes, strictly adhering to ISO 32 or local standards. We paint cylinders according to gas type: Green for Oxygen, Grey for CO2, Black for Nitrogen, Red for Hydrogen, etc.
Standard production lead time is 25-35 days after deposit confirmation. For custom molds or non-standard diameters, please allow an additional 10 days.
