Seamless Aluminum & Steel High-Pressure Gas Containers for Clinical and Surgical Applications
Medical Carbon Dioxide Cylinders are seamless high-pressure vessels engineered for the safe storage and delivery of medical-grade CO2. Manufactured from high-purity aluminum alloys (6061-T6) and chrome-molybdenum steel, these cylinders comply with international pressure equipment directives and medical device regulations. Each unit is constructed to maintain internal gas purity and withstand rigorous hospital handling environments.

Clinical Application Parameters
Medical CO2 cylinders are deployed across specialized medical environments where precise pressure control and contaminant-free delivery are mandatory.
Laparoscopic Insufflation: Provides continuous, regulated CO2 flow to expand the abdominal cavity, establishing optimal surgical visualization and working space.
Endoscopic Procedures: Utilized for luminal distension and diagnostic purging during specialized gastrointestinal interventions.
Cryosurgery Units: Supplies liquefied or high-pressure gas for localized tissue freezing in dermatology and gynecology.
Physiological Testing Chambers: Delivers specific gas mixtures for respiratory diagnostics and metabolic testing equipment.
Manufacturing Process & Quality Control
Our production line operates under strict quality management systems (ISO 13485) to eliminate structural defects and ensure metallurgical consistency.
Extrusion & Deep Drawing
Aluminum billets (Alloy 6061) undergo hot reverse extrusion to form a seamless shell, while steel billets utilize multi-stage deep drawing to eliminate structural weld seams.
Heat Treatment
Cylinders undergo controlled thermal quenching and tempering to achieve uniform grain structure, maximizing tensile strength and elongation performance.
Internal & External Surface Treatment
Internal Cleaning: Specialized washing and vacuum drying processes remove residual lubricants, moisture, and particulate matter to meet medical gas purity standards.
Exterior Finish: Shot-blasting followed by electrostatic powder coating provides corrosion resistance and durable color identification.
Mandatory Testing Protocols
Every production batch undergoes destructive and non-destructive testing in accordance with ISO 7866, DOT-3AL, and EN 1964 standards:
• Hydrostatic Pressure Test: Verifies volumetric expansion and permanent expansion limits under test pressure.
• Burst Test: Validates ultimate tensile strength and ensures ductile failure modes.
• Cyclic Pressure Fatigue Test: Measures lifespan by subjecting sample cylinders to tens of thousands of pressure cycles.
• Thread & Dimensional Inspection: Laser-calibrated verification of neck threads (ISO 228, UNF, or metric).
Regulatory Compliance & Certifications
Procurement for healthcare facilities requires verifiable compliance documentation. Our cylinders meet international regulatory frameworks:
Quality Management: ISO 13485:2016 Certified Medical Device Quality System.
European Union: CE Marked under Medical Device Regulation (MDR 2017/745) and Pressure Equipment Directive (PED 2014/68/EU).
North America: DOT-3AL (United States Department of Transportation) and TC-3ALM (Transport Canada) approved manufacturing facilities.
Global Standards: ISO 7866 (Seamless aluminum alloy gas cylinders) and EN 1964-1 (Seamless steel gas cylinders).
Procurement & Supply Chain FAQ
Q: What are the standard lead times for bulk orders?
A: Standard production lead times range from 30 to 45 days upon confirmation of technical drawings, valve specifications, and regulatory label approvals. Expedited schedules can be coordinated for recurring distributor contracts.
Q: Are cylinders shipped filled or empty?
A: To comply with international hazardous materials (Hazmat) transportation regulations, cylinders are shipped empty with protective valve caps. Pre-filled arrangements must be negotiated separately based on local import logistics and dangerous goods transport classifications.
Q: What valve options are available for hospital integration?
A: We supply cylinders equipped with medical pin-index valves (CGA 940), integrated pressure regulator valves (ICV) with built-in flow meters, and standard DIN or CGA threaded outlet valves matched to local hospital pipeline standards.
Q: How is traceability handled for each cylinder?
A: Every cylinder is permanently laser-engraved on the shoulder with serial numbers, batch numbers, manufacturing dates, tare weight, water capacity, test pressure, and certification marks (e.g., DOT/TC/CE), ensuring full lifecycle traceability.
