FAQ: Scuba Tanks, Materials & Technical Standards

Q1: What is the difference between 6061-T6 and standard aluminum for diving cylinders?

6061-T6 is a high strength, heat-treated aluminum alloy featuring enhanced tensile strength (>290 MPa), improved fatigue resistance, and superior corrosion properties, making it the industry standard for modern scuba tanks for sale.

Q2: What are the common international certifications for a diving oxygen cylinder?

The widely recognized certifications are ISO 7866 (aluminum pressure vessels), DOT (US), CE (EU), and EN 144-1/250 (Europe diving apparatus). These signify safety, traceability, and pressure integrity.

Q3: Why is hydrostatic testing important?

Hydrostatic testing verifies the cylinder's strength and leakage under pressure, typically at 1.5–1.6 times the working pressure. It is mandatory every 5 years (per ISO 6406/EN 1968) for all scuba diving tank products.

Q4: How do I select the right capacity scuba tank?

Select based on the intended dive length, depth, and air consumption rate. For recreational use, 8–12L suffices; professional/industrial may require 15–18L. For emergencies or travel, a personal scuba tank of 1–2L is popular.

Q5: What is the typical service life for an aluminum diving cylinder?

With periodic inspection and retesting, most high-quality aluminum scuba air tanks have a design life exceeding 15 years, with some field units remaining in service for over 25 years.

Q6: Can I use different gas types in my diving tank?

Certified cylinders can be used for air, Nitrox, or oxygen up to specified O2 % (usually up to 40% O2 for recreational). Pure O2 requires O2-cleaned, grease-free, and compatible valves (per EN 144-3/FDA reference for medical gases).

Q7: Are the cylinders suitable for industrial applications beyond diving?

Yes. Diving oxygen cylinders are widely used in petrochemical, metallurgy, water treatment, and research industries, thanks to strong anti-corrosion, pressure stability, and modular customization options.
