Our experts will help you select the most suitable cylinder for your application before purchase.
Cylinder prices vary depending on the gas type, cylinder capacity, order quantity, and delivery conditions. Contact our sales team for a customized quotation based on your specific requirements.
The better choice depends on your type of application. Steel models are more durable, while aluminum models are lighter.
Accordingly, for heavy industrial environments with low mobility, a steel cylinder is more economical and durable. However, for medical and portable/mobile applications, the aluminum version is considered a better option due to its lower weight.
Hydrostatic Test
A periodic pressure test performed to verify the structural integrity and safety of a gas cylinder under high-pressure conditions. This inspection is typically required every five years, depending on applicable regulations and cylinder specifications. Cylinders with an expired hydrostatic test must not be refilled, as using or purchasing them poses a significant safety risk.
Yes, cylinders can be supplied empty, full, or as an exchange, depending on the customer’s needs
No. Cylinders whose test date has expired, that show corrosion or physical damage, or whose construction standard has not been certified, cannot be refilled. Refilling a non-standard cylinder is both illegal and a serious safety hazard. Bonyan Gas performs a technical inspection before every refill.
Medical cylinders are subject to stricter gas purity requirements and inspection, and must be certified by the Food and Drug Administration [organization]. For more complete information, please see the page for each gas
Yes. In this case, maintenance and periodic testing are the responsibility of Bonyan Gas. Details can be discussed via phone/contact
The periodic test date, along with the test pressure value (in bar), is stamped in month/year format on the neck of the cylinder. In accordance with the safety requirements for pressurized cylinders, if more than 5 years have passed since the last recorded date, the cylinder is considered expired, and refilling it will require a hydrostatic test and a new technical certification.
The price of gas cylinders is influenced by various factors such as cylinder capacity, body material, working pressure, manufacturing standard, new or used condition, hydrostatic test validity date, valve and fitting type, transportation costs, and market and raw material conditions. For this reason, to receive an accurate price, you need to specify your required specifications so that the most suitable option can be recommended.
