Ordering, delivery and refilling of argon cylinders
Customers can source argon cylinders in three ways: buying a ready full cylinder, refilling their own tanks, or buying a new empty steel cylinder. To speed up the process, simply tell our sales team the volume and purity you need.
All argon cylinders supplied by Bonyan Gas undergo pressure tests and valve checks before shipping. Our support department is also available by phone to arrange and accept orders for renewing and refilling your existing cylinders at your factory or workshop.
Note that this gas is supplied in various purity grades from industrial to laboratory; see the full details of the grades and their uses on the argon gas page.
Cylinder storage safety tips
Following protective protocols when storing argon cylinders safeguards your workplace. These tanks must always be secured upright, and valves must be leak-checked with standard equipment or soapy water before connecting a pressure gauge. Also, to prevent breakage or damage to the valve core during transport, always shut off the gas flow at the end of each shift and screw the protective cap tightly onto the cylinder.
The main difference is the purity of the argon inside the cylinder, not the cylinder itself; see the argon gas product page for details of the purity grades.
Yes, steel argon cylinders can be refilled many times, provided they pass the standard periodic test.
