FREQUENTLY ASKED QUESTIONS
What is a 250 cu ft high pressure cylinder used for?
It is a shop and production scale cylinder used across industrial gas service where a smaller bottle would need constant refilling. The gas it holds is determined by the valve fitted and by what your filler puts in it, not by the cylinder itself. At this size it is a fixed installation rather than a portable bottle.
What is the difference between service pressure and test pressure?
Service pressure is the pressure the cylinder is rated to be filled to in normal use. Test pressure is the higher pressure applied during hydrostatic requalification to prove the cylinder is still sound. Both figures are stamped on the cylinder and both are listed on this page. A filler will fill to service pressure, never to test pressure.
How is this cylinder moved and stored safely?
Store and use it upright, secured by chain or strap so it cannot fall, with the cap fitted whenever a regulator is not attached. A cylinder of this height and weight is not walked on its base; use a cylinder cart or a proper handling frame. Keep it clear of direct heat and ignition sources.
What does "standard valve" mean on this listing?
It indicates the cylinder is supplied with the common valve configuration for its service rather than a specialized or custom fitting. The specific CGA connection determines which gases and regulators it suits, so confirm the connection at quote stage if your application requires a particular one. We stock a wide valve range alongside the cylinders.
Does the cylinder ship filled?
No. All cylinders ship empty for transport safety and are filled by a qualified gas supplier. Specify the gas and any purity requirement at the time of fill.
Can we order 250 cu ft cylinders in volume?
Yes. All Safe Global supplies gas distributors, fillers and industrial accounts at wholesale, and pricing improves with quantity. Request a quote with your quantity, valve requirement and delivery point, and we will confirm availability and freight.
What does DOT and TC approval mean?
It means the cylinder is manufactured and marked to United States Department of Transportation and Transport Canada specifications, which is what makes it legal to fill and transport in those markets. The specification, serial number and test date are stamped into the collar, and a filler reads them before every fill.
When does a high pressure steel cylinder need requalification?
On a set DOT interval measured from the last test date stamped into the collar. Suppliers check that stamp at every fill and refuse an out of date cylinder. A new cylinder enters service with a current date and a full interval ahead.
Can All Safe Global requalify cylinders we already have in service?
Yes. We operate DOT-authorized requalification centers providing hydrostatic and ultrasonic testing and visual inspection, alongside blasting, repainting and customization. Fleet work is quoted per cylinder against volume, and this is often the lower cost route compared with replacing sound cylinders.
Do you supply cylinders in a custom finish or with customer branding?
Yes. Blasting, repainting and custom finishing including customer branding are part of our service offer, and they are commonly specified on volume orders. Raise it at quote stage, since finishing affects both lead time and cost
