- What change is taking place?
BOC is upgrading Grade A and CP Grade helium L-size 200 bar cylinder packages to a 300 bar offering.
- Why are we introducing this new package?
Our customers are constantly asking for more gas within their cylinder package. With this new 300 bar helium cylinder package, BOC will provide you with 43% more gas than your existing L-size cylinder. As a result, this means fewer cylinder changeovers, reduced order placing and reduced cylinder holdings.
- Are the cylinder dimensions the same?
The cylinder is 1540mm high and 230mm diameter. However, the guard is 50mm taller on the new 300 bar package.
- Will the cylinder look different?
Yes, as well as being taller due to the height of the new guard, the package has a contents gauge, and the labelling will identify it as being 300 bar filled.
- What is the gas volume of new 300 bar cylinder?
The contents have increased from 9.05m
3 to 12.98m
- Does the cylinder have a different valve?
Yes. The new valve is a pressure reducing valve which will take the outlet pressure down from 300 bar to between 120 - 150 bar. During usage, the outlet pressure will continue to reduce commensurately and be in the region of 40-50% of the contents pressure reading.
- Do I need a new regulator?
No. The outlet connection remains BS3 and due to the pressure reducing valve capability, your existing 200 bar compatible regulator will continue to be suitable.
- What will the contents gauge show?
The contents gauge is an indication of cylinder pressure at 15 degrees centigrade. Therefore the gauge will indicate the actual pressure of the cylinder which, when full, will be 300 bar. Note that the valve outlet pressure will always be below 200 bar and typically 40-50% of the actual cylinder pressure.
- What is the purpose of the red cap?
This has two purposes. Firstly, it protects the safety device (relief valve) from ingress of contamination; and secondly it acts an indicator to confirm if the relief valve has previously activated, i.e. the cap will be dislodged. If the cap is dislodged, the cylinder MUST be returned to BOC as a faulty cylinder.
- Does my downstream system connected to the helium supply need to be 300 bar rated?
No. This is because the cylinder valve has already reduced the outlet pressure to below 200 bar. If the pressure reducing valve fails, a pressure safety devise incorporated within the cylinder valve will activate and relieve any pressure above 200 bar to atmosphere.
- What about smaller sized cylinders?
At this time, there are no plans to upgrade to 300 bar across our small helium cylinder population.
- Has the price of my cylinder package changed?
Please refer to your individual 300 bar helium launch letter for price information. Alternatively, please contact our Customer Service Centre on 0800 111 333.
- Is there a new material number for this product?
Yes. It is 169800-XL for Grade A Helium, replacing 101720-L and CP Grade Helium is 171698-XL, replacing 271088-L. Certified options remain in place for the new package as well.
- When will I get my new cylinder?
BOC is managing a phased roll-out of the new 300 bar helium package across the UK, commencing May 2015. At the time of placing your helium order with BOC, you will be informed when the new package becomes available.
- What do I need to do?
BOC will advise you when they are ready to supply your first 300 bar cylinder, at the time of placing your helium order. The new material code and pricing will need to be set up in your procurement/account systems.
- Who do I contact if I have further questions?
In the first instance, please contact your BOC Account Manager or our Customer Service Centre on 0800 111 333(UK) or 1890 355 255(Ireland).
