I have a couple of small Primus LPG Bottles with a top opening that are out of date, and I am having trouble finding a company that will recertify them, here on the Sunshine Coast. Can anyone help me? The bottles are in excellent condition and one was made by Primus Sweden.
I don't like to say this, but perhaps it will be more economic to replace all of them?
I don't know for sure, but recertification possibly is more expensive than buying new.
I'd love to see you get to reuse not dispose. It's steel after all, much more reusable but certainly in need of being legit and getting a new date stamp and valve
Do you have a local Elgas or BOC Gas place up there? Call them and ask them for leads on who recertifies.
Here we have an empty swap for full. Yes it is probably more expensive on a consumption basis. However it solves the need for retesting and certification.
Another option is to get yourself a set of number stamps and just put the current month and year on the tank. I know of a company that did that with chlorine bottles.
I wouldn’t stamp a bottle as it is a pressure vessel holding a “dangerous” content if it split or exploded I would guess the repercussions would be dire. They may look good on the outside but there’s a good chance there is internal corrosion in the tank or problems within the valve. Unfortunately it is far not economical to replace them. If you really want them done a NDT firm may do them.
Try the LPG Shop just south of Caboolture, the only other option I can think of is a mechanic who does LPG vehicles.
Edit. I just tried the LPG Shop, no answer. If you find someone can you let me know as I have a bottle that needs doing as well.
Gameco recertify them. Prices include refill
gas cylinder retesting after 10 years
Cost for 1kg bottle depends on the valve fitted. $$33.75 with Primus valve and $35.65 with other valve make
9kg is $49.50.
Prices scale for in-between sizes
Cheers
Thanks Lappa. At that price and the distance I'd have to travel, looks like I'll be breaking out the electric gas axe and turning it into a little piggy BBQ, for which I'll need another gas bottle.
Try a Swap'n'Go and get new bottles, they then certify the old ones.
My local Swap bottles only go down to 3.5kg or 4kg depending on the supplier.
are you bothered by the fires further north?Quote:

Thankfully, Ian they are north of us, but we live in a bush setting and they put you on edge. I have sprinklers that mount on the gutters that do a 360 degree circuit wetting the roof and garden area. Maybe they will be of some help if some idiots go lighting fires in our area. Apparently it is the ember attack that burn down 90% of homes.Quote:

I did it with bottles out of date but they may have changed their policy since then as I seem to recall it was one of their big marketing advantages.Quote:

I'm not sure that some of the gas won't have dissolved into the metal of the cylinder. Pays to be sure.Quote:

The amount of gas that dissolve back out of the metal can be minimized by repeatedly pouring boiling water into the bottle. What is much harder to remove is any mercaptan that has bled into any seams and under rust flakes. Mercaptan is the “stink” compound added to gas to give it an odor. Small amount condense in tiny cracks and seams. Adding detergent and shaking the gas bottle helps remove the mercaptan. If you want to really get rid of it then 5/6 fill the bottle and boil the water/detergent mix. Provided the valve is removed the residual mercaptan is not dangerous even if there is enough for ignition - it will make a bit of a “woof” but is a long way from causing any sort of explosion.Quote:

If you're going to attack it with a gas axe, from memory it should be done after the valve has been removed and the tank filled with water. Check the exact requirements. I vaguely remember that the water should have detergent in it, but it's a long time ago.Quote:

Certainly an everyday product that we have become very complacent about. Even see idiots smoking near the "swap n go" cages in front of the big green shed, and they don't like being moved on.Quote:

I too like to re-use things rather than throw them out. I also have one of these small gas bottles that I bought with a Primus torch attachment, and it recently ran out of gas so I was left in the same predicament. After investigating all the options I chose to replace it with a new one from JayCar. It was $29.99 IIRC and uses one of those cheap camping stove gas cans that sell for something like four for $6. There are a couple of advantages to the new unit - it has piezo ignition and it also produces a much better looking flame (strictly subjective :)).
I should add that I don't use this device very much which explains why I've never had it refilled. I bought it in my mid '20s and I'm now 69 so when I was looking for a replacement the question of whether the gas bottles will still be around in another 49 years didn't really enter my head :)
Wow. That's a bit too big to be described as an eyebrow enhancing moment that one.Quote:
