LPG Cylinder Info

Greetings all,

As my barby cylinders are due for test I have been researching re -testing verses new cylinders. Over the last few years cyl have been getting thinner and thinner. The older cyl are about 4mm thick some of the new about 2mm. As part of the retesting any sort of dent is cause for rejection. So the newer cyl are failing at a greater rate because they are easily dented. Quite a few older cyl are on their 3rd test (thirty years) so if you have older cyl keep them. We are also looking for impact resistance having them mounted right where the stones fly up.

Cost for re-test with a normal valve about $27.50
Cost for re-test with a valve with gauge about $34.50

New 9kgs with a gauge is about $80 and they are thin and might not pass muster at test time.

Just a word about the new poly/fibreglass cylinders .... The 10kg is about $250 to buy and needs retesting every three years not ten. These cyl might be susceptible to impact damage and are not recommended for A-frame mount for obvious reasons unless a stone guard is protecting them.
Currently no testing facility is able to do these or prob more correctly wants to because the test for fractures might involve sonic or dye testing. Because they are so new testing them is a bit of an unknown quantity. This would change within three years you would think. Maybe the cyl would also be rejected if it was scratched on the poly surface.

Our old cylinders are quite tough, they sit in a steel frame rubbing all day long, have stones pelted at them on dirt roads and come back for more.
