Hello guys I have a question I could not get the answer The lifetime of the propane cylinder? Thanks to those who help me to get an answer Abo Maha
Hi Abo, I think you don't need to worry as all refillable canisters are tested and re-sprayed at the factory before refilling. Regards, Wim
In the US, refillable propane tanks, 20# to 100#, are all date stamped and cannot be refilled after the date on the tank. I seem to recall they have a 10 year lifespan.
Hello Wim In my country is filled with the cylinder At home Not subject to any tested The following image to fill the cylinder in my house I'm sure that this period of validity of the cylinder But I could not get the validity of the cylinder, for example 10 or 15 years
Normally and in most developed countries, they stamp manufacture dates on them so you know. Those tanks that are refilled by authorized dealers (not refilling stations) are required to pressure test tanks ever so often before refilling it otherwise, they can and will lose their license. Ron
In Australia, cylinders are required to be tested every 10 years. No set total expiry dates as I have a 4.5kg bottle of 26 years old. Ian
A lot of the older cylinders are far better than the new ones. Here in New Zealand we need to get the bottles inspected and retested every 10 years as well but also when you get them filled the attendant gives them a visual inspection and tests the valve. The main reason he fails them is rust and its nearly always cylinders that are about 5 years old and either left standing on the dirt next to the bbq or left inside lpg heaters where condensation does its worst. The older bottles were nearly always galvanised so do not suffer this fate
Thank you my friends I hope to find a scientific answer and articles from the same manufacturers of the cylinders The reason is because the fans camping in my collecting cylinders made for more than 40 years old without checking them and this is its great danger, and as time bombs and I'm on a process of awareness for them and I liked that was based on scientific information To convince them, I hope your participation to me with useful information based on scientific facts to these risks, thank you abomaha
I think the reality is that they are or at least used to be over engineered for the job. The valves are brass and when worn out will leak but there will be obvious signs of problems before this happens. Testing every now and then by spraying with soapy water is a good test. The tanks are steel and unless they are rusty or damaged will be ok. As long as the above is correct they should last forever. Its only us that have governments that want to protect us from ourselves at there profit that have to test them every 10 years. I got given a bottle recently that was 30 years old and had been unused for 20 as its test was expired. It passed test no problem and will be 40 at next test. The scouts I used to be with had bottles that were older
Responses nice guys this Cylinders hazardous if they have been tolerated without the use of periodic maintenance of the plant this link from your site has been translated in English http://translate.google.com.sa/tran...=3935686&postcount=3&sl=ar&tl=en&hl=&ie=UTF-8 I expect that the cause of the blast walls of the cylinders for weak non-periodic examination and are being used in my country for more than 20 years This is another link from the site of an Australian, warns of neglect maintenance of cylinders http://www.dme.qld.gov.au/zone_files/petroleum_pdf/brochure_lpgcylinder.pdf I hope to provide me any links to research on this cylinders Your friend Abomaha
A good starting point for your research might be to refer to the relavent standards for cylinder construction. In Australia and New Zealand these are: AS/NZS 2469 for 2 piece cylinders and AS/NZS 2470 for 3 piece cylinders. Most LPG cylinders for domestic and camping use are 2 piece construction. In the US 20# cylinders are specified under DOT 4BW A useful link for cylinder design standards is: ERMA NZ Generally as part of the manufacturing process a test cylinder is subjected to pulsation testing and then a overpressure burst test along with a weld X-Ray. The pressure vessel component of an LPG cylinder if well treated should last for pretty much forever. What kills cylinders is rust and mistreatment dents and knocks. What you do tend to find is the valve will wear. You also need to be mindful of the o rings on the ullage screws on those primus bottles you have images of wear out. Hope this helps John
Professor John has provided me with important information thank you very much and I promise you the subject of Creative Commons is coming soon
Important link to the transport system in USA cylinders http://www.osha.gov/SLTC/etools/evacuation/portable_hydro.html Does this mean that the age of five years before the cylinder that is factory maintenance? Abomaha
Hi, Your link is to the hydrostatic testing requirements for Fire extinguishers?? The hydrostatic process for LPG cylinders is the same. Generally the test interval for a Steel shelled lPG cylinder is 10 years not 5. Can I ask why you are asking about this.. Apart from interest sake??
Hi johnsnz Answer to your question in Saudi Arabia used my amateur camping trips before the gas cylinder manufacture more than 10 or 20 or 30 years without any maintenance or testing laboratories and does not have any of this matter, I do have an awareness campaign through the site dedicated to Camping Abomaha
