Browning Posted March 26, 2004 Report Share Posted March 26, 2004 Paul, Check out your local dive shops, you may find they're cheaper than gunshops. Also, you can pick up cheap secondhand tanks from the dive websites. (Google search for diving should get you there) I'm pretty sure that they now have to be tested every two/three years, so if buying secondhand make sure it's till in test (Last test date will be stamped on the collar) Quote Link to comment Share on other sites More sharing options...
webber Posted March 26, 2004 Report Share Posted March 26, 2004 Brownings advise is prety sound. Cylinders used or intended for diving service require a periodic test and visual inspection by a competent authority every 2 years. It is an offence under the pressure systems regulations, and other legislation to fill a cylinder that is outside test. You should however be very carefull with the 300 Bar cylinders. You do not state if this is 300 Bar test or fill pressure. Cylinders will be stamped with both the service pressure CP and test pressure TP Donot get confused and fill a cylider to its test pressure by mistake, these cylinders have no pressure relief devices, and catastrophic failure could occur under certain conditions, ie over heated cylinder. Most pre-charged air weapons operate at a fill pressure of around 200 Bar. There is nothing to be gained by over pressureising the weapons reservoir, infact quite the oposite. As the fill kits supplied by the gun shops donot offer any form of controlled pressure regulation it is all too easy to pressureise a weapon to 300 Bar or so from a newly filled host cylinder. Some years ago my friend had an early Daystate, he filled the gun, and placed it against a radiator for a minute or so. BOOM, the reservoir just opened up, good job he didnt have hold of it. Just because its air, dont think that it cant go bang, there is a lot of stored energy there. webber Quote Link to comment Share on other sites More sharing options...
Davrian Posted March 30, 2004 Report Share Posted March 30, 2004 Here's a tip for everyone! If you tell the shop what you are using the cylinder for when you get it tested, they can put a sticker on it saying "Surface use ONLY" & then it only needs testing every 5 years as the laws are different for diving! I'm not sure if they can do this to a new cylinder or if it will need retesting but worth asking if your buying new? Chris. Quote Link to comment Share on other sites More sharing options...
