Hi, I'm new to blacksmithing, just building the shop for my future house. Thats right the shop is being built first:-)
I have started to research propane tank rules etc. Here is what I have been told and was wondering how much of it is true. Please correct me and add info and references.
Things with ?? are answers I got which caused more question to pop into my head.1) Tanks under 40 lbs requre the "new" valve with the triangle shaped handle. This indicated a valve that can limit the amount of propane that can be put into the tank.
2) Tanks that are designed to contain more than 40lbs do not need this valve.3)Tanks under 40 lbs and over 10 yrs old need to be hydro-tested every 5 years.
4) tanks over 40 lbs only need to be visually inspected. ?? by who?? ?? what are they looking for??5) Tanks that are label as ASME and not DOT tanks do not require inspection, only up-to-date relief valve. These tanks are often refered to as fork-lift tanks.
Questions I have.
Is there a reference that defines the numbers that are stamped on the neck of most high preasure tanks.
I know the difference between Oxygen and acyldlene tanks, even if I cant spell correctly:-)
How about other high preasure gases like nitrogen, argon or hydrogen. Does each tank have a different code?
Can a tank for say CO2 be switched to argon, or a o2 be switched to hydrogen.
Is it always the rule that non-flamable gases use right hand threads and flamable gases use left handed threads.
Are regulatory specific to the gas. Is there more than just high preasure and low preasure?
I'm sure I will think of more later. Al
