Refrigerant cylinders are normally tested by the manufacturer/supplier.

As you are a welding inspector I am hoping that you are not proposing to manufactur cylinders without the proper knowledge. That would be extremely deadly to any of your customers.

Old ones= steel
recent ones=aluminium
new ones=teflon/carbon mixture

is this for recup or distribute?
