Cold rolled steel is deep drawn in progressive stages. Heat treating and several cleaning steps are needed before the cylinders are cleaned. It takes massive presses and a lot of automation to fabricate these disposable cylinders in large quantities. Consistency is everything.
Gas filled cylinders need to be handled with caution. They are pressure vessels with a limit as to how much pressure they can hold. While each cylinder design has its' own inherent limitations, most disposable cylinders are designed to have a burst strength limit of around 6,400 psi, some go to 12,000 psi. But this is relative to the filling pressure and the type of gas being filled. In North and South America we are pleased to offer the patented safe sealing cap. This is the puncturable cap on top of the gas filled cylinder. It is designed to allow a slow and controlled release of gas pressure. There is a video below which demonstrates this. Do not heat a filled cylinder.
