Introduction:
Asbestos-free acetylene cylinder is an international advanced product independently-researched by SEFIC. Deep-drawn by one steel plate with advanced technology.
Asbestos-free acetylene cylinder is featured with non-pollution, safety storage of acetylene gas, lightweight, work-of-art appearance. Asbestos-free acetylene cylinder has obtained DOT-8AL certificate and TC-8WAM certificate, and passed technical audition of BOC, the United Kindom. Our asbestos-free acetylene cylinder has been exporting to North American area, European countries and so on.
Note: Acetylene cylinders contain an inert packing material and are filled with a solvent such as acetone or dimethylformamide. The acetylene is pumped into the cylinder and it dissolves in the solvent. When the cylinder is opened the acetylene comes back out of solution, much like a carbonated beverage bubbles when opened. This is a workaround to acetylene's property to explode when pressurized above 200 kPa or liquified.
