Gas Cylinder Manufacturing Process #job #works #skills #machine #iron - Video

Hello Everyone !
This video shows the manufacturing process of gas cylinders (such as oxygen cylinders and industrial gas cylinders), a precision mechanical technique requiring extremely high temperatures. Below is a summary of the main steps: High-pressure gas cylinder manufacturing process. This process usually begins with high-quality stainless steel or alloy steel pipes, which then undergo thermal deformation stages to shape them: • Cutting and Heating: The steel pipes are cut into sections to fit the cylinder size. Then, the pipe ends are placed in a high-frequency heating furnace to be heated to a red-hot state (usually above 1000°C), making the metal ductile and easily molded. • Spinning: As you can see in the video, the red-hot pipe section is spun at extremely high speed. Rollers press down hard on the pipe end, gradually reducing the diameter to form a dome or neck of the cylinder. This process creates a seamless metal, eliminating the need for welds and ensuring optimal strength.
• Neck and Bottom Machining: After shaping the body and neck, the machine will trim the excess material and create threads on the neck of the tank for valve installation.
• Heat Treatment and Testing: After shaping, the tank will be hardened and tempered to achieve the desired hardness and strength.
Finally, each tank must undergo hydrostatic pressure testing to ensure there are absolutely no leaks or cracks when containing compressed air.
