1. Power Press This machine cuts steel sheets into round shapes based on the cylinder size. It ensures precision and efficiency in the initial forming stage.

2. Hydraulic Shell Forming Machine It presses the round sheet into a shell using dies, ensuring accurate shaping for the next production steps.

3. Automatic Trimming Machine This high-efficiency machine uses air-jacket clamping, automatic feeding, and trimming with an inclining hob. The edge width and slope are adjustable, making it reliable and easy to operate when integrated into the production line.

4. Hole Punching Machine Used to punch holes at the top of the cylinder, essential for valve installation.

5. Valve Seat Welding Machine It completes the welding of the valve seat ring joints. The machine ensures uniform appearance, proper weld penetration, and meets all technical requirements. It uses submerged arc welding technology for one-time girth welding.

6. Bottom Base Welding Machine This machine performs automatic girth welding on the bottom base of the cylinder. It ensures concentricity, good appearance, and meets technological standards. It uses COâ‚‚ gas shield welding for one-time welding.

7. Protection Enclosure Welding Machine Similar to the bottom base welding machine, it ensures consistent quality, ease of operation, and one-time welding with COâ‚‚ gas shielding.

8. End Dish Shaping Machine Designed to shape the end dish of the cylinder, ensuring accurate dimensions and smooth edges.

9. Assembling Machine This machine assembles both halves of the cylinder, preparing them for final welding and finishing processes.

10. Circumferential Seam Welding Machine Technical Data:
Description Data
Payload Capacity 200kg
Wall Thickness 2.0-4.0mm
Rotation Speed 0.05-0.5rpm
Diameter Coverage OD300-OD500mm
Speed Regulation AC Frequency Conversion
Suitable Workpiece Length 1500mm
Clamping Pneumatic Cylinder
Support Manual Operation Support


This machine produces high-quality welding seams with a clean and professional look. It only requires an on-off signal during the welding process, allowing the entire seam to be completed without interruption, increasing efficiency and improving weld quality. It is easy to operate and install, reducing the need for skilled labor.

11. Annealing Furnace Designed to anneal LPG cylinders using flame from a gas burner. It includes a burner, combustion chamber, smoke collector, rails, chain roller, and exhaust system. Features include adjustable time, self-controlled thermometer, excellent heat treatment results, and minimal pollution.

12. Sandblast Machine Removes rust, oxide layers, and burrs from pipes. It cleans welding slag, reveals a metallic luster, improves paint adhesion, and enhances surface durability and anti-rust properties. This improves the overall quality and lifespan of the steel tube.

13. Plastic Coating Machine Applies a protective coating to the cylinder surface, preventing rust and corrosion.
