Unlike welded tubes, seamless tubes eliminate longitudinal welds, providing superior pressure resistance, improved fatigue performance, and greater structural reliability under repeated filling cycles.
Dimensional inspections are carried out throughout the forming process to verify concentricity, straightness, wall thickness uniformity, and surface quality.
3. Hot Forming and Neck Spinning
After seamless tubes are prepared, both cylinder ends are formed using precision hot spinning equipment. The steel is heated to the required forming temperature before rotating at controlled speeds while specialized spinning rollers gradually shape the cylinder neck and bottom.
Hot spinning creates a seamless transition between the cylindrical body and dome ends while maintaining uniform wall thickness. This process significantly improves pressure resistance and reduces stress concentrations that could affect long-term fatigue performance.
Modern CNC spinning machines provide excellent dimensional consistency and repeatability for high-volume production.
4. Heat Treatment
Heat treatment is one of the most critical manufacturing stages because it determines the final mechanical properties of the cylinder. After hot forming, cylinders undergo controlled quenching and tempering to optimize strength, toughness, ductility, and fatigue resistance.
Temperature, heating time, cooling rate, and furnace atmosphere are precisely controlled throughout the process to ensure uniform mechanical properties across the entire cylinder body.
Proper heat treatment significantly improves resistance to cyclic pressure loading and extends the service life of the cylinder.
