What are the manufacturing steps of an elliptical head?

The manufacturing steps of an elliptical head typically include the following:

1. Material Preparation & Inspection

Select steel plates (e.g., carbon steel, stainless steel) that meet pressure vessel standards. Conduct inspections (chemical composition analysis, mechanical property testing, surface defect check) to ensure material qualification.

2. Blanking

Calculate thedeveloped size of the elliptical head based on design parameters (diameter, thickness). Cut the steel plate into a circular or oval blank using CNC cutting (plasma, flame, or laser cutting) for accuracy.

3. Forming

Use stamping (most common for standard heads): Place the blank on a die, then press it with a punch to shape it into a half-ellipsoid with a straight cylindrical section. For large or thick heads, spin forming (rotating the blank while pressing with a roller) may be used to achieve the elliptical curve.

4. Trimming & Edge Processing

Trim the uneven edge of the formed head to meet the required diameter. Machine the edge into a坡口 (V-type, U-type) to facilitate welding with the vessel shell.

5. Heat Treatment (if needed)

For heads made of high-strength steel or those with severe forming deformation, perform heat treatment (e.g., annealing) to eliminate internal stress and restore material toughness.

6. Inspection

Conduct dimensional inspections (ellipticity, straight section length, thickness), surface inspections (visual, penetrant, or ultrasonic testing for cracks), and pressure tests (if required) to ensure compliance with design and safety standards.

7. Surface Treatment & Finishing

Clean the surface (remove rust, oil, or scale). For corrosion-resistant needs, apply treatments like pickling, passivation (for stainless steel), or painting.
