S30408 2:1 Stainless Steel Elliptical Dished Head With Reduced Opening

This precision-engineered component is designed for small and medium-sized high-pressure equipment in demanding industrial applications.

• Model: 2:1 Elliptical Dished Head with Reduced Opening (EHA450×4), S30408 stainless steel construction
• Dimensions: 450mm inner diameter with customizable reduced opening (50-180mm)
• Precision: ≤ ±0.6mm concentricity tolerance, ≤ ±1mm diameter tolerance
• Thickness: 4mm nominal thickness with ≤ 0.3mm deviation
• Pressure Rating: 0.5MPa-10MPa operational range

S30408 food-grade stainless steel offers excellent corrosion resistance against atmospheric conditions, weak acids, alkalis, and organic media. Complies with food/pharmaceutical hygiene standards with complete MTC documentation from certified suppliers (Taiyuan Iron and Steel, Baosteel).

• Enhanced Pressure Capacity: 30% greater pressure-bearing capability than standard elliptical heads
• Hygienic Construction: Easy-clean surface with food contact certification
• Integrated Design: Reduced opening eliminates secondary welding, decreasing leakage risk by 30%

Cold forming via 800-ton hydraulic press with specialized 2:1 elliptical mold maintains material integrity. Produces defect-free surfaces with optimal structural strength.

• Standard chemical polishing (Ra ≤ 1.6μm)
• Passivation treatment for enhanced corrosion resistance
• Optional mirror polishing (Ra ≤ 0.8μm) or sandblasting (Ra 1.6-3.2μm)

• 100% Ultrasonic Testing (UT)
• Penetrant Testing (PT) for surface defects
• Precision dimensional verification
• 1.5× rated pressure hydrostatic testing
• Comprehensive visual inspection
