Compared with elliptical dished heads, spherical dished heads offer superior pressure-bearing performance but involve higher manufacturing difficulty. As a result, elliptical structures are more commonly used in medium and low-pressure vessels. When the design pressure exceeds 10MPa, the use of spherical dished heads can reduce wall thickness, significantly lowering material costs. In storage-type vessels, their geometric characteristics can increase the effective volume by more than 15%.

Production & Processing Details
Item Key Data
Forming Methods
  • Hot Forming: Applicable to thick-walled materials/high-strength alloys; stress relief annealing required after forming
  • Cold Forming: Suitable for 8mm-thick 316L stainless steel; no thermal deformation, ensuring structural precision
Surface Treatment
  • Sand Blasting: Ra 1.6μm - 3.2μm (enhances coating adhesion)
  • Pickling: Forms a passive film (improves corrosion resistance, meets hygiene standards)
  • Oil Coating: Food-grade anti-rust oil optional
  • Descaling: Mechanical/chemical descaling (ensures a clean surface before welding)
  • Customisation: E.g., mirror polishing for highly clean fields
Inspection Standards
  • Ultrasonic Testing (UT): 100% coverage of key parts to detect internal cracks and inclusions
  • Radiographic Testing (RT): Complies with ASME BPVC Sec.V Level II standards
  • Penetrant Testing (PT): For non-ferrous materials, ensuring no surface leakage
  • Time of Flight Diffraction (TOFD): Accuracy ±0.1mm, precisely detects internal defects
Standards & Certifications
Item Key Data
Applicable Standards
  • International Standards: ASME BPVC Sec.VIII Div.1/2 (North America & global), PED 2014/68/EU (CE certification for European markets)
  • National Standards: GB/T 25198-2023 (China)
  • Regional Standards: Adaptable to JIS B8243, EN 13445
Certifications
  • ISO 9001:2015 Quality Management System Certification
  • ASME "U" Stamp
  • PED Module H Certification
Application Scenarios
Application Industry Applicable Equipment/Scenarios
