Welded Ellipsoidal Head S30408 Open Inner Diameter 2500mm Thickness 6mm

Henan Guojiang Precision Formed Head Co., Ltd. is a leading enterprise in precision components for pressure vessels with over 12 years of experience in R&D, production, and customization of dished heads. The company serves customers in more than 10 countries, maintaining strict control over product reliability and precision to meet high-standard industrial requirements.

• Inner Diameter: 2500mm, designed for large-scale pressure vessels with CNC machining technology ensuring ±1.0mm deviation for seamless tank body connection and improved sealing performance.
• Nominal Thickness: 6mm, optimized for working pressures of 0.1MPa - 100MPa while balancing structural rigidity and material efficiency.

Constructed from S30408 stainless steel (equivalent to high-grade 304 stainless steel) with complete Material Test Certificate (MTC). This food-grade alloy contains 18% chromium and 8% nickel, forming a protective oxide film for excellent corrosion resistance in acid/alkali environments and high cleanliness applications.

Cold forming technology preserves material properties (ductility, weldability) while avoiding heat-induced deformation. Manufactured using 1000-ton hydraulic presses to maintain precise 2:1 major-to-minor axis ratio, complying with GB/T 25198 and ASME standards for uniform stress distribution.

• Inspection Protocols: 100% inspection including ultrasonic testing (UT), liquid penetrant testing (PT), and 3D laser scanning for dimensional accuracy.
• Applicable Standards: GB/T 25198-2010 (China), ASME BPVC Sec.VIII Div.1 (North America), PED 2014/68/EU (Europe).
• Certifications: ISO 9001:2015, ISO 14001:2015, and ASME "U" Stamp approval.

• Chemical Industry: Corrosive liquid storage tanks and high-pressure reactors.
• Food & Beverage: Milk processing tanks and juice storage equipment.
• Pharmaceutical: Sanitary-grade reactors and sterile storage containers.
• New Energy: Hydrogen storage tanks and battery material mixing tanks.

Export-grade packaging includes fumigated wooden crates for single units and steel pallets (≥1000kg capacity) for bulk orders, all with shockproof and waterproof protection.

• Inner diameter customization from 60mm to 12000mm and thickness from 1mm to 300mm.
• Technical support including Finite Element Analysis (FEA) and 2D/3D drawing design.
• Sample production (3-5 units) within 20 working days for performance testing.
