304 Stainless Steel Ellipsoidal Head 900mm ID 6mm Thickness Pressure Vessel Dished Head
As a leading domestic manufacturer specialising in precision pressure vessel components, Henan Guojiang boasts 12+ years of expertise in R&D, production, and customisation of dished heads. Our products are trusted by clients across 10+ countries, with a strong focus on meeting high-standard industrial demands for reliability and precision.
- Inner Diameter: 900mm - Tailored to fit mid-sized pressure vessels (e.g., reactors, storage tanks) commonly used in chemical, pharmaceutical, and food processing sectors. Our CNC machining technology ensures diameter deviation ≤ ±0.8mm, enabling seamless integration with tank bodies and minimising assembly gaps.
- Nominal Thickness: 6mm - Calibrated based on typical operating pressures (0.1MPa - 80MPa) and compatibility with corrosive/non-corrosive media. The thickness design optimises structural rigidity while reducing unnecessary material consumption.
- Material: 304 Stainless Steel - Sourced from top-tier suppliers with full Material Test Certificates (MTC) provided. This food-grade alloy features excellent corrosion resistance with chromium (18%) and nickel (8%) composition, forming a stable oxide layer that withstands acidic/alkaline environments and prevents media contamination.
Ideal for 304 material (thin to medium thickness), cold forming avoids thermal deformation and preserves the material's original mechanical properties (e.g., ductility, weldability). Our 8 sets of 800-ton hydraulic presses ensure uniform shaping of the elliptical structure, adhering to the 2:1 major-to-minor axis ratio specified in GB/T 25198 and ASME standards for balanced stress distribution under pressure.
- Inspection Protocols: 100% inspection coverage for key performance indicators, including UT (ultrasonic testing) for internal defects, PT (liquid penetrant testing) for surface flaws, and dimensional accuracy checks using 3D laser scanners.
- Applicable Standards: Compliant with GB/T 25198-2010 (China), ASME BPVC Sec.VIII Div 1 (North America), and PED 2014/68/EU (Europe), ensuring global market access.
- Certifications: ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ASME "U" Stamp approval.
The EHA900*6 304 elliptical dished head is widely used in:
- Chemical industry (corrosive fluid storage tanks, reaction vessels)
- Food & beverage (milk processing tanks, juice storage equipment)
- Pharmaceuticals (sanitary-grade reactors, sterile storage containers)
- New energy (hydrogen storage tanks, battery material mixing vessels)
Our elliptical dished heads hold a 25%+ market share in China's mid-sized pressure vessel component segment, with export volumes accounting for 20% of total sales (major markets: Southeast Asia, Europe, North America).
- Packaging: Export-grade wooden crates (fumigated) for single-piece precision heads; steel pallets (load capacity ≥ 800kg) for bulk orders. All packaging is shockproof and waterproof.
- Customisation Services:
- Tailored specifications (diameter: 60mm - 10000mm; thickness: 1mm -300mm)
- Free technical support: FEA stress analysis, 2D/3D drawing design
- Sample delivery: 3-5 pieces available for performance testing within 20 working days
- 24-hour technical consultation hotline
- On-site troubleshooting within 72 hours for domestic clients, and 5 working days for overseas clients
The 900mm diameter and 6mm thickness combination, paired with a cold-formed elliptical design, ensures uniform stress distribution under pressure, reducing the risk of deformation or leakage.
304 material and Ra ≤ 0.8μm polishing meet the strictest hygiene standards, eliminating cross-contamination risks and making it ideal for food/pharmaceutical use.
Optimised thickness and material selection balance performance and cost, while the durable design lowers long-term maintenance expenses.
Compliance with multiple international standards and certifications enables seamless integration into global supply chains.
From material sourcing to final inspection, Henan Guojiang's EHA900*6 304 elliptical dished head delivers consistent quality and performance—your trusted partner for enhancing pressure vessel safety and operational efficiency!
