Elliptical Dished Head EHA900*5-304 – Premium Craftsmanship by Henan Guojiang Precision Formed Head
Product Description:
Brand
As a leading domestic manufacturer specializing in precision pressure vessel components, Henan Guojiang boasts 12+ years of expertise in R&D, production, and customization of dished heads. Our products are trusted by clients across 60+ countries, with a strong focus on meeting high-standard industrial demands for reliability and precision.
Core Product Specifications (EHA900*5 304)
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 minimizing assembly gaps.
Calibrated based on typical operating pressures (0.1MPa – 80MPa) and compatibility with corrosive/non-corrosive media. The thickness design optimizes structural rigidity while reducing unnecessary material consumption, aligning with cost-efficiency goals.
- Material: 304 Stainless Steel
Sourced from top-tier suppliers (e.g., Shanxi Taigang, Jiangsu Shagang) with full Material Test Certificates (MTC) provided. This food-grade alloy features excellent corrosion resistance—its chromium (18%) and nickel (8%) composition forms a stable oxide layer, effectively withstanding acidic/alkaline environments and preventing media contamination, making it suitable for hygiene-critical applications.
Manufacturing & Processing Advantages
- Forming Technology: Cold Forming
Ideal for SUS304 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.
Quality Assurance
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.
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.
ISO 9001:2015 (Quality Management System), ISO 14001:2015 (Environmental Management System), and ASME "U" Stamp approval, reflecting our commitment to quality and regulatory compliance.
Applications & Market Performance
The EHA900*5 SUS304 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 & Customization
Export-grade wooden crates (fumigated) for single-piece precision heads; steel pallets (load capacity ≥ 800kg) for bulk orders. All packaging is shockproof and waterproof, tested to withstand long-distance transportation.
- Tailored specifications (diameter: 60mm – 10000mm; thickness: 1mm –300mm) based on client drawings.
- Free technical support: FEA stress analysis, 2D/3D drawing design, and on-site installation guidance.
- Sample delivery: 3–5 pieces available for performance testing within 20 working days.
After-Sales Support
- 24-hour technical consultation hotline; on-site troubleshooting within 72 hours for domestic clients, and 5 working days for overseas clients.
-
As a "critical safety component" for mid-sized pressure vessels, the EHA900*5 304 elliptical dished head stands out for its:
- Structural Reliability: The 900mm diameter and 5mm thickness combination, paired with cold-formed elliptical design, ensures uniform stress distribution under pressure, reducing the risk of deformation or leakage.
- Hygiene & Corrosion Resistance: SUS304 material and Ra ≤ 0.8μm polishing meet the strictest hygiene standards, eliminating cross-contamination risks and making it ideal for food/pharmaceutical use.
- Cost-Efficiency: Optimized thickness and material selection balance performance and cost, while the durable design lowers long-term maintenance expenses.
- Global Compatibility: Compliance with multiple international standards and certifications enables seamless integration into global supply chains, catering to diverse market needs.
From material sourcing to final inspection, Henan Guojiang’s EHA900*5 304 elliptical dished head delivers consistent quality and performance—your trusted partner for enhancing pressure vessel safety and operational efficiency!
