2. Core Product Specifications
(1) Key Dimensions
• Inner Diameter: 2500mm, designed for large-scale pressure vessels, suitable for large reactors, storage tanks and other equipment commonly used in chemical, food, new energy and other industries. Adopting advanced CNC machining technology, the inner diameter deviation is strictly controlled within ±1.0mm, which can realize seamless connection with the tank body, greatly reduce the assembly gap and improve the overall sealing performance of the equipment.
• Nominal Thickness: 6mm, accurately designed according to the common working pressure range of 0.1MPa - 100MPa and the characteristics of various corrosive and non-corrosive media. While ensuring that the structural rigidity is sufficient to resist pressure impact, it effectively reduces the redundant consumption of materials and achieves a balance between performance and cost.
(2) Material Characteristics
It adopts S30408 stainless steel (equivalent to the high-end model of 304 stainless steel). The raw materials are all from domestic first-class suppliers, and a complete Material Test Certificate (MTC) is provided with the goods. This material contains 18% chromium and 8% nickel, which belongs to food-grade alloy. It can form a stable oxide protective film on the surface, excellent in resisting corrosion in acid and alkali environments, eliminating medium pollution, and suitable for scenarios with high cleanliness requirements.
3. Manufacturing & Processing Advantages
(1) Forming Technology
Cold forming technology is adopted, which is very suitable for the processing of thin to medium-thickness specifications of S30408 material. This process can avoid material deformation caused by hot working and completely retain the original mechanical properties of the material such as ductility and weldability. The company is equipped with 10 sets of 1000-ton hydraulic presses, which can accurately control the 2:1 major-to-minor axis ratio of the elliptical dished head, and strictly comply with the requirements of GB/T 25198 and ASME standards, ensuring uniform stress distribution of the head under pressure and improving the operation safety of the equipment.
(2) Quality Assurance
1. Inspection Protocols: 100% full inspection is implemented for the key performance indicators of products, including ultrasonic testing (UT) to detect internal defects, liquid penetrant testing (PT) to check surface flaws, and 3D laser scanners to verify dimensional accuracy, ensuring that each product meets the quality standards.
2. Applicable Standards: Fully comply with international mainstream standards such as GB/T 25198-2010 (China), ASME BPVC Sec.VIII Div.1 (North America), PED 2014/68/EU (Europe), ensuring that the products can smoothly enter the markets of various regions around the world.
3. Certifications: It has passed ISO 9001:2015 Quality Management System, ISO 14001:2015 Environmental Management System certification, and obtained ASME "U" Stamp approval, demonstrating the excellent strength of the products in the field of quality and safety.
4. Applications & Market Performance
Main Applications
With its excellent performance, the 2500*6 S30408 EHA elliptical dished head is widely used in the following fields:
• Chemical Industry: Used in corrosive liquid storage tanks, high-pressure reactors and other equipment to resist corrosion of chemical media and ensure production safety.
• Food & Beverage Industry: Suitable for large milk processing tanks and juice storage equipment, meeting food-grade hygiene requirements and avoiding raw material pollution.
• Pharmaceutical Industry: Applied in sanitary-grade reactors and sterile storage containers, meeting the high cleanliness standards of pharmaceutical production.
• New Energy Industry: Used in large hydrogen storage tanks and battery material mixing tanks, adapting to the requirements of the new energy industry for high pressure resistance and corrosion resistance of equipment.
5. Packaging & Customization
(1) Packaging
Adopting export-grade packaging standards: single precision heads are packed in fumigated wooden crates to ensure no damage during transportation; bulk orders use steel pallets with a load capacity of ≥1000kg, and all packages have shockproof and waterproof functions to fully protect the integrity of products during transportation.
(2) Customization Services
• Specification Customization: According to customer needs, personalized products with inner diameter ranging from 60mm to 12000mm and thickness ranging from 1mm to 300mm can be provided.
• Technical Support: Free technical services such as Finite Element Analysis (FEA) stress calculation and 2D/3D drawing design are provided to help customers optimize equipment design schemes.
• Sample Delivery: Customization of 3 - 5 samples is supported, and the samples can be produced and delivered within 20 working days for customers to conduct performance tests.
6. Product Core Advantages
(1) Structural Reliability
The scientific combination of 2500mm inner diameter and 6mm thickness, combined with the cold-formed elliptical structure design, enables the head to disperse stress evenly under pressure, effectively reducing the risk of deformation and leakage, and improving the overall service life of the equipment.
(2) Hygiene & Corrosion Resistance
The S30408 material combined with surface polishing treatment of Ra ≤ 0.8μm fully meets the strict hygiene standards of the food and pharmaceutical industries, eliminating cross-contamination from the source, and at the same time has strong corrosion resistance, suitable for various complex working conditions.
(3) Global Compatibility
Complying with multi-national standards and certification requirements, it can be easily integrated into the global supply chain system. Whether customers are facing the domestic or international market, there is no need to worry about product adaptability.
