Standard 2:1 Elliptical Head with Inner Surface Polished (Ra ≤ 0.15μm), Inner Diameter 800mm For Biopharmaceutical Equipment
Brand Overview
As a benchmark manufacturer in China's precision pressure vessel component industry, Henan Guojiang has specialised in the R&D, production, and customisation of standard 2:1 elliptical heads for over 12 years. Our products are exported to more than 10 countries worldwide, meeting the high-standard production requirements of the biomedical industry, and providing reliable core component solutions for various biomedical pressure-bearing equipment.
Specifications
Head Type: Standard Elliptical Head (2:1 Ratio)
Inner Diameter: 800mm - Suitable for medium and large-scale biomedical equipment such as bioreactors, medical consumable storage tanks, and sterile batching tanks
Nominal Thickness: 6mm - Optimised design for working pressure range of 0.1MPa-50MPa, compatible with biomedical-specific media such as biological agents and buffers
Material: 316L Stainless Steel - Each batch is equipped with a complete Material Test Certificate (MTC)
Material Composition: 16%-18% chromium, 10%-14% nickel, and 2%-3% molybdenum, offering excellent corrosion resistance and anti-biological contamination performance
Manufacturing & Processing Advantages
Produced via cold forming technology to fully retain the original ductility and weldability of 316L stainless steel. Advanced hydraulic forming equipment ensures compliance with GB/T 25198 and ASME standards. The inner surface is polished (roughness Ra ≤ 0.15μm) with a smooth, seamless, and uniform finish, avoiding local stress concentration and meeting the sterility requirements of biomedical equipment.
Quality Assurance
Inspection Process: 100% full inspection, including ultrasonic testing (UT), penetrant testing (PT), and 3D laser scanning, eliminating micro-defects
Compliance Standards: GB/T 25198-2023, ASME BPVC Section VIII Division 1, PED 2014/68/EU directives, and GMP (Good Manufacturing Practice) for pharmaceutical production
Certifications: ISO 9001:2015, ISO 14001:2015, ISO 13485 Medical Device Quality Management System Certification, and ASME "U" Stamp approval
Applications
Specifically designed for the high sterility and corrosion resistance requirements of the biomedical industry, applicable to:
Head components of bioreactors and cell culture tanks
Sterile storage tanks for medical consumables and turnover tanks for biological agents
Core components of sterile batching tanks and purified water/injection water storage equipment
Packaging Solutions
Export-grade fumigated wooden cases + sterile protective film wrapping for single-unit precision packaging, avoiding transportation contamination
Sterile-grade steel pallets with a load capacity of ≥ 500kg for bulk orders, meeting clean storage requirements
