550MM Diameter Dished Head for Liquid Oxygen Cylinder (Upper Part of Outer Layer)
550mm diameter dished head (upper part of outer layer) for liquid oxygen cylinder, manufactured by Henan Guojiang—a leader in pressure vessel components with 12+ years of specialised experience. Our products serve clients across more than 10 countries, meeting rigorous industrial standards for cryogenic storage.
Key Product Features
Structural Reliability: 550mm diameter with customizable thickness ensures uniform stress distribution in low-temperature environments, avoiding brittle fracture risks
Cryogenic Adaptability: SUS304 material maintains excellent performance at -183℃, suitable for long-term liquid oxygen storage
Leak-Proof Performance: Smooth surface (Ra ≤ 0.8μm) and precise forming ensure tight welding with cylinder bodies, preventing oxygen leakage
Cost Efficiency: Customizable thickness design balances performance and cost, meeting different cylinder grade requirements
Manufacturing Excellence
Produced using advanced cold forming technology to preserve the ductility and weldability of stainless steel, critical for the tight sealing requirements of liquid oxygen cylinders. Our hydraulic forming equipment ensures compliance with GB/T 25198 and ASME standards, delivering smooth, uniform surfaces that prevent stress concentration and reduce potential risks in cryogenic operations.
Quality Assurance
Inspection: 100% full inspection, including UT (Ultrasonic Testing), PT (Penetrant Testing), and 3D laser scanning, to ensure no defects in the head structure
Standards: GB/T 25198-2023, ASME BPVC Section VIII Division 1, PED 2014/68/EU—meeting global safety standards for cryogenic pressure vessels
Certifications: ISO 9001:2015, ISO 14001:2015, ASME "U" Stamp—guaranteeing product quality and compliance
Industrial Applications
Specialised in liquid oxygen cylinder manufacturing:
Cryogenic storage: Upper outer layer component of liquid oxygen cylinders, ensuring leak-proof and pressure-resistant performance
Industrial gas equipment: Compatible with liquid oxygen storage and transportation vessels, adapting to low-temperature (-183℃) working conditions
Medical/industrial oxygen systems: Reliable component for oxygen cylinder production, meeting strict hygiene and safety requirements
Henan Guojiang maintains strict quality control from raw materials to finished products. Our 550mm diameter dished head for a liquid oxygen cylinder (the upper part of the outer layer) delivers stable performance and reliable quality, enhancing safety in cryogenic oxygen storage and transportation applications.
