This EHA-type ellipsoidal head (specification 3800ID × 18 thickness, material S31603) is a core pressure-bearing and sealing component for cryogenic transportation equipment and industrial pressure vessels, manufactured via the cold pressing process. The standard 2:1 major-to-minor axis ratio ellipsoidal structure with a straight edge optimises the flow path of low-temperature media, reduces fluid stagnation in the vessel, and can adapt to harsh working conditions from -60℃ to normal temperature, tailored specifically for the safe and efficient operation of cryogenic storage/transportation equipment and industrial pressure-bearing devices.
Produced by an enterprise with 12 years of experience in precision head manufacturing, the product quality is recognised by enterprises in more than 10 countries worldwide, making it a preferred choice for cryogenic pressure-bearing components in cross-border supply chains.

Practical Applications
Core Sealing for Cryogenic Transportation Equipment: As the tank end-sealing component for 30-50 cubic meters cryogenic storage tanks/tankers, it is used for long-distance transportation of low-temperature media such as liquefied natural gas (LNG), liquid nitrogen, liquid oxygen, and liquid carbon dioxide. It ensures the tightness of the medium in the tank and reduces volatilisation loss.
Adaptation to Related Industries: Meets the low-temperature storage/transportation and medium-low pressure-bearing needs of the energy, chemical, and pharmaceutical industries. It can be accurately connected with tank anti-wave plates and low-temperature valves, improving the overall pressure-bearing performance and operational safety of the equipment, and adapting to scenarios such as cryogenic logistics, chemical raw material storage/transportation, and pharmaceutical low-temperature storage.
Customization & Assurance
Customisation Service: Personalised ellipsoidal head size, thickness, and surface treatment solutions are available according to the specific volume, medium type, and working condition requirements of cryogenic storage tanks/vessels.
Quality Assurance: Full-process quality traceability, with strict control over each link from S31603 raw material cutting, cold pressing forming to finished product inspection; each product is accompanied by a quality inspection report to ensure compliance with the long-term safe operation requirements of cryogenic equipment and industrial pressure-bearing vessels.
