Product Description

Product Overview

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.
