Ellipsoidal Head- 3300*9 S30408

Product Overview

This ellipsoidal head (specification 3300*9, material S30408) is a core pressure-bearing and sealing component for cryogenic tanker tanks, manufactured via the cold pressing process. Its standard ellipsoidal structure (major-to-minor axis ratio 2:1) with a straight edge optimises the flow path of low-temperature media, reduces fluid stagnation in the tank, and adapts to the harsh working conditions of cryogenic tankers from -40℃ to normal temperature.

Produced by Henan Guojiang Precision Formed Head Co., Ltd., which has over 12 years of experience in precision head manufacturing, the product quality is recognised by enterprises in more than 10 countries worldwide, and it is specially designed for the safe and efficient operation of cryogenic tankers.

Practical Applications

Core Sealing for Cryogenic Tankers: As the tank end-sealing component for cryogenic tankers with a volume of 20-35 cubic meters, it is used for long-distance transportation of low-temperature media such as liquefied natural gas (LNG), liquid nitrogen, and liquid carbon dioxide. It ensures the tightness of the medium in the tank and reduces volatilisation loss.
Adaptation to Related Industries: Compatible with low-temperature transportation needs in the energy and chemical industries, it can be accurately connected with tanker anti-wave plates and low-temperature valves to improve the overall pressure-bearing performance and operational safety of the tanker, adapting to scenarios such as low-temperature logistics and chemical raw material transportation.

Customization & Assurance

Customisation Service: Customised ellipsoidal head sizes and surface treatment solutions are available according to the specific volume and medium type of the cryogenic tanker.
Quality Assurance: Full-process quality traceability, with strict control over each link from S30408 raw material cutting, cold pressing forming to finished product inspection; each product is accompanied by a quality report to ensure compliance with the long-term safe operation requirements of cryogenic tankers.
