Cold Pressing1700mm ID 6.5mm Thick Ellipsoidal Head– Cryogenic Tanker Matching

1. Core Specifications

Key Dimensions: Inner diameter 1700mm, nominal thickness 6.5mm, adopting standard ellipsoidal structure (major-to-minor axis ratio 2:1) with straight edge to optimise weld stress distribution.
Material & Connection: Made of low-temperature resistant special steel, manufactured by a cold pressing process. Groove and weld areas are ground and residual stress relieved, with butt misalignment ≤10% of material thickness.
Standards Compliance: Conforms to GB/T 25198 and relevant low-temperature equipment standards, suitable for the working environment of cryogenic tankers from -40℃ to normal temperature.

2. Process & Performance Advantages

Forming Process: Full cold pressing forming, combined with step-by-step stamping technology, to avoid material deformation due to overheating, ensure uniform thickness without wrinkles, and maintain structural stability without additional heat treatment after forming.
Quality Testing: Welds undergo PT (Penetrant Testing), free of cracks, pores and other defects. Weld strength is consistent with the base material, meeting the requirement of repeated pressure fluctuations during cryogenic tanker filling.
Mechanical Properties: Uniform stress distribution on the ellipsoidal surface, superior to dished heads. The 6.5mm thickness design can withstand the working pressure of cryogenic tankers, compatible with low-temperature media such as liquefied natural gas and liquid nitrogen.

3. Practical Applications

Cryogenic Tanker Dedicated: As a sealing component at both ends of the cryogenic tanker tank, it is suitable for tankers with a volume of 20-30 cubic meters, used for the transportation and storage of low-temperature media such as liquefied natural gas and liquid carbon dioxide.
Matching Adaptation: It can be accurately connected with the anti-wave plate and manhole assembly of the cryogenic tanker, meeting the overall sealing performance and structural strength requirements of the tanker, and reducing the medium volatilisation loss during transportation.

4. Quality Assurance

Full-process Control: From raw material cutting, cold pressing forming, and welding to finished product inspection, each link is traceable to ensure product consistency.
Factory Inspection: Each product passes dimensional accuracy verification and low-temperature sealing test, and a quality report is provided with the goods to ensure the safe operation of the equipment.
