Carbon Steel Elliptical Head 2280mm Inner Diameter 16mm Thickness Ellipsoidal Head

1. Core Specifications

• Key Dimensions: Inner diameter 2280mm, nominal thickness 16mm, adopting standard ellipsoidal structure (major-to-minor axis ratio 2:1) with straight edge to optimize weld stress distribution.
• Material & Connection: Made of high-quality carbon steel, formed by welding 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 ASME codes, suitable for medium and low pressure working conditions.

2. Process & Performance Advantages

• Forming Process: Adopts hot press forming combined with step-by-step stamping to avoid wrinkling and uneven thickness, followed by heat treatment for structural stability.
• Welding Quality: Welds undergo MT (Magnetic Particle Testing) or PT (Penetrant Testing), free of cracks, pores and other defects, with weld joint strength matching the base material.
• Mechanical Properties: Uniform stress distribution on the ellipsoidal surface, superior to dished heads. 16mm thickness design withstands medium-low pressure loads, compatible with various industrial media.

3. Practical Applications

• Petrochemical industry: End sealing of large oil storage tanks and medium buffer tanks;
• Energy & power sector: Heat exchanger and thermal storage tank head components;
• General machinery industry: Closed-end covers for pressure vessels and reactors.

4. Quality Assurance

• Full-process quality control: Traceable from blank cutting, welding forming to finished product inspection;
• Factory inspection: Each product passes dimensional accuracy verification and non-destructive testing, with quality report provided.
