Product Description

2:1 Elliptical Dished Tank Heads With Reduced Opening Stainless Steel

2:1 Stainless Steel Elliptical Dished Head with Reduced Opening (1050*6)

Basic Product Information

Core Parameters

Model Specification: Stainless Steel Elliptical Dished Head with Reduced Opening EHA1050*6 (SUS304/SUS316L), featuring high strength and corrosion resistance, suitable for medium and large pressure-bearing equipment.
Dimension Details: Standard inner diameter 1050mm, compatible with medium and large storage tanks and pressure vessels in chemical, new energy and other fields; the size of the reduced opening can be customised (ranging from 80mm to 250mm).
Thickness Specification: Nominal thickness 6mm, optimising load-bearing while ensuring structural stability, suitable for working pressures of 0.2MPa-12MPa.

Material Selection

Mainstream stainless steel materials: SUS304 (versatile, corrosion-resistant), SUS316L (resistant to strong acids and alkalis).
Customizable optional materials: Carbon steel (Q235B, Q345R), duplex steel (S31803).
All stainless steel materials are sourced from certified suppliers with complete Material Test Certificates (MTC).

Core Product Advantages

Excellent Corrosion Resistance: The dense oxide film on the stainless steel surface can resist corrosion from the atmosphere, acid and alkali media.
Integrated Reduced Opening Design: Eliminates the need for secondary welding of pipe connections, reducing the risk of leakage.
High Strength and Stability: The elliptical structural design evenly disperses internal pressure, enhancing overall pressure resistance.

Forming and Surface Treatment

Forming Process

Cold Forming: Preferred for 6 mm-thick stainless steel plates, maintaining original mechanical properties.
Hot Forming: For stainless steel with a thickness of≥12mm or high-strength alloys, with heating temperature controlled at 850℃-1050℃.

Surface Treatment

Chemical Polishing: Achieves a surface roughness of Ra ≤ 1.6μm, reducing medium adhesion.
Electrolytic Polishing: Creates a mirror effect (Ra ≤ 0.8μm), improving surface finish.
Passivation Treatment: Strengthens the surface oxide film, enhancing resistance to harsh media.

Inspection Standards

Ultrasonic Testing (UT): 100% coverage to detect internal inclusions and defects.
Penetrant Testing (PT): Detects surface and near-surface cracks and pinholes.
Dimensional Inspection: Verifies key parameters using high-precision measuring equipment.
Pressure Testing: Sampling pressure tests of 1.5 times the rated pressure.
