Elliptical Tank Heads

Designed for medium-pressure tanks, 2:1 elliptical tank heads provide a cost-effective option. These heads require less metal thickness, making them an economical choice for such applications.

Specifications:

  • 2:1 Elliptical Heads

    • 120″ OD x 1-1/8″ Minimum Thickness – SA516-70N

    • 120″ OD x 3/8″ Minimum Thickness – SA516-70N

A 2:1 elliptical tank head is manufactured with a specific contour rather than a set dish or knuckle radius. The dish radius is approximately 90% of the internal diameter, with the head depth being one-quarter of the vessel’s internal diameter. These heads are widely used in pressure vessels.

Haipei Industry offers high-speed, one-stop solutions for cold-formed tank heads, segmented umbrella domes, and spherical shroud gores.

Features of 2:1 Elliptical Tank Heads:

  • Cost-effective for medium-pressure tanks due to reduced material thickness

  • Also known as ellipsoidal heads, comprising two sections: a rotating ellipsoidal sphere and a cylindrical straight portion

  • Type: Cap

  • Shape: Semi-elliptical

  • Materials: Carbon steel, stainless steel

  • Manufacturing: Custom punching available based on client specifications

  • Compliance: ASME standards for carbon steel dished ends in cylindrical pressure vessels

Applications:

Our tank heads are utilized in various industries, including pharmaceutical, chemical, biotech, cryogenic, and more.

Dimensions & Materials:

  • Diameter Range: 89mm to 13,000mm

  • Thickness: 2mm to 400mm

  • Reduction Ratio: Around 10%

  • Materials Available: Duplex steel, carbon steel, stainless steel

Calculation of Overall Head Height:

Overall Height = Internal Diameter + Straight Flange + Material Thickness

We maintain an extensive inventory of 2:1 stainless steel semi-elliptical tank heads, with over 12,600 heads in stock and 3,400 more in production, ranging in size from 12″ to 48″.

FAQ

Q: What’s the information should I provide when inquiry?

A: Thanks for your question. If you have drawings, we will be entirely in accordance with production drawings . If you do not have the drawing, you can tell me the product data. There are several important data, such as material, type of head( We have elliptical head, hemispherical head, dished head, flat head, etc. ),diameter, thickness, special tolerances or requirements. We can do the drawings according to your requirements, and you confirm that the final product drawings.

Q: what are surface treatment of the product?

A:Thanks for your question. For carbon steel products, we sandblasting descaling product surface. For stainless steel products, we use acid to remove surface oil and impurities.

Q: How do you ensure the quality of products?

A: Thanks for your question.Our production staff is trained through national quality department, and obtain the corresponding certificate, with years of production and design experience. Weld must undergo X-ray inspection to ensure that no defects.

Q: Can you help us matching related products?
