Dish ends and head plates
Pressed dish ends for boilers, high-pressure vessels, storage tanks and heat exchangers — to international standards or customer specification.
Dish Ends & Head Plates
AIMCON is a recognized specialist in pressed dish ends with four decades of experience, producing all types for boilers, high-pressure vessels, processing vessels, road tank bowsers, storage tanks and heat exchangers.
We form MS, CS, SS, nickel alloys, aluminium and specialized steel alloys, with hot and cold forming, on our own dish head flanging and pressing equipment.
Head types & limits
Specifications as published in the AIMCON company profile. Every item can be built to your drawing and code.
| Head type | Limits | Typical use |
|---|---|---|
| Semi-Elliptical Head (2:1) | Dia up to 4,000 mm · thick up to 20 mm | Most widely used vessel head — optimal balance of structural efficiency and ease of manufacture. |
| Semi-Elliptical Head (1.9:1) | Dia up to 4,000 mm · thick up to 20 mm | Elliptical head variant for pressure vessel and tank applications. |
| Torispherical Head | Dia up to 4,000 mm · thick up to 20 mm | Cost-effective for process vessels, storage tanks and low-pressure applications. |
| Standard Dish Head | Dia up to 4,000 mm · thick up to 20 mm | For atmospheric and low-pressure storage vessels and road transport tankers. |
| Flat Head | Dia up to 4,000 mm · thick up to 20 mm | For bolted or flanged flat-end closures, man-way covers and clean-out ports. |
| Semi-Elliptical Segmental (2:1) | Dia up to 12,000 mm · thick up to 40 mm | Large-diameter segmental heads for bulk storage tanks. |
| Hemi-Spherical (Multi-Piece) | Dia up to 12,000 mm · thick up to 40 mm | Very large diameter applications, fabricated in segments. |
| Conical Head with Knuckle | Dia up to 4,000 mm · height up to 1,000 mm | For conical geometry vessels with a smooth knuckle transition. |
| Inverted Head | Dia up to 4,000 mm · thick up to 20 mm | Concave-upward for clarifiers, settlers and specific tank designs. |
