Dished and Spun Heads
Our dishing and spinning equipment enables us to cold form heads up to 1 1/4" (31.75 mm) x 28'-6" (8687 mm) in diameter. Hot dishing and spinning allow us to manufacture heads up to 2 3/4" (69.85 mm) thick.

Semi-Elliptical Heads: from 96" (2,438 mm) O.D. to 288" (6,096 mm) O.D.

Heads can be formed from our own plate inventory, from special material we order in (eg. clad plate), or from customer supplied material.

Carbon steel and chromium molybdenum heads are delivered in the as-formed condition. Stainless steel and clad heads are delivered in the pickled or sandblasted condition.

Edmonton Exchanger can supply heads either "untrimmed" or "trimmed and beveled" (single or double bevel) as per client requirements.

All heads are formed to ASME standards, and are accompanied with appropriate documentation consisting of Inspection Reports and Mill Test Certificates. ASME approved forming procedures, heat treating procedures, furnace heat charts, and dimension reports are available upon request.

Pressure Vessel & Tank - Head Forming
With our 1,200 ton and 3,000 ton head presses (designed and constructed by Edmonton Exchanger), we are able to hot form heads up to 192" (4,877 mm) I.D. and up to 8" (203.20 mm) thick.

Semi-Elliptical Heads: from 8 5/8" (219 mm) O.D. to 192" (4,877 mm) I.D.

ASME Code Flanged and Dished Heads: from 48" (1,219 mm) I.D. to 96" (2,438 mm) I.D.

>> Torispherical Head Specs. (PDF)

Hemispherical Heads: from 8 5/8" (219 mm) O.D. to 144" (3,658 mm) I.D.

>> Hemispherical Head Specs. (PDF)

Flanged Only Heads: from 31" (787 mm) O.D. to 76" (1930 mm) I.D.

Dished Only Heads: from 10" (254 mm) O.D. to 120" (3,048 mm) O.D.

We will construct dies for special head shapes upon request.

Typically, carbon steel heads are hot formed at 1,650 degrees Fahrenheit (899 degrees Celsius). Stainless steel heads are hot formed at approximately 1,900 degrees Fahrenheit (1,038 degrees Celsius).

Chromium molybdenum steel heads are usually hot formed at 1,650 degrees Fahrenheit (899 degrees Celsius) and tempered at 1,350 degrees Fahrenheit (732 degrees Celsius).

Clad heads are formed at temperatures suitable to the material. Various forming temperature requirements and additional heat treatments can be accommodated upon request.
