Head Forming

Hot Pressed Heads Formed with Custom-Designed Presses

No matter what size and thickness of head you have, we can make it! That’s why we created two custom-designed head-forming presses to handle your project needs: A 1,200- ton head press, and a 3,000-ton head press. We can hot press heads up to 192” (4,877 mm) I.D. and up to 8” (203.20 mm) thick, so whatever the challenge, we say bring it on!

Semi-Elliptical Heads

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

ASME Code Flanged and Dished Heads

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

Hemispherical Heads

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

Ed Ex Facts: Head Temperatures

  • Typically, carbon steel heads are hot formed at 1,650°F (899°C).
  • Stainless steel heads are hot formed at approximately 1,900°F (1,038°C).
  • Chromium molybdenum steel heads are hot formed and tempered as specified by MTR.
  • Clad heads are formed at temperatures suitable to the material.
  • Various forming temperature requirements and additional heat treatments can be accommodated upon request.

 

Head-Forming Flexibility with Materials

Heads can be formed from our own steel plate inventory, from special material we order in (such as clad plate), or from material that you supply.

Untrimmed Heads, Trimmed and Beveled Heads

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

Delivered: As-Formed, Pickled, Sandblasted

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