Pressure Vessel Components
Hot Pressed Heads We are able to hot press heads up to 192” (4,877 mm) I.D. and up to 8” (203.20 mm) thick with our 1,200 ton and 3,000 ton head presses. Each press was custom designed and constructed by Edmonton Exchanger. Semi-Elliptical Heads: from 8⅝” (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. Hemispherical Heads: from 8⅝” (219 mm) O.D. to 144” (3,658 mm) I.D. Flanged Only Heads: from 31” (787 mm) O.D. to 76” (1,930 mm) I.D. (various dies available, can custom build dies for a specific size) Dished Only Heads: from 10” (254 mm) O.D. to 120” (3,048 mm) O.D. 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 usually hot formed at 1,650°F (899°C) and tempered at 1,350°F (732°C). Clad heads are formed at temperatures suitable to the material. Various forming temperature requirements and additional heat treatments can be accommodated upon request. Dished and Spun Heads Our dishing and spinning equipment enables us to cold form heads up to 1¼” (31.75 mm) x 342” (8,687 mm) in diameter. Hot spinning allows us to manufacture heads up to 2¼” (57.15 mm) thick. Semi-Elliptical Heads: from 96” (2,438 mm) O.D. to 288” (6,096 mm) I.D. ASME Code Flanged and Dished Heads: from 96” (2,438 mm) O.D. to 342” (8,687 mm) I.D. 80:10 Flanged and Dished Heads: from 90” (2,286 mm) O.D. to 330” (8,382 mm) I.D. Flanged Only Heads: from 72” (1,829 mm) O.D. to 168” (4,267 mm) I.D. Dished Only Heads: from 120” (3,048 mm) O.D. to 360” (9,144 mm) O.D. Heads can be formed from our own steel plate inventory, from special material we order in (such as clad plate) or from customer supplied material. 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. Edmonton Exchanger can supply heads either “untrimmed” or “trimmed and beveled” (single or double bevel) as per client requirements. |
