We fabricate, trial fit, tack weld, match, mark and knock-down our tank heads with robotically trimmed, tapered or beveled edges.
Whether from normalized or as-rolled plates, our segmental tank head types range from Semi Elliptical, Flanged and Dished, Tori-conical, Double Knuckle Cone, Toroidal, Hemispherical and Dished Only.Our fabrication of Segmental, multi piece, tank heads go back 60 years, and our experience and precision allow us to produce the highest quality segmental heads ready for fit up, with no need for additional work.
Our in-house robotic trimming allows for faster production while maintaining a high level of accuracy. We have two technologically advanced robotic rooms to take care of precision trimming and beveling.
In some cases of thin or extremely thick Hemi’s or multi curvature structures a segmental is your only solution. Ask for examples of some of our more difficult projects.
Our commitment to innovation and continuous improvement, allows us to stay ahead of industry demands and provide the quality and precision that our clients have come to expect.
