Five Sets of Plate Rolls = Shells, Rolled Rings, Cones, Repads

With our selection of five sets of plate rolls, we can provide you with plate rolled into shells, rolled rings, cones (both eccentric and concentric), or repads. These components can be rolled from our own plate inventory or from material that you supply.

Dimensional Rolling Capacities

  • Minimum Diameter: 16” (406 mm) I.D.
  • Maximum Thickness: cold rolled 8” (203.20 mm), hot rolled 12” (304.80 mm)
  • Maximum Length: 144” (3,658 mm)

Shells Rolled to ASME Specifications

Shells are rolled to ASME code specifications and rolled to our own head strappings.

Square Cut, Beveled Circumferential and Long Seam Shells

We can supply you with square cut or beveled circumferential and long seam shells. Long seams can be provided tack welded or fully welded. We can also provide welded circumferential seams by welding together multiple courses.

Mill Test Certificates/Furnace Heat Charts

Components rolled from our plate inventory are accompanied with Mill Test Certificates. In the case of hot rolled items, Furnace Heat Charts can be provided upon request.

Concentric Cones: One Piece, One Seam

Concentric cones can be rolled up to a thickness of 4” (101.60 mm) and a length of 10’-0” (3,048 mm). Diameters can be from 24” (610 mm) O.D. to 168” (4,267 mm) O.D. They are rolled in one piece with only one long seam when plate layout allows it. We can provide you with cones that are square cut or beveled with long seams tack welded or fully welded.

Eccentric Cones

Eccentric cones can be rolled up to a thickness of 1” (25.40 mm) and a height of 48” (1,219 mm). They are rolled in one piece with only one long seam when plate allows for it. Eccentric Cones are supplied with long seams tack welded or fully welded.

Nondestructive Examination/Inspection Forms

Fully welded shells and cones come complete with necessary nondestructive examination and the applicable inspection forms.
