Our fifteen tube mills are able to form, weld, size and cut steel tubing of any shape to length in one continuous process. Flat steel strips are passed through consecutive matching rolls with contoured grooves, which gradually form the cold steel into a tubular shape.

The butted edges of this steel tube are then welded along the entire tube length by a highly-refined welding process. This welding procedure is critically controlled to assure consistent, uniform quality and ultimate weld integrity.

Next the flash created in welding is removed from the outside diameter of the tube with a cutting tool that is contoured to the diameter of the tube being formed. When customer specifications require, Hofmann also has the capability to flash-roll the inside diameter to smooth the inside tube surface.

Following flash removal, the welded tubing, which is always produced slightly oversized, is rolled to acceptable OD tolerance in the final sizing operation.

When producing tube shapes other than round, one more forming step is employed. The finished round tube is reshaped through a series of Turkshead rolls to form square, rectangular or oval tubes.

In the last stage of the continuous tube mill, the finished tubing is automatically measured and cut to desired length.

Slitting
Hofmann's in house, high speed slitting operation provides the control and flexibility for superior tube mill scheduling to meet our customer's requirements.

Our slitting operation features: automatic edge trim; 3 multiple cut heads for quick knife changes; 30-foot loop pit to allow for small variances in coil crown; full tension stand unit; and full, 3-mode method of operation - pull-through, slitter assist, and loop.
