The Yoder “Hot Sizer” Hot Sizing Mill System consists of multiple stands to reduce and re-round API pipe which has been immediately heat treated. The Hot Sizer is customized based on the amount of work required from the Customer’s specifications. The Yoder Hot Sizer is accustomed to experiencing pipe temperatures as high as 1100˚ F and can handle speeds up to 200 FPM. Quick-change as well as special drive arrangement options are available to help our Customer’s experience high throughput on their heat treating finishing floors.

In response to the increasing world wide demand for small diameter (i.e., 0.188″ to 0.375″ OD) steel tube for both refrigeration and automotive purposes, Yoder can provide equipment for production of these tubes. Since 1992, complete Yoder Cold-Stretch Reduction Small Diameter W-10 / W-15 Tube Mill Systems have been supplied to Turkey, China (2 lines), South Africa, and the United States. This U.S. line may be the first new mill of its type installed domestically in the last fifteen years.
Yoder has been involved with the pipe producing market for many years. Cutoffs have evolved from rotary disc or tool machines to friction saws to the latest saw technologies. Milling saws provide a fantastic edge finish with minimum burr but tend to have longer cycle times. Formtek works with its licensee Milltech to provide the pipe mill markets the highest quality with the greatest performance. Milltech has developed mill cutoff systems utilizing 2-heads or 4-heads (depending on pipe size) to provide the best combination of end finish and cycle time performance. These machines are designed to handle the heavy strains put on them by the demanding cycles required by our customers.
Yoder has long been recognized as one of the earlier pioneers in the welded seam tube mill business. Yoder Tube and Pipe Mill Systems include multiple standard tube mills for common product sizes. In addition to the standard machines, Yoder also offers specialized equipment that covers a huge diameter range of metal tubes and pipes; from the 3/16″ (4.76mm) O.D. cold stretch reducing mills to the 28″ OD cage mills. As required by the application for welding the tube or pipe, Yoder can provide mills with high-frequency induction or contact welders, DC & AC Square Wave Welding (ERW), TIG and laser.
For Tube and Pipe manufacturing, Yoder provides a range of solutions to fit the application: complete mills, individual machines, mill accessories, tooling, as well as well as consulting, engineering studies and retrofits to existing installations.
Yoder Tube Coilers are available in two and three basket configurations for recoiling small diameter single wall and double wall tubing, used in fuel lines, refrigeration, and brake line applications.
The Yoder Universal Cage Forming System, originated and patented by Yoder, is based on sound mathematics and unique concepts. This method becomes more desirable and essential as the ratio of the pipe outside diameter to wall thickness (i.e., D/t ratio) exceeds 40:1, and up to 100:1 range. More conventional forming methods roll material in discrete steps or passes and employ brute force. The Yoder Cage System forms the strip continuously with smooth transitions and minimum effort. Hence, the material is actually guided through the forming mill with uniform but infinitesimal change of shape in each small increment of pipe travel.
The buckling of strip edges in light wall pipe has been a shortcoming of the conventional pipe mill. This is problem is even more evident now that higher yield strength materials are allowing pipe producers to decrease the wall thicknesses (and pipe weight) further, thus increasing the D/t ratio even more.
