8KHH ERW Mill Expanded Range (38.1 – 219.1 mm O.D. Range) – Korea 2007

Abbey International Ltd. has recently supplied an entire line 8KHH ERW Mill to make 38.1 mm (1.500”) to 219.1 mm (8.625”) O.D. pipe and tube in Korea essentially servicing the Gas, Oil, and Automotive Industries. This mill also has capabilities of producing pipe and tube in wall thickness from 3.0 mm to 15.9 mm (D/T ratio as low as 6:1).

The line also includes Abbey International’s patented Continuous Cart Transfer (CCT) System for Quick Change, which is designed to receive sub-plated mill sections during changeover of the mill. The forming base incorporates a powered rack and pinion push off and pull back and auto location to accommodate the sub-plated mill stands. With this system, the use of cranes during mill changeover is minimized and a very fast changeover time is possible, thus substantially reducing mill downtime.

Some additional features on this mill includes a High Speed Traveling Rotary Cutoff with pre-bevel capability delivering cut and pre-beveled lengths from the mill exit, 1000 kW induction welder with unique weld pass is followed with 2000 kW seam annealing power and a special air cooling section. The mill was also designed to run downhill to drain the mill coolant and eliminate the potential for stream build as a result of the heat introduced at the seam annealers

This entire line was 250 meters long, and was completed in 16 months
