Plugmill Technology

Plug Mill Process is a proven process for manufacturing of higher diameter Seamless Pipes by heating round billets up to the plastic stage of steel and piercing in a Cross Roll Piercer. Further elongation is achieved through a Plug Mill in which the thick wall hot hollow is rolled through a pair of Top and Bottom Rolls with a plug inside to control the ID and achieve better internal surface finish.

World Class Reelers are used to improve the wall thickness circumferentially, to achieve close tolerance on the Wall Thickness. As the OD and the ID are controlled by external and internal toolings during hot rolling in Plug Mill and Reeler, the pipe will have closer tolerance, to cater to the requirements of OCTG and other applications.
