2020.12.4 Mannesmann Plug Mill Process. In the Plug Mill Process, the material is used. It is heated in the rotary hearth heating furnace and then cut by a Mannesmann piercer. The hollow shell is rolled and reduced in the outside area and wall thickness. The rolled tube simultaneously burns inside and outside by a reeling machine.

Mannesmann Plug Mill Manufacturing Process. This method was founded by Mannesmann, a German engineer. It starts with a cylindrical steel billet, which is pierced and fed between two rollers. At the same time, a cone-shaped mandrel is inserted into the billet. After being pierced, the billet undergoes another rolling stage in which it is elongated.

Unlike the latter, however, the Mannesmann plug mill process will slowly reduce the pipe’s diameter to get the desired one rather than achieve it in a single pass. As such, more thickness reduction and pipe smoothness are achieved in this

The rotary piercing process (Mannesmann proces) is widely used in the manufacture of seamless steel tubes. The process comprises steps of passing billet heated to the prescribed temperatures through a rotary piercer to make them into hollow shell, rolling the hollow shell by mean of an elongator, e.g. plug mill or mandrel mill, to the desired wall
