Seamless Steel Manufacturing What Are the Techniques
This process closely resembles the mandrel mill process 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 process than that in the mandrel mill process.
