PRODUCTION PROCESS

Heat treatment

Over the years, as Ringmill has acquired the expertise to work with a vast array of steels, from simple carbon steel to the most sophisticated alloys, important investments have been made in furnaces and quenching tanks.

In particular, for heat-treating pipe a special device was developed to rotate the pieces while tempering in order to reduce deformations to a minimum and, at the same time, improve the internal and external quality of the piece.
