Tube rolling plants with plug mill are intended for production of hot-rolled seamless tubes of different diameters, wall thickness (both thin-walled and thick-walled), steel grades and alloys (including stainless and hard-deforming).
Finished tubes are used in civil engineering, machine building, oil and chemical industry, in special production. Tube plants with plug mill allow to transfer rapidly from one kind of tubes to another which predetermines their efficiency. The plants are completely mechanized and maximum automated.
