10 MANDREL MILLS AND MPM Sound solutions since 1972 The continuous rolling process – using mandrel mills – has been successfully used as a method of producing seamless steel tubes since the 1970s. The mandrel mill comprises several 2-roll stands which roll the hollow longitudinally to form a shell.
Chromium-plated mandrel plays a very important role in the mandrel mill process. The Mandrel is the important tool for MPM or FQM during seamless tube production .When rolling seamless tubes, a pre-pierced steel billet is rolled over a mandrel bar by grooved rolls in a stretch reducing rolling process to produce a tube or a tube blank.
This plant produces seamless tubes to close tolerances. It will enable Tenaris to meet the increased demand for precise, high-strength tubes, e.g. for shale gas extraction in the USA. Included in the core components supplied by SMS are: Barrel-type piercing mill with Diescher discs ; 6-stand PQF ® BCO retained mandrel mill; 4-stand extracting mill

Rolling mills based on three rolls have been developed which are more tolerant of material quality. The second stage in producing seamless steel tubes is to locate the rough tube onto a mandrel and roll it to reduce its wall thickness. A Pilger mill is …
Mandrel Mill Process. In the Mandrel Mill Process, a solid round (billet) is used. It is heated in a rotary hearth heating furnace and then pierced by a piercer. The pierced billet or hollow shell is rolled by a mandrel mill to reduce the outside diameter and wall thickness which forms a multiple length mother tube.
A mandrel mill is provided which can perform elongation rolling with a markedly increased working ratio and dimensional accuracy on a material which is inherently difficult to roll such as a hollow shell made of stainless steel or a thin-walled material. A mandrel mill for manufacturing a mother tube by performing elongation rolling of a hollow shell comprises a plurality of roll …
In the seamless pipe rolling process, the pipe wall thickness is largely determined at the mandrel mill or plug mill. It is possible to obtain the target thickness at these mills by defining the gap of a grooved roll and an inside tool such as a plug. However, the thickness of the free deformation part, which is not in contact with the roll and tool, had generally been estimated by ...
