The piercer point is a high-temperature, water-cooled alloy tool designed to allow the metal to flow over it as a pipe shell forms from the rotary process. Once the pierced pipe shell is produced, it is immediately transferred to the floating mandrel mill. The floating mandrel mill comprises eight rolling stands using 16 rolls and a set of ...
1. Seamless Pipe. Mandrel Mill. ->This process is used to make smaller sizes of seamless pipe, typically 1 to 6 inches (25 to 150 mm) diameter. -> The ingot of steel is heated to 2,370 °F (1,300 °C) and pierced. -> A mandrel is inserted into the tube and the assembly is passed through a rolling (mandrel) mill.
experience or laboratory tests before mill size can be determined. The required mill net power P kW ( = ton/hX kWh/ton) is obtained from. P = const. x c x q x nc x Li x Di2.5; where an approximate figure for the constant is 3.5 for rod mills, 4.0 for overflow ball or pebble mills and 4.5 for grate discharge ball or pebble mills.

An exacting process that leaves nothing to chance. The creation of U. S. Steel seamless steel pipe begins with solid steel rounds, or billets, cut to a specified length. They are then sent through a walking-beam reheat furnace, where temperatures reach nearly 2,300 ° F. The pieces are then sent to the rotary piercing mill where the rounds are cross-rolled between two barrel-shaped …

The billet enters the rotary piercing mill where a pneumatic ram feeds the billet between heavy rollers that drive it over a piercing point, producing a tube hollow. While still hot, the tubes or pipes are reduced in size in a stretch reducing mill, which produces shells.

There are five main criteria for determining the design of the Rotary Sizing Mill. They are tube diameter, diameter range, wall thickness, yield strength and mill speed. Analysis of the tube diameter, wall thickness and yield strength are required to determine the number of rollers and the size of the rollers required.
The Yoder W-15-S Cold Reducing Tube Mill System welds a tube up to 1.25″ (31.8 mm) diameter and can produce finished diameter down to 3/16″ (4.76 mm) diameter. Wall thicknesses range from 0.020 to 0.040″ (0.05 to 1.0 mm) but applications up to 0.060″ (1.5 mm) have also be done.
seamless tube mill After dozens of installations of Piercing Mills, Rotary Expanders, Sizing Mills / Stretch Reducing Mills, Pipe Straightening Machines, Hot Pilger, Accu and Assel, China has emerged as a more and more important supplier for 2-roll retained mandrel mills (MPM) and 3-roll retained mandrel pipe mills.

Machine for in-line tube end deburring by means of metal tools making the automatic inside and outside removal of burr. This equipment is used for tubes from 10 to 76 mm O.D., it is directly mounted on the unloading table of the mill and the tube movements are fully automatic.
Further reductions in the seamless pipe wall thickness and increases in overall pipe length are gained by passing the pierced billet through the plug rolling mill. Pipes larger than 16" OD are reheated and sent through a rotary rolling mill, which uses large discs to expand the hot tubes up to 26" in diameter .
Tube classification goes out several aspects: mode of produc-tion, cross section shape, tube ends treatment, sphere of tube usage. According to EN 10079 tubes rank among so-called long prod-ucts. It is a product having permanent circular or another hollow section along, with both ends free and with relatively long length.
available. For example, pipe and structural tubing may often be inter-changed, or a hydraulic tube may be used for a mechanical application. For critical applications, though, especially when governed by the specifications, care should be taken to insure that the tube ordered possesses the necessary properties. Sec. K page 1 pages 3-96

The pipe passes through sizing section where the outer dia is maintained & pipe straightened with the help of Turk Head. The required length is cut on cut off carriage on line without stopping the mill. The cut length pipe is rolled out on conveyor & stopped by stopper at end of Conveyor and ejected to the pipe collecting pockets.
