Copper scrap for tube-making is most often in the form of recycled copper wire that has been stripped of its insulation and/or baled copper tube that has been removed from demolished buildings. Another common form of scrap is the so-called "home" or "runaround" scrap generated within the tube mill itself.
PIERCING (ROTARY FORGING) Piercing a seamless steel tube is a forging operation in which the metal is worked from the inside as well as the outside. We convert a solid bar into a hollow shell by displacing material over a mandrel during rotary rolling. This process results in a refined grain structure and uniform grain flow.
Rotary tube piercing, also called roll piercing, or the mannesmann process, is a hot forming process that can manufacture long lengths of seamless tube and pipe. Compressive forces applied to a cylinder will create internal stresses at the center. These stresses result in crack propagation. Figure:152 ...
The pipe was finished by passing it through a groove and rolling mill. Russell's method was not used long because in the next year, Comelius Whitehouse developed a better method for making metal tubes. This process, called the butt-weld process is the basis for our current pipe-making procedures.
HOT FINISHED Hot finished mechanical tubing is produced by rotary piercing, plug, or Assel mill rolling, and final processing through multiplepass sizing-reducing mills. Tolerances and finish are similar to other hot worked steel products. Range of sizes and grades is more restricted than cold finished by the nature of the process involved.
Ring Rolling Ring rolling is a particular category of metal rolling, in which a ring of smaller diameter is rolled into a precise ring of larger diameter and a reduced cross section. This is accomplished by the use of two rollers, one driven and one idle, acting on either side of the ring's cross section.

Tube Rolling the production of seamless metal pipe and tubing by rolling on special mills, called tube-rolling units. Seamless pipe and tubing—by which is meant products without longitudinal or spiral welded seams—is widely used in the manufacture of automobiles, tractors, aircraft, and boilers. It is also used in various other branches of the ...
This process uses a piercing mill, which is a skew rolling mill for piercing in cylindrical billets. While rotating the billet with a pair of skew rolls, the piercing mill presses the billet against a plug to pierce the billet, and then rolls the billet between rolls and the plug, forming it into a hollow tube .
Rotary piercing is a hot working metalworking process for forming thick-walled seamless tubing. There are two types: the Mannesmann process and the Stiefel process. ... The formed tube is then cooled and can be cold worked to refine the diameters and to achieve the desired yield strengths. Mannesmann mills can produce tubes as large as 300 mm ...
The pierce-rolling process, which was patented in 1886, made it possible for the first time to roll a thick-walled seamless hollow body from a solid steel billet.. To do this, the billet is heated to between 1200 and 1300°C and then positioned between two rolls arranged at an angle to each other and operating in the same direction, thus locking the billet into a kind of gear mechanism.
Hot Finished Seamless (HFS) as differentiated from Cold Drawn Seamless (CDS) pipes and tubes are made by heating a solid billet or bloom and then punching or piercing it to make a hollow out of it. This hollow is subsequently passed through one or multiple stands with or without a tool inside to give it the final pipe or tube dimensions.
