Introduction to Seamless Pipe Manufacturing - .

The design of the piercer rolls causes the metal to flow along the roll and over a piercer point as it exits the process. 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 ...

Rolling (metalworking) - Wikipedia

Modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783, a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars. With this new design, mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was the first to ...

TUBE EXPANSION ISSUES AND METHODS · PDF Datei

Mechanical rolling reduces the tube wall by; a) stretching the tube radially, and b) imposing high unit rolling forces that cause the tube to extrude axially. To roll tubes into tubesheets thicker than 2", you must step roll. This is time consuming and requires a tremendous amount of skill. Because mechanical rolling pushes the tube material out the rear of the tubesheet, a very noticeable ...
