Drawing is a metalworking process which uses tensile forces to stretch metal or glass.As the metal is drawn (pulled), it stretches thinner, into a desired shape and thickness. Drawing is classified in two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis.
Abstract. The finite element method (FEM) is used for simulation of the tube piercing process in Mannesmann mill. The numerical model is described with taking into consideration thermal phenomena in metal during forming.

The welded seam is then passed through a high pressure roller which helps create a tight weld. The pipe is then cut to a desired length and stacked for further processing. Welded steel pipe is a continuous process and depending on the size of the pipe, it can be made as fast as 1,100 ft (335.3 m) per minute.

Mandrel Mill Process. In Mandrel Mill pipe manufacturing process, steel billet is heated to high temperature in the rotary furnace. A cylindrical hollow, which is also known as mother hollow, is produced with the help of a rotary piercer and set of roller arrangement that .
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is ...
Cold roll forming is a method of shaping hard metals, such as steels and stainless steels. Very precise, complex cross-sections can be created, and long lengths of these sections can be consistently reproduced. Along each length, features such as holes, slots, or embosses can easily be added, making the roll forming process a very cost effective method of achieving a strong, -functional ...

Roll Forming a Tube. Now let's roll form the same 2-in.-diameter tube with prepunching. The process requires 10 passes before the welding station, because a typical roll former doesn't have idler stands. Tube and pipe mills use idlers between almost every pass to assist in forming the round.
Roll forming is ideal for OEMs looking to economically produce high volumes of close tolerance parts with a broad range of geometries. Our custom roll forming process converts both ferrous and non-ferrous metals into hardened states that maximize strength, reduce weight and decrease labor costs versus extrusions.
