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 ...

6. Mill in misalignment. Tube mill misalignment, poor mill condition, and inaccurate setup account for 95 percent of all problems in tube production. Most mills should be aligned at least once a year. 7. Tooling in poor condition. Operators must know how much life .
Forming/Welding Mill. The forming and welding section is discussed in greater detail later in this article. It consists of vertical and horizontal passes that form the strip into an open tube. The weld area forges the strip into a closed tube and then removes the bead created during the weld. Sizing Mill. This section is also discussed in ...
By expanding the tube inside the tubesheet, swaging ensures that the space between the two components is always forced closed. Hydraulic expansion is the direct application of high internal pressure within a tube or sleeve in order to form a tight joint between the tube and tube sheet or a tight seal between the sleeve and tube.

The rolling process is shown in Fig. 2.1: Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
spiral pipe, and UO pipe based on the the forming and welding method. ERW pipe and butt-welded pipe are manufactured by continuously forming a hot-rolled coil into a tubular shape by forming mills. ERW pipe is manufactured by cold forming, and the seam is welded by electric-resistance welding. This type of steel pipe is
Oct 10, 2016· Casting is a forming process which converts liquid steel into a solid product. In foundries liquid steel is cast into complex shapes by pouring of liquid steel into a mould in which it sets to the required shape. In steel plants, liquid steel is normally continuously cast in the form of slab (either thick or thin), bloom or billets.

2.1 Seamless pipe manufacturing process 1) The seamless pipe manufacturing process can basically be divid-ed into the Mannesmann rolling process and the press forming proc-ess. The typical Mannesmann rolling process is schematically shown in Fig. 1. This process uses a piercing mill, which is a skew rolling mill for piercing in cylindrical billets.
Metal forming processes Metal forming: Large set of manufacturing processes in which the material is deformed plastically to take the shape of the die geometry. The tools used for such deformation are called die, punch etc. depending on the type of process. Plastic deformation: Stresses beyond yield strength of the workpiece material is required.
Drawing is a metalworking process which uses tensile forces to stretch metal, glass, or plastic.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.
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.
