The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a circular cross section by funnel arrangements or rolls, and then butt or lap welded in the same heat (forge welding process).

A temper mill is also used to make cold rolled after annealing to assure a consistent quality. After the material is made hot rolled, it needs to be pickled and cold reduced. Cold reducing increases the yield strength and the material can be too hard to be used for any type of deep draw work or accurate bending.

When the traditional method based on the diameter-reducing rate, which does not take the wall thickness into account, was used to distribute the deformation amount of the tube, some adverse influences were introduced to the quality of the finish-tube and the stability of the rolling mill. A new pass designing method on the basis of elongation rate was …

number of passes of the stretch-reducing mill depends on the total size of the reduction and the decrease of the temperature in all the reducing passes. The model design of the stretch-reducing parameters, mainly reductions, stretchings, and temperature, is relatively complex and depends on several mutually related parameters.
