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).

The Sheet Metal Rolling Machine works according to the principle of three point bending. The rotation of the driven rolls being utilized to feed the metal through the rolls by means of the frictional forces present between the surface of the rolls and sheet. No lubricant is used at its presence interference with the ability to grip.

Strainer uses a perforated plate or screen mesh to remove larger particles from a process stream. The major advantage of a Strainer is that it is reusable. The filter screen is only used once and must be changed when it clogs. The main difference seems to be in diameter of the holes in the media screen also termed as mesh size in case of strainer.
