Other processing steps, such as rolling the steel into a coil, uncoiling it, and running it through a tube mill (forming the tube and sizing it) deform the steel grains. Cold drawing a tube over a mandrel also stresses the material, as do fabrication steps such as end forming and bending. A change in the grain structure is called a dislocation.

In the classic sense, a tube mill is a kind of welded roll form system; however, not every welded roll form system is a tube mill. Tube mills are welded roll form systems that have been finetuned to run a specific diameter range, typically at fast speeds (see Figure 1 ). Diameter range is mentioned because a tube mill welds a round product.

In an ERW Pipe Mill, the process of manufacturing pipes begins with a coil of steel that is unwound and passed through several forming rolls. These rolls bend and shape the steel into a cylindrical shape with a seam on one side. The seam is then welded together using an electric current to create a continuous, longlength pipe.

Electric resistance welded (ERW) pipe is manufactured by coldforming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material. Initially this manufacturing process used low frequency current to heat the edges. This low ...

adds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll directly below the tube. D eliminates edge misalignment and is especially suited to D/T ratios above 10:1.

Electric resistance welded (ERW) pipe is made from steel coil and the weld seam runs parallel to the pipe. The width of the coil is the same as the circumference of the pipe so diameters are limited to 24 inches. However, because the manufacturing process is fast, it is ideal for large production runs of small (<= 24 in.) diameter sections.
