Nominal pipe size (NPS) is the number that defines the size of the pipe. For example, when you say 6" pipe, the 6" is the nominal size of that pipe. However, for the pipe sizes, NPS 14 and above Outside Diameter is the same as NPS. To understand this concept, you have to learn the way pipes are manufactured. Manufacturing of NPS ⅛ (DN 6 ...

In the tube mill, flat steel strip (1) is formed continuously around its longitudinal axis to produce a round tube. This is done by moving the strip through a progressive set of rolls (2-6). The strip edges (7) are heated by either high frequency induction or contact welding and then forged together by weld rolls to create a continuous ...

Semi-finished billets, blooms, beam blanks and slabs from the continuous casting process are transformed into a variety of construction products by various processes of heating and mechanical working. The resulting products are either used directly in fabrication of steel components, that are subsequently assembled into structures on site, or made into further …

The design options we use are usually a result of collaboration between the roll designer and the roll buyer which should also include shop floor management and/or mill operator preferences. Technical considerations always include the physical properties of the metal being formed, the tube size with respect to mill size, and the mill configuration.

The square layouts are required where it is necessary to get at the tube surface for mechanical cleaning. The triangular arrangement allows more tubes in a given space. The tube pitch is the shortest center-to-center distance between tubes. The tube spacing is given by the tube pitch/tube diameter ratio, which is normally 1.25 or 1.33.

For tube less than about 1.0 OD, and a two-roll box, the recommended shape is shown in Fig. 4-4. This is the optimum shape. It gives the best weld quality and highest weld speed. Above about 1.0 OD, the .020 offset becomes insignificant and may be omitted, each roll being ground from a common center.

You can successfully roll-form a profile more than one way. In fact, many roll form designers take different approaches to design and development. Also, because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables, many roll form designs are one-of-a-kind; therefore, theory can go only so far.
