Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.
Roll Tooling Design – Standard Edgeform Method The standard edgeform method of tooling design is the most widely used in the tube and pipe industry. This method is used to form a wide range of materials and gauges from mild steel to higher tensile (tension).
Tube Roll Design - JMC Rollmasters Tube Roll Design Tube roll design is an organized process culminating in the production of a roll formed welded metal tube. First consideration is the products' specific characteristics of size, shape and physical properties. The next consideration is the forming and welding machinery available to the producer.

It's also called a roll stand, or one pass in the roll forming process. Each stand has a set of two rolls with spacers that align the roll horizontally along the shaft. The space between the rollers, usually set at the material thickness being processed, is the roll tooling gap .
Design the Layout and Roll Tooling. After completing the flower, you need to choose drive diameters and check for maximum flange roll sizes and possible interference with the rolling mill. During the design phase, you'll need to consider increasing the pitch diameters of the rolls from pass to pass (also called step-up).
API Engineering has been involved in the design and supply of a variety of custom built rolling mill stands for Seamless Tube Mills around the world. We supply everything from whole sets of stands to individual stands as well as replacement components for various processes including flat-rolling and shape-rolling.
Failure theories are used to predict when a material will fail due to static loading. They do this by comparing the stress state at a point with material pro...
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.

Fig 2 Typical 4-high stands showing various details. Pre-stressed mill stand – In a conventional rolling mill, the roller separating force which arises when the work piece bar is passed through the rolls is transferred through the backup rolls and their bearings to the mill house. In a pre-stressed mill stand, the two backup rolls are connected to each other by an …
Rolling Mills. Pepetools engineered a unique housing that maximizes durability and increases strength, all while decreasing overall mass. Pepetools is proud to be the only American manufacturer to produce, design, and build rolling mills in the USA.
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 ...
Four high rolling mills. Cluster rolling mills. Planetary rolling mills. Tendem or Continuous mills. 1. Two High Rolling Mills. It contains two heavy rolls fixed one over the other. The rolls are supported in bearing housed in sturdy upright frames (called stands) which are grouted to the rolling mill floor.
Specifically created for the tube, pipe, and roll forming industry, this software simulates the roll tooling design in order to predict the final result of the strip. This technology allows the designer to investigate multiple designs and materials in order to make any necessary revisions before the roll tooling is manufactured.

Steel Pipe and Manufacturing Processes Introduction. 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 ...
A typical example is TS6x4x1/4 where TS = Tube Steel, 6 and 4 are the actual width and depth in inches, and 1/4 is the wall thickness in inches. As of 2003, tube steel is now referred to as "Hollow Structural Section" (HSS) by the American Institute of Steel Construction. A typical designation is HSS6x4x1/4. 6.
