The main purpose of the fin passes is to condition the strip edges to prepare them for welding. Learn more about versatile method designs. The Roll-Kraft versatile design method works very well on light-gauge, mild steel, or some higher tensile steels. It can be combined with a versatile design for maximum results on light-gauge, high-strength material. The W-style (reverse bending) method of designing breakdown rolls is recommended when forming high-strength very light or very heavy gauge materials. Learn more about standard edgeform design. Tooling made with this design is easier to set up than tooling made with the conventional design. This method is used to form a wide range of materials and gauges from mild steel to higher tensile (tension). The standard edgeform method of tooling design is the most widely used in the tube and pipe industry. Roll Tooling Design – Standard Edgeform Method Learn more about conventional method design. The single-radius design is very forgiving during setup since it is not as critical that it be centered like the other breakdown styles. If the gauge thickness is below 3% or above 8%, other styles of design are recommended, such as Edgeform, Versatile Edgeform, or W-Style. The conventional design is most commonly used when running multiple tube and pipe sizes made of mild steel with a T/D ratio (thickness divided by diameter) of between 3-8%.
