The basics of roll form tooling design

For the section in Figure 3, which is made of 0.060-in. cold-rolled steel with a yield strength of 35 KSI, a 2- or 3-degree overform is required to overcome the springback effect. Materials that have high elongation rates, such as aluminum, may need only 1/2 or 1 degree, while high-strength and high-yield materials may require 5 to 15 degrees ...

Separator sizing

Step 5. Select a vessel size that satisfies gas capacity, water-drop removal, and liquid-retention time requirements. An 84-in. × 13.4-ft separator satisfies the requirements, so you would round up to an 84-in. × 13.5-ft vessel. Similarly, a 90-in. × 12.5-ft separator would also be satisfactory.

Hexagon Calculator | 6

Using this, we can start with the maths: A₀ = a × h / 2. = a × √3/2 × a / 2. = √3/4 × a². Where A₀ means the area of each of the equilateral triangles in which we have divided the hexagon. After multiplying this area by six (because we have 6 triangles), we get the hexagon area formula: A = 6 × A₀ = 6 × √3/4 × a².
