All calculations right from number of convolutions, width, fatigue life cycle, stress, weight, movement calculations, tie-rod, sleeve, shroud, end pipe length and vibration calculations are done automatically. After the calculations, SPULLOWS also generates manufacturing drawing in ACAD or any other 2D drafting software of the bellows with assembly and child part drawing along with BOM (Bill of Materials), Standards / Schedules used, a 3D model, and costing sheet. All these outputs are generated automatically by a click of a button. The material options in the software consist of all the standard materials used in the manufacture of bellows, like SS, MS, Inconel to just name a few of them. However, the user has an option to add a new material into the database by going to the Admin screen and adding new material.
