Abstract

An apparatus for designing a tubing configuration comprising modules that receive tube design input, interpret a tube design input, calculate a final tube design, and display a final tube design. The tube design input may include point locations, bend criteria and end conditions, among others. The apparatus may further include modules that determine whether the tube design input exceeds a complexity threshold, comprises a minimum set of information, and comprises a conflicting or erroneous design. The apparatus may further include modules that determine and optimize the manufacturing cost as well as determine the manufacturability of the tube. The apparatus may further include modules that store operational challenges corresponding to emissions reduction features and secondary components.
