+ What is pursued or guaranteed when determining an inside design diameter in a piping system?

+ Is there a direct relationship between the optimum inside diameter and the pressure load that a pipe element supports?

+ Which code is better than another?

+ Why do the main codes of the same family, e.g. ASME, have different thickness calculations and why?

+ What is the relationship between material selection and wall thickness?

+ What is the fundamental parameter from the point of view of material strength that will determine the starting point or standard of comparison for the calculations of pressure and mechanical stresses both internal and external in the codes?

+ What parameters or characteristics define a type of joint or fitting for a piping system?

+ What is flexibility and how does it relate to the term stiffness of the elements?

+ What is load and what is stress or strain?

+ Why is it essential to control mechanical stress levels in piping systems?

+ What is a constraint and what are degrees of freedom?

+ What are the main functions of supports?
