Dear All,

Basic question but needed to understand.
When we build a piping network which has fittings (obviously), the same material and thickness of Pipe will continue for the fittings also. Is there a provision to change the material and thickness (when necessary) for fittings alone, while in the loop? Or is it not necessary to change? Is this why SIFs' are calculated for fittings, to increase induced stresses with deduced factor?
