In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement

Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid

Results in higher shell side pressure drop

Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient

Can accomodate less number of tubes for a given shell diameter
