Proper selection of the size and materials for a piping system involves several basic design considerations. The first step involves determining whether to use piping or tubing. The next step is to establish the size for the pipe or tube, then to select the proper wall thickness, the surface roughness and finally the alloy selection based on the environment both inside and outside the tube.
Proper design of the piping system is fundamental to any fluid handling system. The more unique the fluid being transported the more critical the selection of materials and the design criteria.
