Pipe is round material manufactured to a "nominal" (not actual) inside diameter. Tube is round, square or rectangular hollow material manufactured to a specific outside diameter and wall thickness. Tubing is described by the actual outside diameter and wall thickness, i.e. 2" OD x .120 Wall Steel tubing. 

Pipe is described by the nominal (not actual) inside diameter with the wall thickness described by the term "schedule". Common pipe sizes are listed below.
