See Alloy Steel Tolerances

Alloy Steel Round Tube 4130 Normalized Seamless offers good strength and weldability without compromising steel abrasion or impact resistance. 4130 can also be made even stronger through heat treatment. It is typically used in structural applications, gears, fasteners, and aircraft exteriors.
Tube is designed to act as structural support, whereas Pipe is designed to carry liquid/gas/material from one place to another.
