What is the difference between Pipe and Tube..
People use the words pipe and tube interchangeably, and they think that both are the same. However, there are significant differences between pipe and tube.

The short answer is.. A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of the pipe conveyance capacity; a TUBE can be round, rectangular, squared or oval hollow section measured by outside diameter (OD) and wall thickness (WT), expressed in inches or millimeters.

 

Why a 1 ½ inch scaffold tube does not have a 1 ½ inch diameter
Anyone who works in scaffolding cannot avoid the number 48.3. No matter where you go, a scaffolding tube will always have a standard diameter of 48.3 mm. This number is still derived from its old unit of measurement of 1 ½ inches. And the fact that we do not continue to measure scaffold tubes, threaded tubes or similar in inches today also has a very specific purpose: uniformity. Errors and confusion can easily be avoided by using a uniform system of measurements. And it is precisely for this reason that the measurement of a scaffold tube in inches had to give way to the metric system in Europe and large parts of the world.


A scaffold tube does not even have 1 ½ inch diameter

You don’t even have to measure properly to realise that 1 ½ inches are 38.1 mm and not 48.3 mm. However, no one has made a mistake in the conversion from inches to metric, but the whole thing has historical reasons.

1 ½ inch scaffold tube diameter originally refers to the inner diameter. In order to produce a stable steel tube in the past, more material was needed due to the poorer quality of steel and production possibilities compared to today. Since more steel was needed for a stable tube, the tube walls were consequently thicker and the inner diameter was therefore smaller.
