In daily life, people always mix “tube” and “pipe” generally and naturally. And let’s take a brief skim in the explanation of these two words in Oxford Dictionary:
Tube: A long, hollow pipe made of metal, plastic, rubber, etc., through which liquids or gases move from one place to another.
Pipe: A tube through which liquids and gases can flow.
It seems there are no differences between TUBE and PIPE. But actually tube differs from pipe in many aspects. Please spend a little time reading this article and I’ll inform in which aspects can we distinguish stainless steel tube from stainless steel pipe.
①Shape
Tube: Tube can be round, square, rectangular, or other shapes.
Pipe: Pipe is usually in round shape.
②Measuring Method
Tube: Tube is specified by outside diameter (OD) and wall thickness (WT).
Pipe: Pipe is specified by nominal diameter (inside diameter/ID) and schedule (wall thickness/WT).
③Primary Usage
Tube: Tube is widely used in every aspects of life, such as structural applications, instrument, heat-exchanger and etc.
Pipe: Pipe is normally used in transporting fluids and gases (liquids or gases) under pressure.
④Mechanical Characteristic:
Tube: Tube can be more flexible than pipe, allowing for bending and shaping.
Pipe: Pipe is generally rigid and not easily bent or shaped.
⑤Metal Types
Tube: Tube can be formed from cold-rolled or hot-rolled metal materials.
Pipe: Pipe is generally made from hot rolled metal materials.
⑥Size Difference
Pipe is typically available in larger sizes than tube.
⑦Manufacturing Requirements
Tube has stricter requirements that manufacturers need to account for, including thickness, straightness, and roundness of the cylinder. These requirements lead to a higher degree of testing and inspection on tube compared to pipe.
