Steel tube is a type of structural tube used in many applications. From tiny pipes used in making hypodermic needles to large pipes that transport gas throughout cities, tubes are a vital component of the infrastructure of modern life.

While most people think of the term steel tube and pipe interchangeably, there are distinctions between the two based on their standards, measurements, and uses. Pipes are characterized by their outer diameter, which varies depending on wall thickness. Pipes also must be pressure rated to avoid leakages as they convey fluids or gases.

On the other hand, steel tube is characterized by its inner and outer diameters as well as its length. Tubing can be produced in round, rectangular, oval, trapezoidal or teardrop shapes and with many surface finishes. The precise dimensional tolerances of mechanical tubing are ideal for projects where the tube will be joined using brazing, flaring or other mechanical methods like couplings.

Advantages of Steel Tubes in Construction: Strength, Durability, and Sustainability”

Steel tubes are also manufactured to a variety of specifications and grades. For instance, cold rolled tubing starts as hot rolled steel but undergoes additional processing for enhanced finish and strength. Galvanized steel is treated with a zinc coating to provide resistance to corrosion. Pipes are also often rated for their maximum vacuum pressure, minimum bend radius and temperature range. All these factors are controlled during manufacturing to ensure that a product is suitable for its intended use.
