Round steel pipe

Round Steel Pipe

Round steel pipe, commonly known as round hollow profile, is a versatile material with a unique combination of strength and flexibility. Its round shape coupled with inherent strength and durability makes it an essential component of numerous engineering projects. As a leading high-quality round steel pipes supplier, we are committed to providing our customers with the best products and services.

We offer a wide range of round steel pipe options, from seamless to welded, in a variety of sizes and wall thicknesses to meet different needs and applications. Our strict quality control ensures that each pipe meets the highest industry standards, guaranteeing strength, durability and reliability.

What Types of Round Steel Pipes Can be Classified into?

Round steel pipes can be classified according to different standards, and you can make some references below:

1.By manufacturing process:

  • Seamless steel pipe: made by processes such as perforation, without welds, suitable for high-pressure environments.
  • Welded steel pipe: made by welding steel plates or strips after curling and forming, the cost is relatively low.

2.By surface treatment:

Is Round Steel Stronger Than Square Steel?

Round steel generally has a higher tensile strength, which means it can withstand more force before breaking. This is because the round shape can make the stress distribution more even.

On the other hand, square steel has a higher bending strength, which means it can withstand more force before it buckles. This is because the square has more material on the outside edges where the bending force is applied.

So, the answer to your question depends on what you need the steel for. If you need it to withstand a lot of pulling forces, then round steel pipe is a better choice. If you need it to withstand a lot of bending forces, then square steel pipe is a better choice.

What is the Difference between Round Steel Pipe and Round Steel Tube?

The terms “round steel pipe” and “round steel tube” are often used interchangeably, but in industrial and engineering settings, they can have specific differences:

1.Purposes:

  • Pipes: are typically designed to carry fluids or gases under pressure. They are typically specified by their Nominal Pipe Size (NPS) and schedule (which determines the wall thickness).
  • Tubes: are typically used in structural applications or mechanical uses where exact dimensions and tolerances are more critical. Tubes are typically specified by their Outside Diameter (OD) and wall thickness.

2.Sizes:

  • Pipes: The nominal size of a pipe does not necessarily correspond to its actual inside or outside diameter. For example, a 2-inch NPS pipe has an actual outside diameter that is slightly larger or smaller than 2 inches, depending on the schedule.
  • Tube: The outside diameter (OD) and wall thickness are usually given as exact measurements. For example, a 2-inch OD tube has a wall thickness of 0.120 inches.

3.Materials:

  • Pipe: Can be made of a variety of materials, including steel, copper, plastic, etc., but the choice of material is usually determined by the requirements of the fluid being transported.
  • Tube: Also made of a variety of materials, but the choice may be more influenced by mechanical properties and structural requirements.
